Harvesting Microgreens 101: What You Need to Know
Learning when to harvest microgreens is an essential step to the growing process. Since these tiny leafy vegetables tend to grow fast, it’s critical to know when to harvest them
Learning when to harvest microgreens is an essential step to the growing process. Since these tiny leafy vegetables tend to grow fast, it’s critical to know when to harvest them. In this article, we’re going to cover everything there is to know about harvesting microgreens.
Harvesting Microgreens
You can harvest the microgreens during two stages of their growth. Once the seedlings start to grow, you’ll notice the first leaf or pair of leaves which are known as cotyledons. You can harvest your microgreens during this stage, or you can wait until they grow their next set of leaves, which are known as true leaves.
It’s essential to harvest your greens during either of these stages, which can happen within the first two weeks. If you wait too long to harvest, they will start to yellow or have stunted growth. Signs of plant stress can happen from several factors such as soil quality, plant species, and more. This is why it’s best to harvest your microgreens when the cotyledons or true leaves appear.
How to Harvest Your Microgreens
The best times to harvest your microgreens are during the early morning or evening. If you harvest during these times, your microgreens are more likely to be fresh and healthy.
When harvesting microgreens, you’ll need a pair of scissors. Your microgreens should range from about 1 to 4 inches in length. Make sure to cut your microgreens about an inch above the soil. After trimming, wash the ends to remove any unwanted soil or dirt. If you are not cutting above the cotyledons, then the microgreens will not grow any further. You can compost the tray after you’re done harvesting the microgreens.
Washing and Drying
Depending on how you’re growing your microgreens will determine how you’ll wash them. If you’re growing them in soil, it’s recommended to wash the ends to rid them of any leftover soil or dirt so it won’t ruin the taste of your food. However, if your microgreens are growing from other methods, you won’t have to wash them. It’s best to wash your microgreens in cold water to maintain overall freshness. Make sure to remove damaged leaves or other problem areas to avoid an undesirable taste.
Drying your greens is an easy and simple process. Layout the greens in front of a fan and let them dry for a few minutes, and turn them over every so often to ensure they dry completely.
Storing Microgreens
Stored microgreens can last up to several days in the refrigerator. To correctly store your plants, we suggest placing them between paper towers inside a food grade container. This can help extend their shelf life for up to a week or two.
Harvesting microgreens is a simple and easy-to-understand process. Once you’ve harvested your greens, have fun adding them to your salads or dishes of any kind!

US: MAINE - Vertical Greenhouse Coming to Westbrook
The City of Westbrook will soon be growing produce a little differently. Starting in the spring of 2021, a company called Vertical Harvest will begin building a vertical greenhouse on Mechanic Street
29-07-2020 | News Center Maine
US- A 70,000 square-ft vertical greenhouse will produce 1 million pounds of produce per year to the city and surrounding areas.
The City of Westbrook will soon be growing produce a little differently. Starting in the spring of 2021, a company called Vertical Harvest will begin building a vertical greenhouse on Mechanic Street.
The planned 70,000 square ft facility will initially grow a variety of microgreens and lettuce. The company estimates the greenhouse will produce 1 million pounds of produce per year to the city and surrounding areas.
Westbrook will be the company’s second location in the United States. The co-founder said she came up with the vertical idea after realizing the need for fresh produce year-round in an urban setting.
“We want to grow as much food as possible. We want to employ as many people as possible. We want to do both year-round. That’s what gave us the idea to go up. So at its heart, we want to be able for these farms to serve the community in which it sits, so that means being in the heart of our urban centers,” said co-founder Nona Yehia.
Yehia said the greenhouse will bring 50 full-time equivalent jobs to the city. The mayor of Westbrook said the greenhouse is part of a larger project, which will include a parking garage and new apartments.
A documentary about Vertical Harvest called Hearts of Glass was recently released.
Here’s an excerpt from the film.

5 Benefits of Microgreens That Will Boost Your Health
Microgreens are the powerhouse of nutritious foods. These functional foods are the seedlings of vegetables or herbs and are known to boost health function and prevent disease
Microgreens are the powerhouse of nutritious foods. These functional foods are the seedlings of vegetables or herbs and are known to boost health function and prevent disease. Known as being tiny vegetables, microgreens are great additions to any dish as they provide texture, various flavors, and are packed with nutrients. In this article, we’re going to cover five benefits of microgreens that are beneficial to your health.
Nutrient Rich
Studies have shown that microgreens tend to have nine times the amount of nutrients than their mature counterparts. In this study that was published in the Journal of Agricultural and Food Chemistry, it states that “microgreens contain considerably higher concentrations of vitamins and carotenoids than their mature plant counterparts.” By being rich in nutrients with great taste, it’s no wonder these tiny vegetables are growing in popularity.
Prevents Diseases
Not only are they rich in nutrients, studies have shown that microgreens are also filled with antioxidants. Antioxidants can help prevent diseases by removing free radicals from the body. Free radicals are unstable waste molecules that accumulate from factors such as pollution or natural bodily processes. But, as these unstable molecules build, they can develop diseases such as cancer. Intaking foods high in antioxidants can help increase your chances of preventing diseases since they help remove unstable molecules from the body.
Free From Pesticides
Since microgreens are easy to grow indoors, growers will always know what’s going on with their food. This means that microgreens won’t have to be sprayed with pesticides and that they’ll be eaten fresh. These tiny plants can grow in 1-2 weeks and are easy to harvest. Now, we can take comfort in knowing that our homegrown microgreens are free from pesticides and any other harmful chemicals that other crops fall victim to.
Sustainable Source
Since microgreens are easy to grow indoors, city dense populations could take advantage of growing these healthy-packed foods at home. With a turnaround time of a few weeks to full growth, people will always have access to fresh, nutrient-dense foods. To create an ongoing source of microgreens, you could rotate a few crops at the same time, so you’ll always have something fresh to eat per week. This could be a life-changing method for low-income families to get healthy vegetables at a low cost on a consistent basis.
Reduce Risk for Heart Disease
One of the benefits of microgreens is that they have the potential to lower blood pressure, which is one of the major risk factors for heart disease. Since these special vegetables are rich with fiber and vitamin K, eating them on a daily basis can lower your risk to develop heart disease.
The benefits of microgreens are endless. We at the Nick Greens Grow Team understand the nutritional and life-saving benefits behind these magical plants. The time to start learning how to grow your own microgreens is now.

VIDEO: Dubai’s Badia is GCC’s First Commercial Vertical Indoor Farm
Badia Farms in Al Quoz Industrial area in Dubai is the GCC’s first commercial vertical indoor farm that supports Dubai’s agricultural sustainability
June 26, 2020
An expert takes notes on the health of vegetables.
Gulf Today, Staff Reporter
Badia Farms in Al Quoz Industrial area in Dubai is the GCC’s first commercial vertical indoor farm that supports Dubai’s agricultural sustainability.
The large-scale high-tech vertical farm produces 3,500kg of chemical, pesticide, and herbicide-free fruits and vegetables per year.
Badia Farms said, “We have a growing reputation for supplying the finest micro-greens and herbs to Dubai’s top restaurants, caterers and chefs.”
Vertical farming is the practice of producing food vertically in stacked layers, vertically inclined surfaces, and/or integrated in other structures.
It uses a combination of indoor farming techniques and controlled-environment agriculture (CEA) technology.
Experts examine a produce.
Vertical farms can grow non-native produce in locations where traditional agricultural methods are impossible. Also, there’s no exposure to the hazards of traditional farming, such as bugs, diseases, pesticides and weather.
In some ways, it’s as simple as it sounds: a vertical farm is a multi-story greenhouse where fruit and vegetables are grown in stacked up towers. There’s obviously a lot more to it than that – and here’s where we’ll try not to blind you with science.
The techy term for it all is hydroponics, which is a technique for growing produce without soil. Seeds are planted in a sterile, soil-less growing environment and then grown in nutrient-rich water. Water is recycled, and everything from air and water temperature through to humidity and lighting are controlled to create the perfect growing environment.

Microgreens Launched By Vertical Farmer April Sun
Just in time for this year’s winter season, vertical farmer April Sun launched its range of sustainably grown microgreens from its new commercial-sized micro-farming facility in Melbourne
Food & Beverage | June 4, 2020
Just in time for this year’s winter season, vertical farmer April Sun launched its range of sustainably grown microgreens from its new commercial-sized micro-farming facility in Melbourne.
With a philosophy of true sustainability and paired with cutting-edge technology, the local farm wants to provide the community with a range of nutrient-packed microgreens available year-round to their nearby community.
Co-founder Darren Nichol, April Sun visionary of Australia’s cleanest and highest nutritional food supply who has a wealth of knowledge due to his agricultural background, says, “This is a particular focus of the Darebin Council. They have an actual goal to increase food production within its municipality.”
These super foods are grown without pesticides and utilise 95 percent less water than traditional farming methods due to a hydroponic based (closed loop) watering system. Co-founder Ty Dickson, April Sun technologist and facility designer, said this system guarantees the plants do not receive too little or too much water.
“The watering targets each individual plant or root system and is drained back to the holding tanks,” he said. “Traditional farming methods would see water being lost to the ground and you would use more water to achieve the same level of fertigation without the ability to recapture the excess.”
With custom-spectrum lights developed in-house, the microgreens are grown in their ideal conditions, allowing for year-round production and minimal waste.
“We use a combination of specific wavelengths of blue, red, far red and full spectrum light to stimulate the chlorophyll A and B of the plants, while giving the right signals to ensure proper colour, increased nutrients through stress and, above all, a very healthy plant,” Dickson said.
“We are a non-single use plastics company; we opt for PLA compostable packaging. Our facility uses the highest efficiency components and equipment available. We do run on electricity, although we are engaging in using 100% renewables, and are in preliminary talks with the Darebin Council to implement 100kW of solar panels on our warehouse roof.” said Dickson.
In traditional farming, external factors such as drought, pollution, soil erosion and more can impact crop success. However, the world of vertical farming is “most often done indoors in a controlled environment”, he adds. “Vertical farming when done sustainably has less impact on the environment, there are significant reductions in water usage, land usage, gas usage and many other resources. This is all achieved whilst controlling the indoor growing environment with minimal impact to it outside.”
“By controlling every factor in the plant’s environment, you end up with a high-quality product on a number of levels,” said Nichol.
“We can grow to a timeline and the removal of variables such as the weather allows us to more accurately forecast and grow to our customers’ demands. This can reduce the amount of waste and also increase consistency of supply to customers. This is a huge problem for traditional farming and is the cause for the large price jumps and shortages of produce on the market.”

Pros and Cons of Vertical Farming Systems: What You Need to Know
When you live in the city, there isn’t room for fields and fields of farmland. So, vertical farming systems allow for urban areas to organically grow their own food without taking up too much space
As urban areas become more populated, cities need to turn to vertical farming methods as the primary way of growing food. Vertical farming systems allow cities to grow microgreens, vegetables, and fruits in small contained spaces.
When you live in the city, there isn’t room for fields and fields of farmland. So, vertical farming systems allow for urban areas to organically grow their own food without taking up too much space.
But, what are the pros and cons of vertical farming? We’ll cover everything you need to know in this article.
What are the advantages of vertical farming systems?
There are plenty of advantages to vertical farming. Some of the main advantages include:
Year-Round Yields: When you grow crops with vertical farming methods, you will have year-round grows. Since the crops are grown in a controlled environment, they are able to keep growing throughout every season.
Weather Resistant: Crops grown indoors aren’t susceptible to damage by flooding, droughts, or pests! One of the main reasons as to why vertical farming works is that farmers can have full control of the environment.
Produces Organic Foods: Vertical farming systems promote the growth of organic, healthy foods. You don’t have to use pesticides, herbicides, or fertilizers to grow plants.
Leaves a Smaller Footprint: Vertical farming uses upward growth methods to harvest crops in small settings. These methods use less land to grow foods, which allows farmlands to their natural habitat.
What are the disadvantages of vertical farming?
While there are many advantages to vertical farming, we still have to understand the disadvantages. There are a few cons that come with these intricate systems.
They're Pricey: To start, vertical farming can be expensive in urban areas because of the construction and technology costs. This is why developers are reluctant to invest in vertical farming.
Requires Large Amounts of Electricity: In order to grow foods like grains, vegetables, or fruits, a lot of electricity is needed. We’ll have to rely on artificial lights to encourage growth, which can be expensive.
Can Lead to Potential Job Loss: As a new agricultural industry, vertical farming could replace a lot of traditional farming jobs. Food demands will be met by urban vertical farming, and the demand for traditional farmers could go down. This can result in a loss of jobs. But, it will also create new jobs within the city.
The Importance of Vertical Farming Systems
Vertical farming is a sustainable solution to growing foods within urban areas. As populations increase, food demands will rise. To meet these needs, we have to start implementing vertical farming systems to meet demands.
We at the Nick Greens Grow Team understand the importance of vertical farming, which is why we teach our followers how to successfully grow microgreens at home.

The Best Growing Mediums For Microgreens
Growing microgreens is an easy and sustainable process that you can do from the comfort of your home. You can grow all kinds of nutritious microgreens that will enhance the flavor of your foods
Growing microgreens is an easy and sustainable process that you can do from the comfort of your home. You can grow all kinds of nutritious microgreens that will enhance the flavor of your foods. These special vegetable-like plants grow from 1-3 inches and are vibrant additions to your foods. They are also jam-packed with vitamins and antioxidants. We're going to discuss the different growing mediums you can use for your microgreens.
Soil
Using soil as your growing medium is a popular and effective choice. Soil will provide you with the best yields over any other medium. We believe the Sunshine #4 by Sunshine Aggregate is the best, and the Black Gold Potting Mix is a close second. Each of these soils are extremely sterile, which is ideal for indoor growing. While these soils can cost more (about $1 per 10x20 tray), they provide the best results. But, don't worry. You can compost and sterilize your soil to re-use it for future grows.
Burlap
Burlap is another popular growing medium because it's cheap. For .25 cents a tray, you can't beat the price. It is made from the jute plant, which is used to make nets and ropes. But burlap is an incredibly difficult growing medium to use. The perfect growing conditions for burlap include 72 degrees Fahrenheit, 65% humidity, and a good micro-dose fertigation plan (fertilizer + irrigation). If you can populate these results, then you can achieve yields and results that match soil mixes.
But be mindful that this takes a lot of practice and time, which is why using burlap is better for expert growers. If you don't get the growing conditions right, then your yields will suffer. We recommend using larger seeds like Pea Shoots and Wheatgrass when using burlap. These seeds will thrive with a burlap growing medium, and you will get bountiful results.
Coco Coir
This growing medium comes from coconut fiber. It's perfect for holding in moisture and is difficult to over-water. It is cheaper than soil (about .60 cents a tray), but it's just as messy. Coco coir has a better yield average than burlap, about a 25% to 30% better average. You will find this growing medium in dehydrated blocks. When you add water, they will expand way past their original size. You can use coco coir with an ebb and flow hydroponic method.
Jute Pads
This growing medium is derived from jute fiber. It's able to transport water evenly through your microgreens and maintain a near-perfect water/air ratio. It holds in water very well, which means you'll have to feed your microgreens less. Kale and broccoli grow especially well in jute pads.
What's the Best Growing Medium?
This entirely depends on your growing intentions. What are you planning to grow and how much effort are you willing to put in? We're going to cover the main questions you should ask yourself that will help you make this decision.
Feeding Your Plants: If you want to water your plants by hand, then we recommend soil and coco coir. But if you're able to feed your plants on a timer, then go for burlap or jute pads. It can be a better option because it's cost-effective and can still get the job done.
Choosing Your Seeds: What kind of microgreens do you plan to grow? If you're growing broccoli or kale, then we recommend buying jute pads. Do you want to grow a wide variety of seeds? Then choose soil or coco coir as your growing medium.
Messy Vs. Clean: Do you hate cleaning up messes? Then it's best to steer clear of soil and coco coir. Go with jute pads since they're easy to handle and clean.
Choosing your growing medium ultimately boils down to what you're planning on growing and how much effort you want to exert. We hope this list helped you understand what kinds of growing mediums there are and how they can help you yield the best results.
We are the microgreen growing experts. We're even working with NASA to help figure out how to get microgreens safely into space for astronauts to use! We meet once a month to discuss a variety of topics about microgreens. So, keep reading our blogs and watching our informative YouTube videos. There will always be exciting news coming your way.

A High-Yield Indoor Farming System Ideal For The City
According to Pollard, the evolution of new technology, such as LED grow lighting and the Internet of Things (IoT), has complemented the development of indoor soilless cultivation systems
As prolonged droughts occur more frequently in South Africa, some entrepreneurs are investing in and developing new technology and farming methods, such as indoor growing systems, that ensure consistent, high-quality food production. Juan-Griffith Pollard, CEO of Urban Cultivation International, spoke to Pieter Dempsey about his scaleable hydroponic farming system.
More frequent and long-lived droughts. Global warming. Water scarcity. Higher input costs.
These are some of the factors driving the growing interest in new technology that enables a farmer to produce the same quality and yields as conventional farming, but using indoor farming systems instead.
Hydroponics, or indoor soilless cultivation, as Urban Cultivation International (UCI) calls it, is a method of growing plants in a water-based, mineral- and nutrient-rich solution instead of soil, and under artificial LED lights instead of sunshine.
According to Juan-Griffith Pollard, the CEO of UCI, indoor farming uses up to 90% less water than traditional farming practices, and far less space. In addition, plants can be grown pesticide-free and closer to high-consumption areas, such as densely populated cities.
These reasons, and more, explain why an increasing number of growers have begun exploring indoor soilless cultivation.
Precision growing
The system provides the optimal growing conditions for plants, enabling them to develop much faster and be far healthier than is the case with traditional outdoor cultivation.
According to Pollard, the evolution of new technology, such as LED grow lighting and the Internet of Things (IoT), has complemented the development of indoor soilless cultivation systems.
“IoT can be used to automate and regulate indoor farming by monitoring water levels, nutrient levels, pH levels, and temperature and light requirements of plants. “A farmer can be in control of the harvest at all times, wherever he or she is physically present.
“One of the biggest benefits of indoor farming is that produce can be farmed at any time of the year. Thus, a farmer can sell produce at out of season prices, and supermarkets can stock fresh local produce all year around,” says Pollard.
No-soil farming
Pollard started investigating various methods of indoor soilless cultivation in 2016 and fine-tuned them in 2019 to create a healthy, productive indoor farming system.
An entrepreneur by nature, he took note of the various challenges in traditional South African agriculture, including water scarcity and security risks. He also noticed the demand for certain leafy greens and microgreens in cities.
Thereafter, he traveled to the US, Europe and Asia to research systems that could be applied in the South African agricultural environment.
He went on to establish UCI at the N4 Gateway Industrial Park in Pretoria East.
“What makes UCI’s technology different from most other indoor systems is that a farmer can start small and expand by adding additional racks to the system. So there’s no need to commit to a huge capital investment to get started,” Pollard explains.
The UCI model enables the farmer to control the light hours, nutrients and moisture. It is automated to produce rapid harvest cycles with predictable results, and can be used in a small space. Crucially, it is also affordable.
A key advantage is that the plants can be grown without the use of insecticides and herbicides, as the crops are grown in a controlled environment.
Pollard predicts that farms of the future will be urban-based, and crop cultivation will have to become far more sensitive to water and energy usage. There are many cost-effective options for indoor, soilless cultivation, and these allow farmers to move from the fields to the city.
Indoor production is also an easier entry into farming; it can be started by any entrepreneur, or even a retiree, he adds.
A wide range
The options offered by UCI range from small household units to large-scale commercial systems. Regardless of size, they can deliver crop yields of up to 10kg/m2.
The household units are small, with just enough space to service the average household and to plant a variety of crops, such as leafy greens, microgreens and berries.
The household system was also developed for educational purposes and can be used as an entry into indoor soilless cultivation before a large capital investment is made in a commercial unit. UCI has developed a curriculum that explains the A to Z of indoor hydroponic farming.
The company’s industrial units include climate control and a lift system, which makes harvesting easier.
Depending on the type of crop, the return on investment is between two-and-a-half and five years, while high-value crops such as microgreens have a payback period of less than a year on capital investment.
Growing with ease
Plants can be grown from seed to harvest in 28 days, three times faster than that achieved with traditional farming.
“The plants are grown in a controlled environment under 12 to 16 hours of LED lights, giving you optimal harvest and zero wastage,” explains Pollard. In addition, produce grown in UCI’s systems has proved to be of excellent quality and offer good taste.
The entry commercial turnkey solution system contains a 10m-long and 1,9m-wide row, and the buyer can choose to fit between three and 12 levels.
For example, a 10m-row, five-level-high farm enables 100m2 to be planted in a floor space of only 20m2. “The higher you go, the more your yield per square metre,” says Pollard. The grow trays and spacing between plants are designed for optimal growing and yield. No sunlight is needed for this method; all the systems use LED grow lighting.
“LED technology provides the best energy efficiency, which saves you money in the long term,” says Pollard.
Production
A 10m-long unit can handle 54 plants per tray. At 12 trays per level and at five levels, this equates to 3 240 plants per unit.
The lighting is usually kept on for between 12 and 16 hours a day, depending on the requirements of the plants.
“The more light they get, the faster they grow,” says Pollard.
The system can handle a variety of crops such as lettuce, spinach, baby spinach, marog (imfino), cherry tomatoes, strawberries, basil, watercress, sage, zucchini, beans, fodder and a range of microgreens and herbs.
To illustrate potential crop yields, Pollard and his team have used the five-level demonstration system at UCI’s premises to grow 250g lettuce heads in 28 days under optimal growing conditions. A yield of more than 18kg per tray has been achieved.
“Compared with traditional farming, the only major cost drivers are electricity and wages,” he says.
Each tray contains about 20ℓ of constantly recirculated water, and total water use is approximately 1 250ℓ/month. The system is extremely water-friendly, as almost all the water is absorbed by the plant.
“No water is wasted, hence the saving of 90% compared with traditional farming,” says Pollard.
He adds that climate and temperature control is a key factor in the grow room, and even the water temperature is cooled or heated as the plants require.
“We can mimic the controlled growing environment of certain crops as they require. “The system works with any water, and tests are routinely conducted to see what nutrients the plants need, and all variables can be adjusted according to the needs of the plants.
“We have a nursery system that grows the plants from seed to seedlings. After about seven days, the seedlings can be transported into the commercial system; the fully grown plant is then ready to be harvested after another 21 days,” Pollard says.
Due to the way in which the system operates, the chances of a pest infestation are very low.
“Biosecurity is crucial and we prevent any pathogens and pests from entering the facility.”
Harvesting a system that is 10m long and has five levels requires about three hours with two people.
With rapid urbanization increasing the demand for food, UCI’s system offers a number of key advantages.
It brings the farm closer to the people, thereby improving food security, and it reduces transport costs, in turn lowering the carbon footprint of supplying food. The system also offers good potential as a job creator.
“Our aim is to get entrepreneurial farmers to start utilizing the empty spaces in cities, such as empty buildings in city centres. Such spaces can be used to grow food, provide jobs and supply retailers directly,” says Pollard.

Today, Vertical Field announces its Star-K certification so that any company or community in cities around the world can benefit from growing and supplying its own fresh kosher greens locally and easily. Star-K recognizes that Vertical Field's pesticide-free, soil-based urban farming operations lend themselves to producing naturally kosher products, in its highest level.
In fact, the greens are grown indoors in Vertical's Field's Urban farm, entirely free from exposure to insects, and since green agricultural produce is a naturally occurring plant that comes from the earth, they're almost fail-safe kosher after washing.
Vertical Field offers a never-been-done-before approach for supermarkets, restaurants, institutions, and hotels to take complete ownership of the supply chain by growing their own vertical living walls of delicious, naturally kosher greens — at the same time removing transportation expenses, reducing inventory costs, and ensuring year-round food supply regardless of climate or weather conditions.
CEO of Vertical Field Guy Elitzur said, "What Vertical Field offers together with the global kosher organization Star-K is the opportunity for anyone to enjoy kosher produce grown onsite at the local supermarket, restaurant, university, or company. You cannot get fresher greens if you pick it right off the wall once it's ready for harvesting. With Star-K's support and collaboration, Vertical Field is changing the way people think about kosher greens and vegetables."
President of Star-K Dr. Avrom Pollak said, "Vertical Field's revolutionary agro-technology offers the kosher consuming community a healthy, organic, pesticide-free solution for agricultural produce, ensuring peace of mind and promising quality. We are thrilled to be a part of this innovative new food supply initiative that makes kosher-eating communities' lives easy and healthy."
Vertical Field is committed to scaling the urban farm concept as well as exploring collaborations in agro-tech.

How To Grow Microgreens With Children
Microgreens can be taught to everyone, not just adults. Let’s face it, most children stay inside and play video games. What do children know about farming, besides crops and cows?
Microgreens can be taught to everyone, not just adults. Let’s face it, most children stay inside and play video games. What do children know about farming, besides crops and cows? This is the current stigma that has been associated with farming for the longest time. That’s great and all, but along came microgreens. Watching the microgreens sprout is really something that can’t be explained. It’s exciting and might inspire children to be urban farmers or just entrepreneurs. Introducing microgreens to children at a young age is engaging and fulfilling. It’s become a field where innovation is key and the younger generation has plenty of ideas. It’s also a fun and exciting way to connect kids with nature.
Here at Nick Greens Grow Team we worked with Kipp One Academy Charter school and had put in place a program that developed an understanding of where food comes. It was a success as the children and faculty all had to work together to make this work. This made it possible for children to connect with and appreciate the food they eat. They might even want to eat veggies if they see them in the form of microgreens. Having the microgreens program also gave children the fundamentals. The fundamentals are important because children can attempt to grow much more challenging microgreens.
Here are our steps to grow at home with your children:
Grab a 10X20 tray with drainage holes and fill it 1" thick with moist coco coir.
Weigh 14 grams of arugula microgreens Seeds into seed shaker, then broadcast evenly across the 10X20 tray.
Apply an even mist of water to the tray, then cover it with a humidity dome and place it in a dark space.
Germinate for two or three days in a dark location with at least 75% - 80% humidity. Water as described in step three at least once a day.
Remove humidity dome from the tray on day two/three. Then begin feeding plants your favorite fertilizer using a low flood/continuous flow method of irrigation.
Micro Arugula will be ready for harvest around 7-14 days, They will need about 8 to 16 hours of light with a typical fluorescent grow light about 12"-15" from the base of the plant.
It’s a fun process and gets children to get active and appreciate the world. Who knows maybe your child will start a whole urban farm in your backyard or basement.

Michigan State University’s Specialty Crop Research Initiative Grant Funded by The USDA
The initiative, OptimIA, which stands for Optimizing Indoor Agriculture, aims to improve the profitability and sustainability of indoor leafy-greens production
The initiative, OptimIA, which stands for Optimizing Indoor Agriculture, aims to improve the profitability and sustainability of indoor leafy-greens production.
February 11, 2020
A multi-university team of horticulturists, engineers and agricultural economists led by Michigan State University (MSU) has received a four-year, $2.7 million grant from the U.S. Department of Agriculture (USDA) to study indoor production of leafy greens. Industry partners have matched funding, bringing the project total to $5.4 million. The investigators on the grant include Erik Runkle, Roberto Lopez and Simone Valle de Souza of Michigan State University; Chieri Kubota of Ohio State University; Cary Mitchell of Purdue University and Murat Kacira of University of Arizona.
Leafy greens include commonly consumed vegetables such as lettuce, kale, and microgreens. Production challenges outdoors have led to interest in growing these specialty crops hydroponically in controlled environments, such as indoor farms. However, there is little information on whether this is economically viable. Capital and operating costs can be significant for startups, especially as it relates to light-emitting diodes (LEDs) and cooling systems. Leafy greens are a good candidate for indoor farming because they can be grown rapidly and in relatively small spaces. Indoor environments are heavily controlled, so growers aren’t constrained to a small geographic area within the U.S. There are, however, other geographic concerns.
The team and its collaborators have three major goals:
Defining optimal profitability based on yield and other high-value attributes of the plants, such as nutrition content.
Optimizing indoor environmental conditions, such as humidity, air movement, temperature, light and carbon dioxide concentration, to increase yield and high-value attributes.
Encouraging indoor farming stakeholders to collaborate with academic and industry groups that are working in controlled-environment agriculture.
The long-term project goals are to help integrate indoor farming into the specialty-crop segment of agriculture in the U.S.; to increase the sustainability and hence profitability of this rapidly emerging sector; and to locally produce leafy greens that have higher quality attributes.
To this end, economists will better understand operating and capital expenditures (capex), and define risk and production scenarios that are most profitable. Horticulturists and engineers will improve production efficiency, product quality and value-added attributes of leafy greens for reliable, consistent, year-round production. In addition, the team will design and test more effective localized air-distribution methods suitable for indoor production systems, as well as develop strategies to better manage humidity around plants to reduce tip burn.
While the project focuses on leafy greens, the results will also inform a wide range of controlled-environment growers through the development of growth recipes, strategies for nutritional content and anthocyanin enhancement, environmental management recommendations, and insights for economic sustainability as well as market and consumer perception of locally produced crops.

U.K Aeroponic Start-Up LettUs Grow: 'Not Everyone Is Sold on Vertical Farming Initially'
Thankfully, the image of vertical farming is changing rapidly. Nowadays, aeroponic technology "is recognized more as a business plan rather than a pipe dream," said Langley. Indoor farming has also been getting loads more attention
December 05, 2019
Farmers across the globe are searching for sustainable, tech-savvy alternatives as climate change increasingly impacts agriculture's profitability.
LettUs Grow, a Bristol-based aeroponics tech company that provides technology to farms in the U.K., thinks it may have a solution.
The vertical farming tech provider gave us a glimpse into the future of aeroponics and an overview of its innovation.
Overcoming challenges in vertical farming
"There's a perception about vertical farms - not everyone is sold on it initially," LettUs Grow's India Langley told FreshFruitPortal.com.
The company's greatest challenge has been public perception. Oftentimes people imagine that their produce comes from local, small scale farms. However, the reality is that most farms are industrial entities - at least in the U.K. - explained Langley.
Thankfully, the image of vertical farming is changing rapidly. Nowadays, aeroponic technology "is recognized more as a business plan rather than a pipe dream," said Langley. Indoor farming has also been getting loads more attention.
So, the task aeroponics tech companies face is "educating people that the food is just as nutritious".
As vertical farming becomes more mainstream, companies like LettUs Grow have seen more demand for their products.
What, then, does the technology do and what will the future of vertical farming look like?
LettUs Grow walked us through its technology's evolution and the benefits it provides to today's agriculture industry.
The idea for LettUs Grow arose when three Masters students at the University of Bristol - Ben Crowther, Jack Farmer and Charlie Guy - developed a table-top aeroponics system. This in-home model worked so well that the group decided to scale it up.
"We started out solely making hardware, so the physical grow beds," Langley said. The company then began crafting software it calls Ostara - which reduces energy costs up to 15%.
Founders saw that traditional aeroponics - which use high pressure - were inefficient. Old methods, which involved firing liquid through a nozzle to create aerosols, lead to clogging and system failures. In order to reduce waste, LettUs Grow sought alternatives.
To do this, it got rid of nozzles entirely. It also developed a new way of making aerosols. These innovations allowed the platform to be scaled up.
"What the three founders thought was that if they were seeing this increase in growth rate in these home-kits and their main goal was to reduce waste, they would do much better taking this technology and applying it to farm-scale applications."
The result was an aeroponics system that reduces food miles, increases food freshness and "helps farmers keep farming".
According to Langley, there is big problem in the U.K. with farmers needing to diversify. Climate change has posed a risk to farmers' income and vertical farming provides a solution, she said.
She specified that "one of the things that indoor growing does is that it protects the crop" and ensures that farmers profit regardless of weather conditions.
Benefits of aeroponics and LettUs Grow's advice
When asked about the benefits of aeroponics versus other indoor farming methods, Langley said "aeroponics has been an improvement" on hydroponics. This is because it gives the plants better access to "free gas exchange".
In short, it provides the "ideal environment" to grow, claimed Langley. Aeroponics "holds plant roots out of water" and sprays plants with an aerosol. Plants in aeroponics grow 70% faster than in hydroponics, she stated.
She went on to explain the strategic benefits and challenges faced by farmers.
"The main thing that holds you back is whether or not there's a business case for it," said Langley.
"We always advise people who are working with us to think really carefully about what they grow."
LettUs Grow suggests farmers plant crops like microgreens, quick growing crops, and tender crops that struggle to be transported. While the company has tested "dozens" of different plants at its two farms, it encourages farmers to plant profitable crops like basil.
Looking forward, the future of the company
LettUs Grow continues growing as demand for its technology increases. While farms all around the world have requested the company's products, it says plans for expansion into Europe - and eventually, worldwide - are in the works for upcoming years.
Currently, it only provides technology to farms in the U.K.
It seems a lot of demand from countries that face resource issues. Places that contact LettUs Grow tend to be dry regions like the Middle East or regions with less sunlight. Additionally, it is gaining popularity in "places where there's not as much land" in more developed countries like the U.S.
Other urban farming schemes like startup Bowery, Gotham Green and Fifth Season have been gaining steam in U.S. cities.
To meet the needs of diverse farms that request its technology, Lettusgrow plans to continue expanding its product line.
In the past, its implementation of Ostara farm management software allowed it to offer a platform that collects data on plants, oversees irrigation and traces crop history.
Most recently, it has partnered with Octopus Energy to create "vertical power software". The new technology platform reduces energy costs for farmers, making operations more efficient.
It does this by changing the price of energy throughout the day and minimizing costs during peak hours. This both saves customers money and incentives farmers to have more sustainable operations, detailed Langley.

New Zealand: Vertical Farming Takes Off In Former Wellington Nightclub

Shoots Microgreens is one of NZ's first vertical farms, housed in a former nightclub.
Once nightclub goers used to bounce off the walls of a Wellington basement, but now it's been transformed into an urban market garden supplying over 80 restaurants.
The lights are still there, but the moody blues have been replaced by state-of-the-art multi coloured LED grow lights.
Shoots Microgreens is a start-up company growing tiny crops mainly for restaurants, but with some of the produce sold through stores such as Moore Wilson.
Microgreens are the intense flavoured first shoots and leaves, and are popular among chefs and bartenders for garnishing meals and cocktails. Many familiar leaves can be used as microgreens, including mustard, basil, rocket and coriander.
Co-owner Matt Keltie started the business last year and it now employs three fulltime workers, although it is yet to make a profit.
While ostensibly a hydroponic-style system, Shoots Microgreens is marketing itself as different to such common garden businesses that have been around for decades.
ROSA WOODS/STUFF
Shoots Microgreens co-owner Matt Keltie has started a business in a former Wellington nightclub.
First, the location: vertical farms have sprung up in a number of major urban centres where the crops are grown close to where people consume them – in high rises, derelict buildings and abandoned warehouses – reducing carbon emissions and maximising unused spaces in cities.
"It's all about using an efficient production area, recycling water, and having a lower carbon footprint."
Secondly, the crops are grown without the need to cart in soil and spray the chemicals that conventional growers use to control animal pests, fungal diseases and weeds.
Thirdly, everything is recycled including the water and growing trays, and deliveries are made using e-bikes.
Keltie started the business in a garage before moving into a smaller space than where he is now. Once he had successfully realised the proof of concept and started to supply restaurants, he had enough confidence to launch the business.
The Energy Efficiency and Conservation Authority (Eeca) helped with a $12,300 investment in the special LED grow lights under its "Gen Less" campaign.

Compared with traditional incandescent hydroponic lamps, the LEDs are cool to the touch, and can be frequency controlled to improve productivity – they grow the shoots around twice as fast as their halogen counterparts.
The LEDs conserve 45 percent more lighting electricity, saving Keltie's business about $25,000 a year on its power bill.
With customisable spectrums of light, the colour of LEDs can be adjusted to optimise the growth of each specific variety of microgreens. As they do not produce heat, they can be stacked at every vertical layer, with no risk of heat damaging plants, as with incandescent hydroponic lamps.
Every day chefs order their microgreens and are delivered or collected.
The non-soil medium the plants are grown in is a trade secret, although Keltie is planning on moving to a hemp-based medium once it becomes available.
Keltie says the taste of the microgreens is governed by the light applied to the plants – the lights are one component but managing and changing alone or all components of the growing system influences the plants.
"When I take two trays of the same plants grown under different numbers of bulbs, some chefs can tell me how they've been grown because there's a subtle difference in flavour. It's all about the mix of water and lights.
"Not only do the LEDs provide the right growing spectrums, they are hellishly efficient in terms of power."
A supplier provides the fertiliser in the right sorts of ratios but Keltie is starting to test which plants take up which nutrients, so he can apply a specific rather than a broad spectrum mix. For example, peas do not require much nitrogen.
ROSA WOODS/STUFF | . Microgreens are used as garnishes or in cocktails.
He admits there has been a lot of trial and error in the start-up period.
"When people say how far down the track are you with your learning, I say about 5 per cent, I've still got a solid 95 percent left to learn. But we hope to start soon in Auckland, once we've ironed out the issues here."
Prices start at $7.25 for a tray of peas, which grow in a little over a week, whereas slower growing red sorrel is priced accordingly higher.
Quotes from famous historical figures are mashed up in a call to arms for climate change campaign Gen Less, encouraging New Zealanders to get more out of life by using less.
Capitol Restaurant owner-chef Tom Hutchison says he buys the microgreens every day.
"It's good that they're doing well, the product is fantastic."
Hutchison is not so much a fan of the very young greens, preferring the more mature, larger leaves.
Eeca technology innovation manager Dinesh Chand worked with Keltie to help get the project off the ground.
"This project not only shows potential for LEDs to reduce electricity use and increase productivity, but is a great example of reducing transport-related emissions. In this case, supplying locally eliminates the equivalent annual carbon emissions of taking 20 cars off the road."

In London. microgreens are grown in old air raid shelters beneath some of the capital's busiest streets.
Vertical farming can save up to six times the ground space that conventional farming uses. Keltie said it was not a replacement for traditional New Zealand farming yet, but was part of its future.
Eeca chief executive Andrew Caseley said the authority's intention in running the Gen Less campaign was to mobilise New Zealanders to be world leaders in clean and clever energy use.
Companies that have already joined Gen Less, include Westpac, Countdown, New Zealand Post, Stuff, Wishbone Design, Ecostore, Lewis Road, and Ethique.
"Less" refers to reducing greenhouse gas emissions from energy use. People could join the campaign by walking their children to school, switching to a more efficient car such as an EV, buying sustainable goods and services, and using LED bulbs, he said.
