Local Company Providing Fresh Produce, Tools to Grow It All Year Long
Since opening its doors last July, Cold Acre Food Systems has been perfecting its indoor hydroponic growing systems for greens and herbs that can be harvested continually throughout the year.

The Yukon isn’t the place in the world most suited to year-round farming, given its long winters and short, unpredictable summers, but one local company is trying to change that.
Since opening its doors last July, Cold Acre Food Systems has been perfecting its indoor hydroponic growing systems for greens and herbs that can be harvested continually throughout the year.“
Hydroponics is a very old growing system and can be done in different methods,” said Carl Burgess, Cold Acre Food Systems CEO. “It’s essentially nutrient water delivered to roots to grow plants.”
The benefit of it in food production for a community sense is that there is less soil management because there is no soil management and in that way it can stabilize production year-round,” Burgess added.
The company does the majority of its farming in two shipping container-style growing facilities located on Titanium Way in the Marwell industrial area.“
Right now we are operating 6,000 planting spaces,” Burgess said. “One of those (containers) is basically equivalent to an acre of a market garden,” and “one container can give, at minimum, a weekly supply of greens to about 100 to 200 people.”

Environmentally, the system uses 10 to 20 percent less water than the traditional method of growing, Burgess said. The carbon footprint is also greatly reduced since produce only has to travel a couple of blocks to its destination compared to being shipped on trucks, food waste is almost nonexistent because of the high reliability of growing indoors, the company uses compostable packaging, and there are no storage facilities.“
We harvest and go,” Burgess said. “It’s usually within two hours of harvesting that the produce is in the grocery stores or dropped off at someone’s home.”
What began as some test lettuce crops have turned into a diverse selection of leafy greens, like bok choy, arugula, kale, mizuna, and rainbow chard, as well as several different types of microgreens, which are similar to sprouts in appearance, and basil. The company is also experimenting with growing edible flowers and mushrooms.
Cold Acre Food Systems currently sells the vegetables it grows to several grocery stores in Whitehorse, restaurants, and cafes, and through a subscription box.“
The last year of business has been lots of fun,” Burgess said. “We went from being a very small food producer to a medium-sized food producer (in the Yukon).”
But selling the vegetables it grows isn’t the end game for this company. Building, selling, and installing growing systems is also part of Cold Acre’s business model. The company can build custom growing facilities for just about any client, from smaller at-home units to the larger commercial shipping container-style units.
Right now there are two large units that will soon be providing fresh produce to Yukon communities. The first, in partnership with the University of Calgary, is at the Kluane Lake Research Station near Silver City. Once it is up and running it will provide food to the Haines Junction and Burwash Landing areas. The second, currently still in Whitehorse, is owned by Na-Cho Nyäk Dun Development Corporation (NNDDC) and will be ready to feed people in the Mayo area this spring.

We are currently fabricating a small-scale unit for demonstration/growing inside the Mayo Foods Store as part of the NNDDC project,” said Burgess.
The objective of Cold Acre Food Systems is to reduce food scarcity in the North and to enable everyone access to fresh produce year-round. “Success will be twofold,” said Burgess. “Our goal is to activate indoor growing. So success will look like a handful of growing facilities around that we either deployed or helped deploy. And success for us looks like a large growing facility that’s displacing a number of food products that right now are coming up the road and doing that cost effectively for consumers.”

Is The Future of Farming Indoors?
The global population is predicted to reach 9.7 billion by 2050, and to feed everyone, it’s estimated that global food production will need to increase by up to 70% in the next 30 years

I write about sustainable and ethical technology and consumer trends.
The global population is predicted to reach 9.7 billion by 2050 and to feed everyone, it’s estimated that global food production will need to increase by up to 70% in the next 30 years.
There are many challenges to overcome before fears of a worldwide food shortage can be allayed, including rising temperatures and more frequent droughts caused by global warming. These obstacles are making traditional farming methods increasingly inefficient and unpredictable.
Traditional farming has also been hit hard by the COVID-19 pandemic. According to the FAO, border closures, quarantines and disruptions to supply chains are limiting some people's access to food, especially in countries hit hard by the virus or already affected by high levels of food insecurity.
There’s an emerging consensus that the agriculture industry needs to adapt to use less water and chemicals, make crops less vulnerable to changes in the climate, and produce more reliable yields. Part of the answer may lie in the emerging start-ups growing produce in indoor environments, where growing conditions can be better managed.
The indoor farming technology market was valued at $23.75 billion in 2016, and is projected to reach $40.25 billion by 2022. Yields are typically much higher than traditional farming methods. Crops from indoor farming are grown in three dimensions, rather than two – and can be grown all year round, independent of external weather conditions.

One of Square Roots’ indoor farms, for example, produces the same amount of food as a two- or three-acre farm annually, just from 340 square feet. This yield is achieved by growing plants at 90 degrees, and by using artificial intelligence (AI) to ensure the environment is optimal for each specific plant, including the day and night temperatures and amount of CO2 needed.
“Our indoor farms are living biosystems, constantly adapting to maintain optimal climates for growing specific crops. We’re then able to understand how changes in the climate can impact yield taste and texture,” says Tobias Peggs, Square Roots’ chief executive.
Not only could indoor farming help adapt to a warming planet, but it has the potential to help slow down climate change by being more sustainable – using less water and producing fewer emissions. While estimates vary widely, according to the United States Environmental Protection Agency, agriculture accounted for 10% of all greenhouse gas emissions in 2018; it is also highly dependent on, and a pollutant of, water.
Square Roots’ pop-up farms are built in shipping containers in cities, often in parking lots. They serve local communities, which means reduced emissions compared to traditional agriculture, which often involves transporting food much further. For example, it has 10 farms in Brooklyn that serve 100 retail stores all within five miles of the farm.
At the Plenty headquarters in South San Francisco, leafy greens use up one percent of the land and five percent of the water compared to traditional outdoor farms, says Matt Barnard, the start-up’s Chief Executive Officer, and Co-Founder.
AeroFarms’ indoor farm in New Jersey grows greens including baby kale, baby arugula, and baby watercress using 95% less water than conventional agriculture on just one percent of the land required. The crops grow under LED light with no pesticides and a fraction of the fertilizer used on traditional farms.

Marketing director Alina Zolotareva says being able to produce have ready-to-eat produce that doesn’t require rinsing helps to reduce water usage.
“This is a transformational innovation for agriculture at large,” she says, “as access to fresh water for growing food is one of the most pressing challenges of our time.”
As well as fewer miles and less water, indoor farming doesn’t require pesticides. This is better for the environment and human health as it eliminates the risk of water contamination due to run-off, and is in line with increasing consumer demand for non-GMO produce.
Plenty eliminates the need for pesticides with LED lights, which are synced with the crop’s growth, Barnard says, to provide the ideal spectrums and exposure and minimize energy usage.
“Our sensor system ensures each plant gets exactly the amount of purified water it needs, and any excess water is recycled through a closed-loop irrigation system resulting in greatly reduced water consumption and zero waste,” he says.

MOLEAER
Other farms are using nanobubble technology, such as Moleaer, which has allowed more than 100 indoor farms to connect their irrigation systems to generators that provide oxygen via sub-micron gas-containing cavities to the plant’s roots to provide chemical-free water. These nanobubbles result in healthier roots, more resilient plants, and increasing crop yields, says Nick Dyner, CEO of Moleaer.
“Our oxygen transfer efficiency provides the most cost-effective solution to elevate oxygen levels in the water, which in turn promotes beneficial bacteria and root development,” he says.
The company is also working on a new NASA-approved space farming research project, exploring how astronauts on the International Space Station can grow their own food in microgravity using nanobubble technology.
There are concerns that it’s an expensive investment, but Dyner says Moleaer has various systems so it’s accessible to all sizes of indoor farms, high- and low-tech. Some products do, however, require growers to connect an external source of oxygen, which must come from a gas supply company or an onsite oxygen generator, which Moleaer provides.
“In many cases, traditional farmers may have more to gain by using our technology, since the capital investment is significantly less than the most advanced growing technologies available today, which are often out of a typical farmer’s budget,” Dyner says.
“Nanobubble technology is a cost-effective, chemical-free, and scalable solution that allows growers to increase crop yields and shorten cultivation time - which will be much needed to feed our growing population in the future.”
Peggs says Square Roots is also focused on ensuring its technology makes farming an accessible career path for young people who live in urban areas.
“If you’re a new young farmer at Square Roots, our app will guide you through what to do; what’s growing, what state is in it, what do we need to do today based on where things are in the growth cycle. Through our app and our training program we’re able to bring new people into our team, even folks with zero horticulture experience, and get them ready to go in about six weeks.”
Indoor farming is putting the youth back in agriculture. PLENTY
But despite being an emerging option for youth in the city, Barnard predicts most will remain traditional farmers.
“The world still needs the field and will need the field forever. We support the field by growing in addition to the field. Over time, [indoor] farming systems will become more accessible and affordable. Both field and indoor farming will be necessary to support global food demand.”
Viraj Puri, Co-Founder, and CEO of Gotham Greens, a pioneer in urban indoor agriculture that operates over 500,000 square feet greenhouses in 5 U.S. states, echoes this sentiment: “Growing produce indoors certainly has an increasing role to play in the future of sustainable food production. While indoor farming may not represent the future of all fresh produce production, for certain types of crops such as tomatoes, cucumbers, leafy greens, and herbs, it will become more prevalent. Customers are increasingly recognizing the reliability, consistency, and high quality of greenhouse-grown produce that’s grown in close proximity to large population centers using fewer natural resources. Other agricultural commodities like grains or fruits or root vegetables, however, can’t yet be produced.”
However, Dyner predicts that, eventually, the majority of agriculture will move to indoors, in vertical farms— the practice of growing crops in vertically stacked layers—in urban areas.
“These settings enable traditional farming to shift to controlled growing conditions, using new technology and automation, and reducing the risk of exposure to harsh climate conditions,” he says.

PLENTY
Start-ups like Square Roots, Plenty, and AeroFarms currently practice vertical farming, which is a form of indoor farming that relies on artificial lighting such as LEDs instead of drawing on natural sunlight.
Other indoor farming companies like Gotham Greens grow produce in high-tech glass-clad greenhouses that primarily rely on natural sunlight for plant photosynthesis. According to Puri: “vertical farming is a more nascent technology within the indoor farming sector and the costs of running a vertical farm with artificial lighting and air conditioning is currently not as cost-effective as relying on natural sunlight in greenhouses.”
Gotham Greens takes a different approach, relying on natural sunlight rather than the artificial ... [+]
GOTHAM GREENS AND JULIE MCMAHON
“Greenhouse indoor farming technology has been in operation globally for 20 to 30 years and is proven to be commercially viable. That being said, the costs around artificial lighting and other vertical farming technologies have been coming down significantly in the past few years,” he adds.
Nonetheless, indoor farm technology start-ups, broadly speaking, don’t see themselves as disruptive, but as being on the same side of traditional farms, for the wider cause.
“The common enemy is the industrial food system, shipping food from one part of the world to the other, rather than locally produced food,” Peggs says.
Indoor farms don’t work in competition with each other, either; they work collaboratively by forming a network that shares data. For example, AeroFarms is collecting data on a research project with the non-profit Foundation for Food & Agriculture Research to understand the sensory and nutritional characteristics of leafy greens for the benefit of the entire agriculture industry.
However traditional and AI-based indoor farming work together in the future, there’s little doubt that indoor farming is helping to meet the needs of a growing global population and support traditional farming, which is both at the mercy of and exacerbating a warming planet. Only one method will find itself in space – but there’s space for them both.

Farm to Fork: This Millennial Urban Farmer Grows Vegetables On Carpark Rooftops in Singapore
The ongoing battle against the COVID-19 outbreak and the resultant lockdowns imposed in many countries worldwide have put the spotlight on Singapore’s dependence on food imports and its vulnerability to global supply shocks.
Singapore Announced New Measures in April Aimed At Speeding Up Local Food Production Over The Next Six Months To Two Years.
By Vulcan Post
June 25, 2020
The ongoing battle against the COVID-19 outbreak and the resultant lockdowns imposed in many countries worldwide have put the spotlight on Singapore’s dependence on food imports and its vulnerability to global supply shocks.
The government has repeatedly assured its citizens that Singapore has sufficient food supplies, amid bouts of panic buying that gripped the country when Singapore raised the DORSCON level to Orange.
Although the panic buying has now eased, another cause for concern is that Singapore has a population of about 5.7 million people but it only produces about 10% of its food needs.
To tackle this food crisis, Singapore announced new measures in April aimed at speeding up local food production over the next six months to two years.
This includes providing a SGD 30 million grant to support production of eggs, leafy vegetables, and fish in the shortest time possible, and identifying alternative farming spaces, such as industrial areas and vacant sites.
As part of that project, the Singapore Food Agency (SFA) and the Housing Development Board (HDB) have launched a tender in May for rooftop farms on public housing car parks.
This means that the rooftops of a handful of multi-story carparks in Singapore will be converted for use to farm vegetables and other food crops from the later part of this year.
Farming hits the roof
The move to find alternative farming space in land-constrained Singapore is part of their strategy to meet the country’s 30 by 30 goal, which is to produce 30% of its nutritional needs locally by 2030.
Local agritech startup Citiponics did not take part in the tender this time round, though it piloted SFA’s multi-story carpark rooftop farm project in Ang Mo Kio last year.
According to Danielle Chan, co-founder of Citiponics, its 1,800 square metres farm atop the carpark at Block 700 in Ang Mo Kio Avenue 6 can grow between three and four tonnes of vegetables a month.
They grow up to 25 different types of vegetables naturally without the use of pesticides.
“We currently specialize in growing our own crossbreed of lettuces—Georgina Lettuces—and have also been growing other varieties such as nai bai, Italian basil, and Thai basil based on customers’ requests,” said Danielle.
Sharing more about the Ang Mo Kio site, she said they have been steadily producing pesticide-free vegetables on a monthly basis, supplying to nearby residents and consumers islandwide.

Beyond contributing to local food production, this pilot project has also generated “positivity,” which stems from community involvement when visitors get to know and see their food source.
“It brings us great joy to see the senior citizens enjoying their time as they work on farming activities as well as the support we have received from visitors who come to our community markets to self-harvest their produce,” said Danielle.
She added that they hire senior citizens from AWWA Community Home as well as part-time workers to help with farm maintenance.
“We believe that even if one does not have the technical agriculture know-how, they should be able to contribute to food production as well.”
Citiponics is a Singapore-grown urban farming company that started in 2016, which aims to grow safe produce through its zero-waste farming process.
It is co-founded by Danielle and her family friend Teo Hwa Kok, who has a “rich experience in agriculture.”
When agriculture meets tech
The 26-year-old is a National University of Singapore (NUS) graduate, who has worked in technology startups across Singapore and New York, as well as technology consulting companies such as IBM.
But with her tech background, why did she choose to be a ‘farmer’?
“I grew up in an agricultural environment and as such, the farm was always my playground. Growing up, I never had to worry about buying vegetables from the supermarket or doubting my food source. I had the blessing of getting all my vegetables supplies directly from the farm,” explained Danielle.
“Having personally witnessed the wastage as well as the inefficiencies in the traditional farming industry, I knew I wanted to go back to the farming industry to change the way farming is done traditionally as well as to share the blessing of the farm-to-table experience with others.”
Her tech background didn’t go to waste though. She made it a point to integrate technology into Citiponic’s farming processes.

They have a proprietary vertical farming technology called Aqua-Organic System (AOS). It falls under a solid-based soilless culture, which is different from the likes of traditional farming and hydroponic farming system.
As every drop of water is kept in a close loop within the growing system, it helps to minimize water consumption, using one-tenth of hydroponics water consumption and one-hundredth of traditional farming water consumption.
Due to its vertical nature, it is also able to be seven times more productive than traditional farming.
As it is specially designed to provide a natural farming environment in order to preserve the nutrients value and natural taste of the vegetables, the technology is also pollutant-free and pesticide-free. It’s also anti-mosquito breeding, which makes it very suitable for farming within community and neighborhood areas.
“The AOS farming technology removes the complex technicalities of farming and we wanted to keep it that way to allow people of all ages and backgrounds to have a great experience when they get to farm with our systems,” said Danielle.
COVID-19 does not pose a huge business challenge
All of Citiponic’s farmed produce are segmented to home deliveries, nearby residents, and selected NTUC FairPrice outlets.
Despite their limited farming space, Danielle said that they see a constant stream of supply and sales.
It’s not so much a business challenge, she added, but the need to adapt to the new normal, hence the introduction of home deliveries and engaged logistics channel.
Although COVID-19 does not greatly impact its business, it serves as a timely reminder on the importance of accelerating our local food production.
This pandemic serves a time for us to reflect on how we can enhance our food resilience strategies.
Singapore steps up to be more food resilient
As Singapore is still largely dependent on food imports, the rooftop farming tender and local food production grants are definitely the right steps forward.
According to SFA, Singapore currently secures food supply from about 170 countries.
For instance, Singapore now imports oranges from Egypt, milk powder from Uruguay, eggs from Poland and shrimps from Saudi Arabia as part of its efforts to broaden food supplies.
Danielle is well-aware that food security, food sustainability and food safety are global issues, so she hopes to bring Citiponics’ farming solution to more countries.

“We are not only focused on food production, but also becoming an agritech solution provider. We have developed agriculture technology and designed farming solutions that are suitable for tropical countries, and hope to extend the applicability of our expertise and farming technology to temperate countries as well,” she added.
Citiponics is also looking at scaling its operations to enhance its contribution to local food resilience and grow more communities through the introduction of hyperlocal Citiponics urban vertical farms in various neighborhoods of Singapore.
“We envision Citiponics as a supportive environment that is able to cultivate the next generation of urban farmers and agritech innovators.”
