New AeroMax Growing Media From OASIS Grower Solutions Increases Hydroponic Crop Growth by Up to 30%
Engineered with a unique open matrix, the increased porosity of the new Horticubes® AeroMax growing media leads to greater airflow and maximizes the opportunity for oxygen to get to a plant’s root zone
(Kent, OH) – OASIS Grower Solutions, a worldwide leader in propagation and division of Smithers-Oasis Company, understands the importance of propagation. Not only helping plants grow but generating big ideas as well. The most recent of which is the revolutionary new substrate engineered for precision hydroponic farming called Horticubes® AeroMax.
New Horticubes® AeroMax growing media introduces a higher level of porosity for faster, healthier hydroponic crop root growth.
Before creating a new media to support the production of leafy greens, herbs, and other crops for hydroponic farming, Vijay Rapaka Ph.D., Global Research Manager set a rather lofty goal: “To create a smart substrate designed for today’s precision growing systems. Through extensive research over the last 24 months, we’ve achieved an ultra-low density that allows unrestricted root growth of young plants, so they can express their full growth potential of up to 30%. This innovative purpose is precisely why we named it AeroMax.”
Engineered with a unique open matrix, the increased porosity of the new Horticubes® AeroMax growing media leads to greater airflow and maximizes the opportunity for oxygen to get to a plant’s root zone. This helps crops grow faster and stronger, allowing young plants to prosper in the maximum air-filled substrate. Due to its enhanced porosity, air and nutrients constantly replenish a plant’s root zone, promoting stronger and healthier roots through each watering cycle.
The maximum airflow created with new Horticubes® AeroMax substrate helps get this young lettuce off to a great start.
Created with support from John Bonner of Great Lakes Growers, AeroMax has already delivered some impressive results. “The more porosity, the greater opportunity for air to contact the root zone,” begins Bonner. “And that happens more often with AeroMax, so we get fuzzy, almost hairy-looking roots. And when you get that type of growth, the plants simply grow faster. Since we started using AeroMax, we’ve seen faster crop growth upwards of 15%,” grins Bonner.
In addition to delivering greater oxygen to the crop’s root zone, AeroMax’s increased porosity and airflow enables it to drain more easily. This improved drainage keeps the top of the AeroMax growing media drier, dramatically reducing algae blooms and subsequent disease – creating a wonderfully clean and pathogen-free environment for young plants to grow.
Dr. Vijay Rapaka of OASIS® Grower Solutions and John Bonner of Great Lakes Growers review the incredible success of the new Horticubes® AeroMax.
AeroMax has a multitude of other functional benefits that support improved propagation. Its rich black color was strategically selected to increase the surface temperature and synergize well with photosynthetic light spectrum to produce more well-toned young plants. Plus, the less dense, almost spongy nature of AeroMax minimizes dust generation throughout the production process, making it easy to work with.
AeroMax has also been designed to separate easily at transplant through a unique etching around each cube, which also supports uniformity and precision growing. AeroMax growing media works well in NFT, Deepwater, and Vertical hydroponic systems, and is available in single-seed and multi-seed dibbled sheets of 50ct, 104ct, 162ct, and 276ct. The 50ct, 104ct, and 162ct sheets are top-grooved for easier separation.

USA - ALABAMA: Yellow Hammer Farms Opening Birmingham-Based Hydroponic Farm, Market
The farm and market will operate using technology that will be able to provide fresh and affordable produce year-round. A typical farm may be limited to five or six harvests a year for some crops, but Yellow Hammer Farms can have 11 to 12 harvests a year within its climate-controlled environment
Yellow Hammer Farms is opening a new indoor farm near downtown Birmingham. YELLOW HAMMER FARMS
Birmingham will have a hydroponic farm and market starting this weekend.
Owners Frank and Jillian Fitts will open Yellow Hammer Farms on June 18 at 702 Third Ave. N.
The farm and market will operate using technology that will be able to provide fresh and affordable produce year-round. A typical farm may be limited to five or six harvests a year for some crops, but Yellow Hammer Farms can have 11 to 12 harvests a year within its climate-controlled environment.
“From the beginning, our mission has been to bring Birmingham high-quality, locally grown produce," Frank Fitts said. "With so many of Birmingham’s residents living in a food desert, it was vital that we find a location where we could provide everyone a convenient option for affordable, fresh produce. Working in the food and beverage industry, I also saw firsthand the need and desire of restaurants and consumers wanting to purchase local produce throughout the year. So much of the produce that comes to this area travels a long distance. We are hoping to change that.”
The venture began with the Fittses converting an empty warehouse in the Titusville community. The building now is retrofitted with an advanced vertical hydroponic growing system to create a highly efficient, controlled growing environment that uses no soil. Water loaded with nutrients recirculates throughout the system, feeding the plants, while LED lights and a climate control system are overhead.
Crops that will always be on hand include basil, lettuce mix, kale, and other leafy greens and herbs. Other produce will be featured throughout the year, and 20 items will be available on June 18 for the grand opening.
Hours of operation will be Tuesday through Friday from noon to 6 p.m. and Saturday from 11 a.m. to 4 p.m
OptimIA Program Analyzes Fruitfulness of US Vertical Farms
In a research fact sheet, a USDA Specialty Crop Initiative team outlines results with a model for calculating profitability potential against various factors that impact the return on investment of CEA operations

As we have heard from many industry speakers and reported in horticultural lighting coverage, global urbanization and population growth will continue to put a strain on the food supply. Such wide-scale concerns also breed opportunities for innovative research which will ultimately support technology development that helps improve the food supply.
I recently learned of Optimizing Indoor Agriculture (OptimIA), a Specialty Crop Research Initiative (SCRI) supported by the US Department of Agriculture (USDA). The larger objective is to extend the knowledge base regarding controlled environment agriculture (CEA) — often referred to as indoor farming, vertical farming, and indoor agriculture — to support long-term goals of:
Increasing uptake of CEA practices
Addressing food supply — quality, quantity, and availability, particularly in areas where food inequities are prevalent
Bringing sustainable, profitable operations and techniques to CEA growers
The initiative draws from team members across education and commercial horticultural/agricultural organizations: Dr. Greenhouse, Inc.; Michigan State University; Ohio State University; Purdue University; University of Arizona; and the USDA Agricultural Research Service (USDA-ARS). Some of the participants are familiar names from speaking at past LEDs Magazine events, such as Purdue’s Cary Mitchell, MSU’s Erik Runkle, and Dr. Greenhouse president Nadia Sabeh.
Digging into the OptimIA website, I saw the project team had posted a fact sheet of research highlights titled “Potential Profitability and Economic Success of Indoor Agriculture in the United States.” These highlights were collected in preparation for contributing a chapter to the upcoming book Plant Factory Basics, Applications, and Advances. The fact sheet offers a balanced summary regarding challenges to quantification of profitability, benchmarking data, and other factors. Researchers used a Japanese Plant Factory with Artificial Lighting (PFAL), base-case model, to perform their analysis of the profitability of US-based vertical farming.
The most interesting points I have included in the infographic above. But this general conclusion from the highlights comes as no surprise, really: “The changes with the most potential to increase profitability are those that focus on enhancing market price for the quality of product delivered, decreasing capital costs, and improving elements of biomass (plant size, density, and type of crop).” You can download the fact sheet from the OptimIA website.
That’s where the hands-on research will come in and why we continue to refine the program for HortiCann each year. We continue to pursue experts with scientific findings, case studies, and system developments that can decrease the capital costs of horticultural solid-state lighting (SSL) and AgTech systems and enhance grower operations with solid data and monitoring for buildable results. For example, look to last year’s HortiCann presentations on updated research findings on light spectra for various plant characteristics, data-driven automation, and our blog on the grower panel, which centered around end-user experiences in applying LED lighting to greenhouse operations — lessons learned and how they plan to evolve operations with future updates.
Watch the HortiCann Light + Tech website for updates to the program and register to join us for the free virtual event Sept. 28–29, 2021.

Re-Nuble And KETOS Partner To Provide Turnkey On-Site Food Waste Recovery Solution For Soilless Farms
Re-Nuble’s on-site food waste recovery system helps soilless farms optimize their operations while reducing costs
By 24-7 Press Release
June 17, 2021
NEW YORK, NY, June 17, 2021 /24-7PressRelease/ — Re-Nuble has announced a new strategic partnership with water innovator KETOS today, providing soilless farms across the United States with a turnkey on-site food waste recovery solution. By combining the technology of Re-Nuble’s on-site food waste recovery system with the KETOS SHIELD, soilless farms will not only be able to produce their own free supplementary and sterile biostimulants and potable water for reuse, but they will also gain access to industry-standard lab data on the quality of their treated water.
Re-Nuble’s on-site food waste recovery system helps soilless farms optimize their operations while reducing costs. Through its Organic Cycling Science™ approach, farms can finally use a fully integrated, closed-loop, and self-sustaining nutrient system, capable of reducing input and disposal costs, while delivering biostimulants capable of improving crop yield and nutritional value. However, as water droughts and erratic weather patterns become more frequent, the need for resource efficiency using circular economy strategies, particularly water reuse, is becoming increasingly necessary.
“We’re here to help our clients be proactive about water reuse in order to create a fully circular food production and hedge their risks. For that reason, we saw an immense value add for our clients by partnering with KETOS,” commented Tinia Pina, Founder, and CEO of Re-Nuble.
The KETOS SHIELD is part of a fully integrated solution offering valuable water insights including automated reporting, real-time alerts, EPA-compliant or custom threshold-based diagnostics, custom reports, historical trends, and more. These insights are used for water quality, safety assurance testing, protecting liability, understanding process optimization, improving crop yields and water data for farming and protecting consumer health.
“We are pleased to partner with Re-Nuble, as water quality and conservation is critical for agricultural applications – particularly in instances where nutrient management, water availability, water quality and consistency, or product safety is essential,” said Meena Sankaran, Founder and CEO of KETOS. “For many farmers, poor nutrient management, a lack of water, low water quality, inconsistent or varied water sources, and safety concerns can have a significant impact on both revenue and profitability.”
Re-Nuble noticed this was a salient challenge for all farms but more prevalent amongst the growing indoor, controlled environment agriculture market due to the frequent wastewater discharges not reclaimed. However, the solution is also of interest to soil-based farms as more municipalities seek to limit nutrient runoff and water contamination, impacting underground water tables.
Today’s announcement builds on Re-Nuble’s mission to help global agricultural communities reimagine localized food waste for more sustainable growing practices.

Inside Larry Ellison's Futuristic Indoor Farming Company, Whose Massive, Tesla Solar-Powered Hawaii Greenhouses Are The First Step Toward An Ambitious Goal of Feeding The World
Sensei Ag is an agriculture-tech firm bent on changing the way food is grown worldwide. The company's mission is to feed the world by making produce more nutrient-rich and accessible and lowering the barrier to entry for vertical or greenhouse farming

Oracle billionaire Larry Ellison created an indoor farming company called Sensei Ag in 2018.
The goal of Sensei Ag is to feed the world by making produce more nutrient-rich and accessible.
Sensei Ag's Tesla solar-powered greenhouses grow produce that's distributed throughout Hawaii.
Picture this: You're driving along the highway on the island of Lanai, Hawaii's smallest inhabited island. All of a sudden, the verdant landscape gives way to futuristic greenhouses powered by an array of solar panels.
This is the first outpost of Larry Ellison's 3-year-old indoor farming company, Sensei Ag.
Sensei Ag is an agriculture-tech firm bent on changing the way food is grown worldwide. The company's mission is to feed the world by making produce more nutrient-rich and accessible and lowering the barrier to entry for vertical or greenhouse farming.
And while the company is young, it has the backing of Ellison, the tech titan whose net worth hovers around $95 billion and whose aggressive bet on the future of database management turned Oracle into a $200 billion behemoth.
Ellison's latest venture seems to have an equally ambitious outlook on the future.
"In the next three-to-five years, our goal is to feed the top three quintiles of the world with our products and employ the bottom two," Sensei Ag CEO Sonia Lo told Insider. "And then in the next eight-to-10 years, it is to feed everybody."
Here's how Sensei Ag is working to making indoor farming mainstream and use its Hawaiian homebase as a "lab for the world."
Sensei Ag is the brainchild of Ellison and Dr. David Agus, a cancer physician, and professor at the University of Southern California.
Larry Ellison, left, and Dr. David Agus. Sensei Ag
Ellison is the cofounder of cloud-computing firm Oracle. The 76-year-old billionaire, who announced last year that he moved to Lanai full time during the pandemic, is known for being something of an international playboy, as well as an outspoken advocate for health and wellness.
Ellison and late Apple CEO Steve Jobs were close friends for 25 years and often spent time hiking together near their neighboring homes in Woodside, California, prior to Jobs' death from pancreatic cancer in 2011. Ellison gave a eulogy at Jobs's funeral.
Agus, 57, is a prominent physician who treats patients with advanced forms of cancer and leads the USC cancer institute funded by Ellison.
Agus and Ellison became close friends while Agus was treating Jobs' cancer, according to Forbes.
Ellison and Agus founded Sensei in 2018, and recently split the company in two: A data-driven wellness spa called Sensei Retreats, and Sensei Ag.

Located at a Four Seasons resort known as Sensei Lanai, Sensei Retreats offers guests a customizable experience: They can set physical and mental goals for their stay, and the spa will track their sleep, nutrition, and blood flow.
Sensei's overarching goal is to help people live longer and healthier lives by improving sleep, movement, and nutrition, the company says.
Sensei Ag's primary focus is to bring healthy, affordable food to the masses by making indoor farming more accessible and more sustainable.

"Larry's perspective and David's perspective is that indoor growing is revolutionary and that we can move the needle on feeding people globally and diminishing water use and land use," Lo said.
This goal will come with significant costs and an ambitious technology rollout, she said but cited the environmental benefits of moving farming indoors, particularly when it comes to water use: Indoor farming is shown to use significantly less water than outdoor farming. Greenhouses use roughly 10% the amount of water used in an open field, and vertical farms use even less — closer to 3%, Lo said.
In addition to focusing on sustainability, Sensei employs a team of plant scientists who are working on maximizing the nutrients in the crops Sensei grows.
What makes Sensei Ag different from other indoor farming companies, Lo said, is that it works as a franchise model.
An exterior view of Sensei's greenhouses. Sensei Ag
For the average farmer, shifting to indoor production can be prohibitively expensive, which is what's held back the indoor farming movement up to this point, Lo said.
Farmers who opt for traditional outdoor growing have "a whole infrastructure that supports you," Lo said. That includes the ability to lease a tractor, lease land, and borrow other growers' cold storage and packing infrastructure.
"Whereas if you want to be an indoor grower, you have to come up with several hundred thousand dollars, at a minimum, if not several tens of millions," Lo said.
What Sensei Ag offers is the "whole franchise package." That includes helping a farmer identify the right indoor growing form factor for their farm, whether that's a glass greenhouse or an indoor farm; setting up a "cold chain," or refrigerated supply chain; and locking in transportation and logistics.
There's also a data component to what Sensei Ag is offering to farmers. Sensei tracks factors like crop selection and what type of light a grower users, then feed that information into a dataset to help inform future Sensei partners.
The produce grown by Sensei's partners can carry the Sensei Farms branding, and Sensei will help with distribution.

Lo said that a benefit to being one of Sensei's franchisees is the ability to distribute your produce at major US retailers.
"If you go to Walmart and you say, 'I have a 200,000-square-foot greenhouse and I want to deal directly with you,' Walmart will say, 'Oh gosh, you know, we really can't manage you as a vendor that's that small,'" Lo said.
"Whereas if you go to Walmart and you say, 'We're Sensei, and we have 200 farms across the US,' that's a risk that Walmart is willing to take," she said.
Not all types of crops are suited to growing indoors, and what's typically grown today meets a three-pronged threshold: good nutrition, reliability, and affordability.

Lo pointed to tomatoes as a good example of food that is almost entirely grown indoors, because growers can offer good value to customers.
"That's taken 15 years and it's taken a lot of technology, a lot of reliability of growing, a lot of just processes and procedures that have come into play," Lo said.
Lo predicted that the next crops to move primarily indoors will be leafy greens and strawberries. Strawberries, in particular, are becoming harder to grow outdoors due to a change in pesticide laws.
But there are downsides to indoor growing, particularly when it comes to energy use.

Indoor farms are often powered by coal, so they still have a carbon footprint.
And while there are vertical farms that are powered by solar energy, they require as many as 20 acres of solar panels, which means you're not really using less land.
At Sensei's farm on Lanai, there are six greenhouses spanning 120,000 square feet that are capable of producing over a million pounds of food per year, according to Forbes.
The greenhouses have sensors and cameras that track data about the farms, including water usage and airflow, and are powered by Tesla solar panels. (Ellison sits on Tesla's board.)
Lo called Sensei's farm on Lanai its "lab for the world."

"Islands are incredibly tough," she said, citing water, land, and labor constraints that make farming challenging on Lanai. But she said that the company has already met its initial goal of feeding the Hawaiian islands.
Sensei had its first harvest in August 2020, and by December, its produce was sold on every Hawaiian island. The food is packed on Lanai, then taken by barge to central Honolulu — from there, its distributed to the other islands, Lo said.
Food that's grown at Sensei Farms is distributed at the Nobu restaurant located inside the Sensei resort nearby, with the aim of measuring the effect the food has on people who visit the Sensei Wellness program.
"Now our goal is to not just make food an export of Lanai, but also to take the learnings from Lanai — the business processes, the franchising model on the island, the water conservation, the water reuse — and really make it an intellectual product and then export that intellectual product," she said.
She added: "If it works on an island in the middle of the Pacific, it will work anywhere."
USA: NEW JERSEY - Livingston Considers Resident's Sustainable Hydroponic Pilot Project Proposal
As the Township of Livingston continues to brainstorm ways to make the best use of its open spaces, Keith Hines and sustainable agriculture expert Tom Erickson recently proposed a hydroponic pilot project that would use a nutrient solution and water in lieu of soil for a community garden
By ELISE PHILLIPS MARGULIS
June 7, 2021
LIVINGSTON, NJ — As the Township of Livingston continues to brainstorm ways to make the best use of its open spaces, Keith Hines and sustainable agriculture expert Tom Erickson recently proposed a hydroponic pilot project that would use a nutrient solution and water in lieu of soil for a community garden.
After the duo’s initial proposal to implement the project at the Essex County Riker Hill Art Park fell through, the township is now looking into the possibility of doing so at the recently purchased Strahman Hill Park property.
Erickson recently presented a slideshow to the township illustrating how hydroponic technology works and demonstrating how hydroponic farming utilizes rain and solar power to grow healthy produce that can be donated to local food pantries.
“The project itself uses horticulture hydro-culture techniques to sustainably produce crops in an efficient organic manner with no impact to air, water or local environment, which is pretty important to us,” said Erickson, who also explained that hydroponics have a zero-carbon footprint. “We also plan on using the latest low-cost electronics to add a layer of control and monitoring that allows participation of the town administrators, fire, and police.”
According to Erickson, the hydroponic project could also provide unique educational opportunities for students interested in agricultural engineering and environmental sciences.
Erickson’s slideshow, much of which can be seen in the photos above, depicted a concept drawing of a greenhouse, plant-growing racks inside the greenhouse, the low-cost computer that would run the program, piping to transport the water and nutrient solution, sensors, a water pump, an aeration pump, a storage battery to operate the system at night and on rainy days, multiple solar panels and more.
He also demonstrated that easy-to-install solar kit power all water flow, aeration, lighting, monitoring, and security and that a basic, low-cost computer can monitor temperature, humidity, and liquid levels, security cameras, and sound or motion detectors.
“Our mission is to supplement the local food pantries in a sustainable, organic and efficient fashion with low environmental impact and potential for education,” said Erickson. “I think this has high potential to team up with the high school, the elementary school and open up doors to learning and training at the educational level.”
Hines, who is known in the Livingston area for his philanthropic endeavors, thanked the township council for considering a project that he feels would be important to the entire community.
“It's obviously incredibly high-tech stuff and really fascinating in terms of what can be accomplished with the technology and the fact that it's not going to have any footprint at all,” said Mayor Shawn Klein, who was impressed that the project has the potential to generate nutritious food for people who don't have access to it without causing problems with fertilizer or run off. “I think it sounds great, and hopefully we'll have a lot of success and be able to expand even in the same footprint as the county park or maybe even in town.”

AeroFarms: An Unproven Business With Enormous Risk
AeroFarms's mission is to grow the best plants possible for the betterment of humanity
June 13, 2021
Written by Jamie Louko
Spring Valley Acquisition Corp. (SV) APPHSVSVU
Summary
AeroFarms is a SPAC that is being brought to the market by Spring Valley Acquisition Corp. The deal was announced on March 26.
AeroFarms runs and operates vertical greenhouse farms. Unlike most greenhouses, AeroFarms' greenhouses take up little horizontal space, which allows them to pay less in expenses.
AeroFarms's mission is to grow the best plants possible for the betterment of humanity.
Currently, AeroFarms is not a buy, but it should be on a watchlist for investors to watch closely to see how well they can execute.
sompong_tom/iStock via Getty Images
Investment Thesis
AeroFarms (SV will become NASDAQ: ARFM) is a business that has high hopes, but with little edge from their other tech-savvy competitors, I struggle to see how they will be able to achieve the immense growth they are claiming. With poor financials and only $2.5 million in revenue, this business has not yet shown that it can achieve these expectations. Until AeroFarms can consistently show investors they are able to meet the guidance they set for themselves, it should be avoided by long-term investors.
SPAC Details
AeroFarms is being brought to the market by Spring Valley Acquisition Corp. This was announced on March 26. AeroFarms is expected to receive $317 million in cash from the deal, and the deal is expected to close in the second quarter of 2021, which would assume that AeroFarms would branch off into their Nasdaq listing, ARFM, within the month. However, SPACs usually take 4-6 months from announcement to go public, which would pin AeroFarms around July-September. September is on the longer side of this estimate, and considering estimates from Spring Valley and AeroFarms, a September target is likely inaccurate. I would expect that AeroFarms will go public sometime between late June and late July.
This process would estimate AeroFarms' equity value to be roughly $1.2 billion, which is slightly lower than another competitor that recently SPAC'ed in 2021, AppHarvest (NASDAQ: APPH). After the SPAC process, AeroFarms expects to nominate two of Spring Valley's existing directors, Debora Frodl and Patrick Wood, III, to its Board of Directors. Now that we have the basic details of the SPAC out of the way, let us dive into what AeroFarms does and why they are coming to the public markets.
AeroFarms' Mission
AeroFarms is a vertical greenhouse that is trying to change how Americans create sustainable food. This Certified B-Corp uses vertical farming, AI, and biological sciences to improve the way fresh produce is grown and distributed locally and globally. Their product, Dream Greens, "wins on quality, flavor, taste, and texture," and they sell in many major distributors like Whole Foods, ShopRite, Amazon Fresh, and FreshDirect.
AeroFarms was founded in 2004, and it became a B Corp in 2017. AeroFarms is trying to solve issues brought on by the megatrends of population growth, water scarcity, arable land loss, and climate change.
Source: Analyst Day Presentation
Currently, AeroFarms focuses on leafy greens, primarily bok choy, kale, micro broccoli, and arugula. AeroFarms' reason for existing today is to meet the need to solve issues brought on by climate change and other environmental issues. Due to strong droughts and water scarcity, water will be needed more and more if our world continues to use water at the pace we do today. AeroFarms uses 95% less water than traditional farms, which allows them to be less reliant on these problems, as well as open up water that would have been used to go towards other needs. This lack of water has also caused droughts, which can, in turn, lead to food shortages. Because AeroFarms' greenhouses are not as reliant on water, as well as the fact that they are indoors, these droughts are not as impactful to AeroFarms' business.
Source: Analyst Day Presentation
Simply put, AeroFarms sees great problems with our future if we continue to farm the way we do today, and they are trying to preemptively solve these problems.
Both co-founders are still involved, one as the CEO and the other as the CMO. Considering that AeroFarms was founded in 2004, it is clear that the founders are very dedicated to the vision and the mission of AeroFarms, and they will likely stay with the business for the long haul. If they founded this business simply to make a quick buck, the founders likely would have moved on already instead of dedicating 17 years of their lives to this business. This is a very good sign in my book. However, management is still extremely important for a business like this. If management were to cash out within a year of coming public, that would show me that the founders were not as dedicated as I thought, which would lower my conviction in this business to a more bearish conviction.
Being a SPAC, they were allowed to project revenues and estimates out to 2026. Therefore, it should come as no surprise that this company sees massive growth potential. They expect that vertical farming alone will be a $12.7 billion business by 2026, growing at over 22% 5-year CAGR. They also expect global fresh produce to become a $1.8 trillion industry by 2023, and leafy greens alone will contribute $108 billion to that large TAM. Clearly, this sort of farming is going to grow due to increases in demand (as the population increases). I have some skepticism as to whether it will be this large come 2023, but there is no doubt that the industry will be growing.
Quite frankly, it is near-impossible to correctly estimate how big this market will get. If it gets as big as AeroFarms claims it will, then AeroFarms will definitely have room to fight for market share and they will have vast opportunities to grow and become an amazing business. However, a 22% 5-Year CAGR in vertical farming is definitely aggressive. I worry that AeroFarms may be estimating on the extreme side, and that vertical farming will not grow that fast. If this is the case, then AeroFarms' potential will noticeably decrease, and it would make it a much less interesting investment.
Also, I am a firm believer that the world is going to need more greenhouses as it becomes harder to grow outdoors due to climate change and other sub-optimal weather conditions. There have been many recent droughts and other disasters that make it hard to count on reliable crops from outdoor farms, and greenhouses can minimize the impact that Mother Nature is having on our crop yields.
The sustainability of greenhouses is also a major benefit to society. The water usage is drastically lowered in greenhouses like AeroFarms, and so are emissions. These negative impacts are greatly reduced compared to traditional farms, so AeroFarms is not only helping create a sustainable supply of food, but they are also doing in a very environmentally friendly manner.
Their mission and drive to make our world better is the reason that I am writing about this stock today. I believe that AeroFarms and companies like it are trying to solve a major future problem for our world, and I am happy to give them attention for it. As I have mentioned a few times already, they have tons of competition. This competition is fierce, and it definitely has the potential to make AeroFarms fight for this market share.

As I have mentioned many times already, AeroFarms has some steep competition in the greenhouse space they are playing in. Although no major competitors are actively engaging in vertical farming (excluding one), they still have plenty of competition in the sustainable farming space.
Probably the company that first comes to mind is AppHarvest. I have written an article that dives deep into AppHarvest, but I will go over it quickly for anyone who is not extremely interested in AppHarvest. AppHarvest is a business that is based out of Kentucky and Appalachia. Unlike AeroFarms, which primarily focuses on growing leafy greens, AppHarvest's current focus is tomatoes. AppHarvest has plans in place to expand into leafy greens in a major way in the next 5 years, however. With their 60-acre farm (and 9 more facilities on the way), AppHarvest is planning to ramp up production in a major way.
AeroFarms is not expected to grow as fast as AppHarvest. Currently, the only things they are building is an R&D farm facility in Abu Dhabi, and another farm in Danville. The Abu Dhabi facility plans on breaking ground this month. They do, however, have a total of 3 farms, their biggest and only cash-generating farm bring their vertical farm headquarters in Newark, New Jersey. On April 29, 2021, AeroFarms announced that they are breaking ground and starting construction of their second farm, located in Danville, Virginia. Their third farm is the new facility in Abu Dhabi.
Clearly, both of these businesses are growing at a very fast rate. and there is no doubt that it will continue. Although they are not directly competing currently, they will likely be competing in the leafy greens area quite soon. In terms of technology, they are using similar kinds of tech, although I believe that AppHarvest has a very slight edge.

The main thing that gives AeroFarms an edge over AppHarvest is how they commercialize their product. One of the weaknesses I have with AppHarvest is how they sell their product. Simply, AppHarvest partners with a distributor, Mastronardi, who then is the sole buyer of AppHarvest's product and they distribute it out to larger companies. This results in a customer concentration for them. AeroFarms does not do this, but rather they partner directly with large businesses like Whole Foods. I like AeroFarms' distribution model much more than AppHarvest's.
I would be remiss if I did not briefly mention some of the private competitors. First, Bowery Farms, another vertical farming company that is private, is a major threat to AeroFarms. First, they are roughly double the size of AeroFarms. Second, they are operating in the same rough geographical region that AeroFarms is selling in. Bowery operates in New York, with plans to expand into Pennsylvania.
Source: Bowery Website
Bowery has 2 operating farms compared to just one for AeroFarms, and they are building one more today. These farms are in New Jersey and Maryland, which is quite intrusive on AeroFarms' market. Bowery also is planning on expanding into berries, tomatoes, and carrots, while they currently grow leafy greens. Due to greater size, they have been able to reach better economies of scale than AeroFarms, so their prices are actually lower currently. Bowery also sells in 850 grocery stores. Like AppHarvest and AeroFarms, Bowery is using a similar structure of technology that enables sustainability and limits pesticides in their farming.
Another strong (and private) competitor is Gotham Greens. They operate a very unique business model: instead of building large facilities, Gotham builds its greenhouses on the rooftops of its customers. This enables extreme freshness for its customer and nearby customers.
Source: Gotham Greens Website
Gotham Greens obviously has more greenhouses built and producing crops than any of the businesses mentioned. They have 8 greenhouses, encapsulating the Northeast, as well as the West of the U.S. Currently, they are operating and selling in 40 U.S. states. Freshness is clearly Gotham's edge over AeroFarms, however, their business model can be both a blessing and a curse. Gotham is limited to small greenhouses, whereas large, 60-acre greenhouses like AppHarvest's are much more cost-effective. AeroFarms sits in the middle of these sizes for its facilities.
All of these businesses have their own edge, and it is still unknown which will make the greatest difference. However, farming is by no means a winner-take-all market. There will be many winners in this space, and potentially even all of these competitors could be successful along with AeroFarms. To quickly summarize, each company has benefits that separate them from the pack. AppHarvest has its central location (Kentucky), Bowery has strong economies of scale due to its size, and Gotham has its ability to deliver the freshest products. Now, I am going to take a look at what makes AeroFarms special compared to some of its competitors.
The Edge
Compared to traditional farming, AeroFarms' technology and sustainability is what separates them. Due to the nature of greenhouses, AeroFarms can have tight control on conditions that the plants experience, so AeroFarms can create the most optimal environment for the plants to grow faster, and be of the highest quality. They also excel at full automation of their farm. Everything from seeding to packaging their produce is fully automated.
Source: Investor Presentation
AeroFarms uses data science and a fully-controlled technology platform that enables it to better understand plants and optimize farms while improving quality and reducing costs. Simply, they are analyzing plant biology to optimize the growth of these plants.
Teams of plant scientists develop custom algorithms to precisely define the conditions each plant needs to thrive. This understanding allows AeroFarms to optimize performance, cultivate new varieties, improve quality, lower costs and optimize efficiency.
Source: Investor Presentation
This understanding of the biology of plants is extremely important for AeroFarms. One of the primary benefits they have over traditional farming is that they can create the best-looking and tasting produce. Understanding exactly how plants thrive and do this is crucial. If they were to expand into different products, such as berries or tomatoes, they would have to do this again. This knowledge may take time to learn, and if they are testing environments to see which one produces the best crops, it could take a while. However, once learned, this can be easily replicated in dozens, if not hundreds, of other facilities. Once AeroFarms learns that leafy greens thrive under (and these numbers/metrics are not accurate but for the example) 75-degree heat with high sun exposure and light water levels, they can replicate those conditions in whatever facility they grow leafy greens in. This intellect is somewhat time-consuming to learn, but once it is learned, it gives the company a massive advantage.
Through the integration of these disciplines, AeroFarms achieves up to 390 times greater productivity per square foot annually versus traditional field farming while using up to 95% less water and zero pesticides. Therefore, due to the productivity, clearly the knowledge that they learned from the data and plant biology is paying off.
Source: Investor Presentation
Another thing that most traditional famers do not have is data. AeroFarms can create lasting network effects and benefit greatly from scale if they can efficiently use and act on data they receive from their facilities.
Lastly, AeroFarms has been creating a strong library of IP since its founding. With over 250 invention disclosures and a vast library of data collected over 15 years of operations, AeroFarms is continually improving its systems to understand plants at unprecedented levels and solve agriculture-related supply chain issues. Currently, AeroFarms has 15 granted patents, with 38 more pending approval. They also have 46 designated trade secrets. The vast amount of trade secrets show that they want to keep its operations relatively unknown to its competitors, so they do not elaborate much on what those secrets entail. However, their strong number of patents show that they have actual technology that is working effectively and it is independent to them. No other greenhouse or direct competitor could do the same thing AeroFarms is doing in some of its capacities.
AeroFarms plans on bringing these trade secrets to future facilities, with plans to start construction on three farms, none of which have been announced or actually planned yet, by the start of 2023. AeroFarms also sees strawberries as a major growth avenue. Strawberries are highly cyclical due to growing conditions and they carry lots of pesticides, both of which AeroFarms is trying to solve in the farming universe.
AeroFarms has a clear edge above traditional farming, just as AppHarvest, Gotham, and Bowery do. Where I struggle to find an edge is between the technology of these businesses. After looking at the technology for all of these businesses, the results seem to be the same: more efficient production and productivity, better tasting produce, less use of water, greater sustainability. Also, all of these businesses have some sorts of patents that make their business stand out. Personally, I believe that it is not the technology that gives AeroFarms an edge over its competition, nor do I think it is vertical farming (itself).
Vertical farming alone does not provide any greater benefits over non-vertical farms in terms of quality of produce. However, I believe the optionality that comes from vertical farming when it comes to growth is the edge for AeroFarms. Unlike AppHarvest, where they need 60 acres of land to have a 60-acre farm, AeroFarms only needs a small portion of that land. With even a 48-towered farm, AeroFarms could theoretically create the same sized farm in a fraction of the horizontal size of one of AppHarvest's farms. This is beneficial in one primary way: AeroFarms would be able to go to places AppHarvest would not. For example: AeroFarms' HQ is in Newark, New Jersey. AppHarvest could never find a large enough space in that city to build a farm, but AeroFarms can.
Simply, AeroFarms has the agility in its farms to travel to cities and more urbanized geographies that competitors like AppHarvest cannot. This can give them an edge, for if both AppHarvest and AeroFarms are selling in the same city, but AeroFarms actually has a greenhouse in the city, grocers would likely sell more AeroFarms' products because of locality and freshness.
Financials and Valuation
Financially, AeroFarms is quite lacking. AeroFarms has over $48 million in cash and no long-term debt, which is wonderful, but that is just about where the good news stops. Their net revenues were $2.5 million for the FY 2020, yet their cost of goods sold was almost $8 million, resulting in a gross profit loss of $5.4 million. As they continue to scale, at least for a while, this number can get worse too. AeroFarms is spending a whopping $17 million in SG&A compared to only $1 million in R&D. This is exactly the opposite of what I want to see in a business. I want their R&D expenses to be high, because it shows me that they are heavily investing in the future of their business.
All of this combines for a grand net income loss of over $25 million. However, as most SPACs do, they are projecting monstrous growth.
Source: Investor Presentation
They are expecting their current one farm to grow to 16 farms and their revenue to grow to $553 million (from the $4 million today) by 2026. They also expect their gross margins to be roughly 50% by 2026, which is high for any farming business. EBITDA margin is also expected to reach a whopping 35%. AeroFarms is clearly spinning an optimistic story with these growth projections, and I am not sure how confident I am that they can get that done. Transitioning from negative to positive gross margin is going to be hard enough for them, and I think it will take at least until 2023 for them to do that. Therefore, the fact that they believe that they will have margins of 50% just 3 years after turning their gross profit positive is a bit of a stretch to me. I have no doubt that this company will grow, but I do doubt that they will be able to grow at such a high rate.
Also, they project that they will be able to get 3 new farms up and running and producing every single year until 2026. That is extremely optimistic growth. AeroFarms only broke ground on 2 farms recently, and they are expecting to build both of those up to production capacity in 1.5 years? That is quite aggressive. Not to mention that they would still need to find another area to build a farm, build it, and start producing crops in that same time frame. That is an extremely tall order, just to meet 2022 estimates. Then they have to do that again, and again, until 2026, just to meet guidance. Not exceed, just meet.
Clearly, I am quite skeptical about how rapidly they will be able to grow. Personally, I do not think they will be able to do this, and for me, a company that does not meet their own expectations is not worth an investment. For me, missing expectations gives me a lack of confidence in the ability of management, and therefore I lose trust. AeroFarms has not missed any expectations yet, but they have a tall order ahead of them, and any small slip in any form would likely cause consistent misses on growth estimates.
Considering that this business has not become its own public company yet, the valuation metrics are slim. Also considering that this business is gross profit negative, operating income negative, EBITDA negative, and net income negative, the only valuation metric available is Price-to-Sales Ratios.
Valued at $1.2 billion, AeroFarms has $2.5 million in sales (let's say $3 million to be super generous). At these metrics, AeroFarms' P/S Ratio would be 400. This is absolutely ludicrous. Even at AppHarvest's insanely optimistic revenue estimates, their forward 2023 P/S Ratio is over 22.
It does not help that I am skeptical on AeroFarms' own estimates for the success of their business, but 22x forward sales is quite an expensive multiple. At those high forward multiples, I would stay far away and make sure they execute and (hopefully) beat their expectations. If they can meet or beat their revenue guidance, maybe these valuations can be justified, but until they prove my skepticism wrong, this company is extremely highly valued for no good reason at all.
Why I'm Not Buying Today
Today, this business should not be touched with a 10-foot pole. The reasoning for this ultimately comes down to two concepts: Their technology is not drastically different than its direct competitors, and their financial situation is simply miserable. The first one is going to be hard to fix, which is why I am likely to remain bearish on the business, but the second one could change within the next 2-3 years. In which case, I would likely take another look at this business and rethink my thesis. For the meantime, while they are still gross profit negative, investors should definitely stay away.
Lastly, I must mention again that the valuation and AeroFarms' guidance are insane. AeroFarms' guidance assumes some of the largest growth we have seen in any modern day company, within only 5 years. These growth estimates might be accurate if they were placed out 7-10 years in the future, but 5 years for this business to go from its first sales to fully-scaled economics is highly unlikely. Even if we assume these drastic growth rates, their valuation is still quite high.
Investors should stay away from AeroFarms for now, but watch it closely for the next 2-3 years. As this business operates, we can watch to see how they prove themselves out. If they can consistently meet their own guidance and expectations, then AeroFarms' might be investment material. Until, however, they have some time to prove themselves out, AeroFarms is merely a company with little edge that is hopeful to grow at astronomical rates. Today, this business is not worth the high risk of investment.

Airgarden Uses NASA-Designed Technology To Give Sustainable Produce An Easy Win
Airgarden, Australia’s very first vertical soilless gardening system, is making use of the technology for the benefit of anyone obsessed with sustainable design – or for those who just want access to more home-grown produce, faster
Does Your Home Benefit From The Use
of Astronaut Technology?
No. Let’s Change That, Shall We?
Airgarden, Australia’s very first vertical soilless gardening system, is making use of the technology for the benefit of anyone obsessed with sustainable design – or for those who just want access to more home-grown produce, faster.
The game-changing gardening system is said to sprout 5 times more home-grown produce, 3 times faster, with 95% percent water. What’s more, is that the Airgarden takes up 1sqm of space so your petite inner-city apartment is no excuse to not get your green thumb on.
“The idea stemmed from wanting to grow fresh produce that was good for us, and the environment while living in the inner city,” said co-founder Prue Bauer, who started Airgarden with her brother Tom. “We were sick of throwing out so much of what we bought and wanted quality produce that didn’t cost an arm and a leg. More and more people are thinking about what they are putting in their bodies and the cost of organic food was unsustainable long term, so we knew there has to be a better solution.”
NASA-developed aeroponics technology – which has been approved by horticulturalists – is typically used to grow plants in space. Tom and Prue wisely repurposed that to allow anyone to grow their own urban farms with no digging, weeding, or watering required.
Even if the game-changing potential for giving life to your inner-city apartment doesn’t win you over. The money-saving potential surely will. With Airgarden, budding home-gardeners can sprout up to 150 different types of fruits and vegetables to feed a family of four each week. That is a significant cut to the weekly grocery run, and an easy way to incorporate more lush, leafy greens in your diet.
Airgarden is already being picked up in some sustainably-minded restaurants across Australia, including Halcyon House’s Paper Daisy restaurant, Manly Boathouse, and Wild Canary. Undoubtedly that list is going to be growing in no time, especially given as it’s a way for a restaurant to grow their own on-site garden without actually having the space (or rooftop) to do so.

What Is Aeroponics?
Aeroponics is an advanced variation of hydroponics where plants are suspended in the air; their roots dangle down and are periodically misted with water from a timed sprinkler system connected to the main nutrient reservoir
How Aeroponics Works,
Types, And Pros, And Cons
June 14, 2021
Aeroponics is an advanced variation of hydroponics where plants are suspended in the air; their roots dangle down and are periodically misted with water from a timed sprinkler system connected to the main nutrient reservoir. This soilless growing method is best for plants that need more oxygenation since aeroponic roots aren’t hampered by dense soil or thick growing mediums. Depending on the plant and specific type of aeroponics system, the grower typically uses little to no growing media at all.
In aeroponics, a specially designed pump and spray system is submerged into the nutrient-water solution and timed to release short mists of water to the plants’ roots throughout the day. Because roots will have more access to oxygen and humidity in an aeroponics system, they often grow two to three times larger and yield far bigger numbers than traditional farming methods. Generally, it also uses less water over time since excess water not absorbed by the roots is drained back into the nutrient tank, and the mist allows for higher concentrations of nutrients with less liquid.
Most of the plants that work with hydroponics will thrive in an aeroponics system, from leafy greens and herbs to tomatoes, cucumbers, and strawberries, but with additional perks. Because of the exposed root qualities of aeroponics systems, root vegetables like potatoes that would otherwise be ill-suited for hydroponics systems will flourish as they’ll have more room to grow and be easier to harvest.

Aeroponics in Space
NASA began experimenting with aeroponics as early as 1997, planting adzuki beans and seedlings aboard the Mir space station in zero gravity and comparing them to controlled aeroponic gardens on Earth treated with the same nutrients. Amazingly, the zero gravity plants grew more than the plants on Earth. Aeroponics can not only provide long-mission deep-space NASA crews with fresh food, but it also has the potential to provide them with fresh water and oxygen.
How Does Aeroponics Work?
The seeds are planted somewhere they’ll stay in place, such as pieces of foam, pipes, or foam rings, which are then wedged into small pots or a perforated panel with a tank full of nutrient solution below. The panel elevates the plants so they’ll be exposed to the natural (or artificial) light and circulating air, providing light on the top and nutrient mist on the bottom, and an enclosure around the roots helps keep the moisture in. A timed pump rests inside the tank or reservoir, pumping solution up and through spray nozzles that mist the roots, with excess liquid draining straight down through an outflow chamber back into the reservoir. At the next timed interval, the entire cycle starts again.

Nutrients for aeroponics systems, like hydroponics, come packaged in both dry and liquid forms. Depending on the plant and growth stage, primary nutrients may include nitrogen, phosphorus, and potassium, while secondary nutrients can range from calcium and magnesium to sulfur. It is also important to consider micro-nutrients, such as iron, zinc, molybdenum, manganese, boron, copper, cobalt, and chlorine.
In aeroponics systems where the nutrient solution is continuously recycled, the pH measurements need to be taken regularly to ensure that enough nutrients are getting absorbed into the plants.
Natural Aeroponics
Aeroponics occurs in nature, specifically in more humid and wet regions like the tropical islands of Hawaii. Near waterfalls, for example, plants will grow vertically on the rocks with their roots openly hanging in the air, the spray from the waterfall moistening the roots under the right conditions.
Types of Aeroponics
There are two types of commonly used aeroponics: low pressure and high pressure. Low pressure is the most used by home growers since it is low cost, easy to set up, and its components are easier to find. However, this type of aeroponics often uses a plastic spray nozzle and a typical fountain pump to deliver nutrients, so the droplet sizes are not exact and can sometimes waste more water.
High-pressure aeroponics, on the other hand, distributes nutrients through a highly pressurized nozzle that can deliver smaller water droplets to create more oxygen in the root zone than low-pressure techniques. It is more efficient, but much more costly to set up, so it tends to be reserved for commercial production rather than hobbyists.
High-pressure systems typically mist for 15 seconds every 3 to 5 minutes, while low-pressure systems may spray for 5 minutes straight every 12 minutes. Experienced growers will adjust the spraying interval according to the time of day, watering more frequently at night when the plants are less focused on photosynthesis and more focused on taking up nutrients. With both types, the reservoir solution is kept at a temperature range between 60 F and 70 F in order to maximize the absorption rate of the plant. If the water becomes too hot, it is more susceptible to algae and bacteria growth, but if it gets too cold, the plants may start to shut down and not take as many nutrients as they would at a more optimal temperature.
Aeroponics at Home
While some growers choose to use horizontal aeroponic systems similar to traditional soil farming, vertical systems can save more space. These vertical systems come in all shapes and sizes, even small enough to be used on a back porch, balcony, or even inside an apartment with the appropriate lighting setup. In these smaller systems, misting devices are placed on top, allowing gravity to evenly distribute the nutrient solution as it spreads downward.
Neznam / Getty Images
Aeroponics kits are available to make the setup process easier for beginners, but it is also possible to design and build your own system at home, similar to hydroponics, with tools found at most local gardening stores. Due to the complicated and expensive nature of high-pressure aeroponics, it is always prudent for beginners to start off with a low-pressure system before working their way up to more technical operations.
Fun Fact
The first recorded use of aeroponics happened in 1922 when B.T.P. Barker developed a primitive air plant-growing system and used it to research plant root structure in a laboratory setting. By 1940, researchers were frequently using aeroponics in plant root studies, as the dangling roots and lack of soil made it much easier to observe changes.
Pros and Cons
One of the most significant advantages of aeroponics systems is the fast and high crop yield and the fact that it uses the least amount of water over time compared to hydroponics and aquaponics. Roots are exposed to more oxygen, helping them absorb more nutrients and grow faster, healthier, and larger. Also, the lack of soil and growing medium means that there are fewer threats of root zone diseases.
On the flip side, aeroponic system chambers are constantly being sprayed with mist, keeping them wet and prone to bacteria and fungi; this can be remedied by cleaning and sterilizing misters and chambers regularly.
Affordability Factor
Studies show that the cost of growing a tuber (such as potatoes, jicama, and yams) using aeroponics is about one-quarter less than the cost of a conventionally grown tuber.
Due to the circular nature of the watering system and the higher nutrient absorption rate, aeroponics uses considerably less water than similar farming systems. Aeroponic equipment is also easier to move and requires much less space (nurseries can even be stacked on top of each other like a modular system). In a study comparing lettuce growth aeroponics, hydroponics, and substrate culture, results showed that aeroponics significantly improved root growth with greater root biomass, root-shoot ratio, length, area, and volume. The study concluded that aeroponics systems may be better for higher-valued crops.

Because the plants aren’t submerged in water, aeroponics is completely dependent on the misting system. If anything malfunctions (or in the event of power outages), then the plants will quickly dry up and die without water or nutrients. Seasoned growers will think ahead and have some sort of backup power and misting system waiting in storage in case the primary one fails. The system’s pH and nutrient density ratio is sensitive, and will require plenty of hands-on experience to understand how to properly balance them; as there is no soil or media to absorb the excess nutrients, proper knowledge about the perfect amount of nutrients is essential to aeroponics systems.

Eco-Friendly Smart Farms Based On Nutrient Solution Recirculation
UV sterilization and microbial stability analysis used to recycle nutrient solution; proposed method minimizes the use of fertilizers and water by hydroponic farms

UV sterilization and microbial stability analysis used to recycle nutrient solution; proposed method minimizes the use of fertilizers and water by hydroponic farms
NATIONAL RESEARCH COUNCIL OF SCIENCE & TECHNOLOGY
The development of new urban agriculture technologies, such as vertical and smart farms, has accelerated rapidly in recent years. These technologies are based on hydroponic cultivation in which plants are grown using nutrient-rich solutions rather than soil. Approximately 20-30% of the nutrient solutions used during hydroponic cultivation are discharged without being absorbed by the crops, and because most farmers in South Korea do not treat the discharged solutions, hydroponic farms contribute significantly to environmental pollution.
This problem can be reduced if hydroponic farms use a recirculating hydroponic cultivation method that reuses the nutrient solutions after sterilizing them with ultraviolet (UV) light, instead of discharging them. However, two main issues complicate the implantation of such recirculation systems. First, the potential for diseases and nutrient imbalances to develop owing to microbial growth in the recycled nutrient solutions must be eliminated. Second, the initial investment required to set up a recirculating hydroponic cultivation system is often prohibitive, costing hundreds of millions of Korean won per hectare.
However, a new study conducted by researchers at the Korea Institute of Science and Technology (KIST) proposes a method that can stably manage the microbial population in recirculating hydroponic cultivation systems. The research team, led by Drs. Ju Young Lee and Tae In Ahn of the Smart Farm Research Center, KIST Gangneung Institute of Natural Products, conducted an integrated analysis of the microbial growth characteristics by constructing a model that simulates the flow of water and nutrients, and the inflow, growth, and discharge of microorganisms in recirculating and non-circulating hydroponic cultivation systems. Their simulations revealed that the microbial population in recirculating hydroponic cultivation systems can be controlled by adjusting the UV output and the water supply. On the contrary, in non-circulating hydroponic cultivation, the microbial population fluctuates considerably depending on the amount of water used, increasing sharply if there is too little water.

High cost has restricted the use of UV sterilization systems in hydroponic farming in Korea And prompted the research team to develop their own UV sterilization system, with further studies underway to commercialize this system as an economical alternative to imported systems.
The results of the study have already received strong interest: the rights to the operation and management software technology for recirculating hydroponic cultivation has been acquired by Dooinbiotech Co., Ltd. for an advance fee of 80 million won (8.5% of the operating revenue), while an agreement is in place with Shinhan A-Tec Co., Ltd. for the advanced recirculating hydroponic cultivation technology for an advance fee of 200 million won (1.5% of the operating revenue). Commercializing the recirculating hydroponic cultivation system is expected to reduce fertilizer costs by approximately 30~40%, which equates to 30 million won per year based on a 1-hectare farm.
Commenting on the envisaged impacts of the study, Dr. Ju Young Lee said, "The developed system makes the transition to eco-friendly recirculating hydroponic cultivation systems an affordable option for many more farmers." Dr. Tae In Ahn added, "We are also developing software and operation manuals to guide farmers in managing the nutrient balance in the solutions to increase the number of farms using the recirculating hydroponic cultivation system."

CANADA: The Value of Hyper-Local Produce
At Yellowknife Co-op, produce is grown steps away from the store in a container farm!
The hyper-local food trend is more than just a fad: there’s a reason that hyper-local food is catching on in a big way. If you’re thinking about growing hyper-local food, it’s important to understand the value of the product and its market position.
At Yellowknife Co-op, produce is grown steps away from the store in a container farm!
BUT FIRST, WHAT IS HYPER-LOCAL FOOD?
Where does that ‘local’ head of lettuce you pick up from the grocery store actually come from? The Canadian Food Inspection Agency (CFIA) defines ‘local food’ as being grown in the province where it’s being sold, or within 50km of the border. But hyper-local food is even more local than being from the same province or being Canadian-grown. It is usually grown within the same town or city, or a short distance from where it’s being sold (sometimes even right behind the store!).
BENEFITS OF HYPER-LOCALLY GROWN FOOD
LOWER FOOD MILES
Hyper-local produce is usually grown within the same town or city, or a short distance from where it’s being sold.
As consumers are becoming more and more aware of the environmental impact of our food choices, the demand to lower food miles is also growing. A food mile can be thought of as the distance that food travels from the grower to the consumer. As a metric, it helps to assess the environmental impact of the foods we consume. A 2012 study showed that on average, 30% of food is imported in Canada, leading to annual emissions of 3.3 million metric tonnes of CO2.
Growing food hyper-locally can result in significantly lower food miles (and as few as zero food miles!) in both urban centres and rural communities. This reduces the carbon footprint of what you eat.
SUSTAINABLY GROWN
Growing hyper-locally in a hydroponic farming system has further benefits. Water in a closed hydroponic system is captured and reused, resulting in 90% less water use, and 95% less land than conventional farming.
TRACEABLE FOOD CHAIN
Growing hyper-local is completely traceable. This means you know exactly what’s going into your product. There are no synthetic pest control products, less risk for E.Coli, and a shorter supply chain to manage.
FRESHER PRODUCE WITH A LONGER SHELF LIFE
Growing food hyper-locally also means fresher produce and a longer shelf-life. Instead of wilting in a truck for hundreds of kilometers, hyper-local produce is shelf-ready immediately. This has a marked effect on the quality, as most produce loses 30 percent of nutrients just three days after harvest.

“When you get your hands on the fresh produce and taste it, you know it’s a good thing for your community in general. It’s really easy to get excited and pumped about [this project].” - Ian Maxwell from Norway House.

WHERE IS HYPER-LOCAL PRODUCE POSITIONED IN THE MARKET?
For growers, it’s important to keep in mind that hyper-local food isn’t competing with foreign produce that you typically find in grocery stores. Between locally-grown vs imported food, the wholesale price for foreign produce is cheaper than local produce.
Keep in mind that grocery stores buy produce at wholesale prices, which means that they may buy produce from you at a certain cost, and then sell it with a 30% margin added to the price. When you walk into a grocery store and see produce being sold for $4.99, the reality is that the grocery store-bought it for $3.50 and added a mark up to the final price to help cover their costs of operations.
To find price-compatible products for market research in your area, look for products that will match your future products, such as living lettuce, other hydroponic greens, and other hyper-local, organic produce. Growcer greens belong in the hyper-local, value-added produce category.
GETTING STARTED WITH HYPER-LOCAL FOOD
Growing hyper-local food has many benefits: not only is it fresher, healthier, and better for the planet, it can also be a profitable investment for growers. When crafting your financial projections, keep in mind the value of hyper-local produce and where it sits in the market.

MIT Engineers Have Discovered A Completely New Way of Generating Electricity

Tiny Particles Power Chemical Reactions
A new material made from carbon nanotubes can generate electricity by scavenging energy from its environment.
MIT engineers have discovered a new way of generating electricity using tiny carbon particles that can create a current simply by interacting with liquid surrounding them.
The liquid, an organic solvent, draws electrons out of the particles, generating a current that could be used to drive chemical reactions or to power micro- or nanoscale robots, the researchers say.
“This mechanism is new, and this way of generating energy is completely new,” says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT. “This technology is intriguing because all you have to do is flow a solvent through a bed of these particles. This allows you to do electrochemistry, but with no wires.”
In a new study describing this phenomenon, the researchers showed that they could use this electric current to drive a reaction known as alcohol oxidation — an organic chemical reaction that is important in the chemical industry.
Strano is the senior author of the paper, which appears today (June 7, 2021) in Nature Communications. The lead authors of the study are MIT graduate student Albert Tianxiang Liu and former MIT researcher Yuichiro Kunai. Other authors include former graduate student Anton Cottrill, postdocs Amir Kaplan and Hyunah Kim, graduate student Ge Zhang, and recent MIT graduates Rafid Mollah and Yannick Eatmon.
Unique properties
The new discovery grew out of Strano’s research on carbon nanotubes — hollow tubes made of a lattice of carbon atoms, which have unique electrical properties. In 2010, Strano demonstrated, for the first time, that carbon nanotubes can generate “thermopower waves.” When a carbon nanotube is coated with layer of fuel, moving pulses of heat, or thermopower waves, travel along the tube, creating an electrical current.
That work led Strano and his students to uncover a related feature of carbon nanotubes. They found that when part of a nanotube is coated with a Teflon-like polymer, it creates an asymmetry that makes it possible for electrons to flow from the coated to the uncoated part of the tube, generating an electrical current. Those electrons can be drawn out by submerging the particles in a solvent that is hungry for electrons.
To harness this special capability, the researchers created electricity-generating particles by grinding up carbon nanotubes and forming them into a sheet of paper-like material. One side of each sheet was coated with a Teflon-like polymer, and the researchers then cut out small particles, which can be any shape or size. For this study, they made particles that were 250 microns by 250 microns.
When these particles are submerged in an organic solvent such as acetonitrile, the solvent adheres to the uncoated surface of the particles and begins pulling electrons out of them.
“The solvent takes electrons away, and the system tries to equilibrate by moving electrons,” Strano says. “There’s no sophisticated battery chemistry inside. It’s just a particle and you put it into solvent and it starts generating an electric field.”
“This research cleverly shows how to extract the ubiquitous (and often unnoticed) electric energy stored in an electronic material for on-site electrochemical synthesis,” says Jun Yao, an assistant professor of electrical and computer engineering at the University of Massachusetts at Amherst, who was not involved in the study. “The beauty is that it points to a generic methodology that can be readily expanded to the use of different materials and applications in different synthetic systems.”
Particle power
The current version of the particles can generate about 0.7 volts of electricity per particle. In this study, the researchers also showed that they can form arrays of hundreds of particles in a small test tube. This “packed bed” reactor generates enough energy to power a chemical reaction called an alcohol oxidation, in which alcohol is converted to an aldehyde or a ketone. Usually, this reaction is not performed using electrochemistry because it would require too much external current.
“Because the packed bed reactor is compact, it has more flexibility in terms of applications than a large electrochemical reactor,” Zhang says. “The particles can be made very small, and they don’t require any external wires in order to drive the electrochemical reaction.”
In future work, Strano hopes to use this kind of energy generation to build polymers using only carbon dioxide as a starting material. In a related project, he has already created polymers that can regenerate themselves using carbon dioxide as a building material, in a process powered by solar energy. This work is inspired by carbon fixation, the set of chemical reactions that plants use to build sugars from carbon dioxide, using energy from the sun.
In the longer term, this approach could also be used to power micro- or nanoscale robots. Strano’s lab has already begun building robots at that scale, which could one day be used as diagnostic or environmental sensors. The idea of being able to scavenge energy from the environment to power these kinds of robots is appealing, he says.
“It means you don’t have to put the energy storage onboard,” he says. “What we like about this mechanism is that you can take the energy, at least in part, from the environment.”

How UAE Produce Is Taking Over The Dining Table: 'We Are Growing All This On Our Doorstep'
Local farms are reporting a rise in demand, while Atlantis, The Palm resort has introduced an initiative to put UAE produce on its restaurants' tables

The concept of a “farm tour” is not what it once was.
Instead of the smell of open mud and fertilizer that I used to equate with a farm, I’m standing inside a pristine, temperature-controlled room that contains rows of herbs and leafy greens stretching out to the ceiling.
I am at Oasis Greens, one of many hydroponic, vertical farms to have cropped up in Dubai over the past few years. In this high-tech environment, seeds are planted into foam, which is placed in a solution that provides plants with all the nutrients they need, while LED lights overhead mimic the rays of the run.
The process involves no messy soil or pests and, by default, no need for pesticides either, while 90 percent less water is used than required by traditional farms. The result is sustainably grown, organic and local produce – from varieties of lettuce (be it butterheads and icebergs) to kale, rocket, and bok choy.

Whether it’s a hydroponic or traditional farm, there are indisputable benefits of opting for local over imported produce, which is being noticed by both consumers and big brands.
Among the latter is Atlantis, The Palm, which has launched a sustainability initiative titled the Atlantis Atlas Project.
One of the cornerstones of this campaign is a pledge to give diners access to dishes that are made with locally sourced and organic ingredients, grown and harvested in the UAE. Kelly Timmins, director of conservation, education and corporate social responsibility at the hotel, says the reason for this is two-fold.
“One of the key focuses for Atlantis is to look at increasing our use of local suppliers and vendors as part of our commitment to drive the whole local economy."
She says using local produce is better for the environment as it reduces freight and the carbon footprint involved with bringing in goods from across the world.

“We are trying to see how we can source perishable products responsibly. Sustainability is a journey and to get there we need the involvement of our community,” she explains.
To procure fresh ingredients on a daily basis, Atlantis, The Palm has teamed up with Fresh on Table, which works as a facilitator between UAE farms and consumers. The company, which launched in Dubai in 2019, takes orders from hotels, stores and customers online, and co-ordinates with farms to ensure that the product is harvested, packaged and delivered the next day.
According to commercial manager Garima Gambhir, the company has grown month-on-month, and currently works with more than 1,000 farms, as well as big hotel groups.

“Chefs realise that local produce is just fresher and going to last longer on the shelf, as opposed to something that has, say, been imported from [the Netherlands] and passed through three days of transit before reaching the kitchen,” she says.
The pandemic has also had an invariable role to play in the rising demand for local produce.
“When borders and hotels started closing last year, the supply food chain was disrupted. With distributors unable to fulfil contracts from international suppliers, we were able to pitch in because everything was local, reliable, and could be picked up from a farm and delivered in a few hours,” says Gambhir.

Local farms have also witnessed a spike in demand over the past year. Nikita Patel, founder of Oasis Greens, says despite the pandemic, business has been good, with a notable rise in online orders.
“Everyone has been at home, cooking. And even though we didn’t have a lot of tourists come in, residents weren’t leaving, either,” she says.
“I think the pandemic made people realise that food security isn’t a theoretical thing. In a lot of countries, people were having issues with grocery items running out, but the UAE did a very good job ensuring that didn’t happen. Over the past year, more companies are looking inwards and seeing how they can source local. We are just riding the wave.”
Hydroponic farms in the UAE

Oasis Greens grows approximately 12 to 15 types of herbs and leafy greens, and has started cultivating microgreens. “The aim is to get into fruits and vegetables, too,” says Patel. “We want to grow cherry tomatoes, chillies and more.”
Within the industrial area of Al Quoz, meanwhile, grows one of the largest, most lush indoor vertical farms in the region. UNS Farms is home to 16 varieties of leafy greens and 16 varieties of micro greens across a space of 5,600 square metres.
During a tour, executive director Mehlam Murtaza asks us to dip our feet in a solution to ensure we don’t track any crop-destroying bacteria or germs inside, before explaining how different elements can affect the growth of plants.
“Our LED lights are a custom design with a special spectrum. Each colour actually has a different effect on the crop – they can widen the leaf size, make them longer or have another indirect effect,” he says.
The nutritional value of the plant remains unchanged, though, with a lot depending on the quality of the seeds used. The seed also plays a role in the taste – at USN Farms, I’m given two types of basil leaves, Thai and Italian. Despite the fact that both varieties are grown in the UAE, the Italian version is subtle in taste and smell, while the Thai is sharper.

“We have just scratched the surface about what we can do,” says Murtaza. In the future, research and development may be able to further tweak the taste of plants, he adds. "Who knows what's next? Maybe cotton-candy-flavoured herbs."
With a number of perks of buying local, it does beg the question: why haven’t hotels been doing this all along?
Murtaza says it’s only in the past couple of years that vertical farms have developed to deal with the volume they need. Even then, the maintenance and power required to run hydroponic farms means only certain crops can be grown at financially feasible rates.
Locally 'farmed' seafood in the UAE

Supporting local goes beyond leafy greens. While the UAE is blessed with an abundance of seafood, there is still a reliance on imports.
That's something home-grown company Fish Farm is aiming to change. Launched in 2013, the company identified the most in-demand fish species being imported and sought to change this by growing them within the country. It currently produces organic and regular salmon, sea bass, sea bream, yellowtail kingfish, and hammour.
“It’s all part of building our food security,” says chief executive Bader bin Mubarak. “At the moment, less than 10 percent of the fish is locally acquired. We want to be able to cover the entire UAE market.”
The company plans on doing this with the help of three facilities: a caged farming facility in Dibba, a hatchery in Umm Al Quwain, and a land farming facility in Jebel Ali.
At the facility in Jebel Ali, Mubarak explains how juveniles and eggs were first sourced from different parts of the globe to ensure the right genetics.
“But since then, we have been hatching our own fish eggs,” he says. The Fish Farm was the first establishment in the world to grow Atlantic salmon on land, from eggs, Mubarak says.

Business development manager Edmund Broad agrees that it is all about growing and harvesting seafood in the most sustainable manner possible.
“One of the biggest problems with the seafood industry is the pressure it puts on wild fish stocks, through commercial hunting using huge nets. We are a substitute for this. By growing fish on land in a controlled and secure environment, we are not taking anything from the sea. We’re leaving the oceans alone.”
The farm has recreated the ideal environments required by fish, many of which stem from cold-water countries, such as Scotland and Iceland. The fish swim in an area with appropriate salinity, currents, temperature, pH level, and even lighting.
“We’ve recreated the ideal marine conditions suitable to each species: the Atlantic for the salmon, the Pacific for the yellowtail kingfish, the Gulf for the hammour and the Mediterranean for the sea bass,” explains Broad.
The farm currently produces 3,000 metric tonnes of fish per year. “By 2030, we want 50 per cent of seafood consumed to be produced within the country,” says Broad.
From farm to table
UAE residents can get a taste of these sustainable and local ingredients in some of the best restaurants in the country. Thanks to its sustainability pledge, nine of Atlantis, The Palm's signature restaurants are serving dishes with ingredients grown and harvested in Dubai.

Guests can tuck into locally produced burrata from Bread Street Kitchen or an organic salmon carpaccio from Seafire Steakhouse. Hakkasan is offering dim sum with locally handpicked chestnut mushrooms while Nobu has a crispy hand-picked shiitake mushroom truffle salad.
Ronda Locatelli, The Shore, Wavehouse, and White Restaurant are some other restaurants offering dishes with sustainable ingredients.

Raymond Wong, chef de cuisine at Seafire Steakhouse, says the difference between imported and local ingredients is staggering.
“As a chef, an import order is always challenging as you need to place it three to four days in advance for your produce to come in time. But with this initiative, we can order just a day in advance from sustainable farms in Dubai and the produce is as fresh as it can be.”
He hopes this will encourage other restaurants and hotels to follow suit. “I think it will bring a lot of awareness. A lot of people don’t even know we are growing all this on our doorstep.”

Source: RotoGro
RotoGro (RGI) provides an update of its vertical farming technology with encouraging results from recent trials
The company says recent data indicates its garden systems produce more yield per square meter when compared to other indoor vertical farming methods
Further, trials of RotoGro 710 are said to be progressing well and the team is trialing how to further reduce water and energy usage
RGI is also encouraged by its studies and customer feedback for its RotoGro 420 system which it says validates commercial-scale cultivation of lawful cannabis
Shares were trading 2.3 percent higher at 4.4 cents apiece
RotoGro designs and manufactures cultivation solutions for indoor vertical farming, operating in perishable foods and lawful cannabis.
The RotoGro Garden System is the core of the company's technology with the ability to maximize plant surface growing area by situating a spherical garden around a centrally placed lighting system.
The systems can be stacked, maximizing the yields per square meter when compared to the ground space occupied.
RGI said data collected from recent crop trials conducted in collaboration with agriculture company Verity Greens and herb grower and distributor Fresh Leaf indicates its garden systems produce more yield per square meter when compared to other indoor vertical farming methods.
Specifically, RotoGro projects yields 3.8 to 15.3 times the yield per square meter compared to industry-leading farming producers and greater in contrast to greenhouse and conventional farming.
CEO Michael Di Tommaso said ventures like the ones with Verity Greens and Fresh Leaf will "strengthen RotoGro’s market presence by successfully penetrating the burgeoning indoor vertical farming industry with its technology offerings".
Further, internal trials of the company's most recently developed garden system, the RotoGro 710, are said to be progressing well with cultivation of 48 kilograms of basil and 26.5 kilograms of cilantro in a single harvest cycle.
After multiple trials cultivating leafy greens, the agronomy team repeatedly achieved yields of 124 kilograms in a fully planted RotoGro 710, indicating single harvest yields of 372 kilograms could be achieved when the technology is at full capacity, stacked three-high.
The team is trialing shorter full crop cycle lengths while maintaining yields and aims to refine the plant irrigation schedules to further minimize water usage and refine the environmental controls to ensure enhanced energy efficiencies.
In other news, RotoGro has enabled full automation of its lawful cannabis cultivator, RotoGro 420.
The company's software controls the wheel revolution speed, lighting cycles, and spectrum variations, direct CO2 injection as well as the plant irrigation processes and environmental controls including temperature, air conditioning, and humidification.
Notably, the 420-garden system has been able to consistently produce 10.2 kilograms of dried cannabis flower in a single 56-day crop cycle when stacked three-high.
RGI said its studies in combination with its customer’s data validates the commercial viability of RotoGro 420 in the commercial-scale cultivation of lawful
cannabis.
Mr Di Tommaso said RotoGro is continuing to develop relationships globally to expand its presence in both the perishable foods and lawful cannabis markets.
Shares were trading 2.3 percent higher at 4.4 cents apiece at 1:31 pm AEST.
