Element Farms Plans a New High-Tech Greenhouse Customized for Growing Spinach

Element Farms announced this week its plans to expand its greenhouse operations and build a new, 2.5-acre facility designed specifically to grow baby spinach. This will be the company’s second high-tech farm, the first being a 1.5-acre facility that already grows arugula, lettuces, beet greens, and, of course, spinach. Like the first, the second farm will also be located in Lafayette, New Jersey, according to a press release sent to The Spoon.

Baby spinach is a popular produce type in the U.S. But in many parts of the country, it can only grow outside at certain times (spring and fall), and its delicacy and susceptibility to bacteria and disease make it a prime candidate for local, indoor farms. 

However, growing spinach indoors is actually quite challenging, which is one of the reasons we don’t see more controlled environment agriculture (CEA) companies doing it. In particular, spinach is susceptible to the water-borne pathgen Pythium aphanadermatum, a water mold that attacks the plant roots and causes poor crop quality and crop death.

When we spoke a while back, Element’s CEO Serdar Mizrakci explained that technology allows the company to add another layer of precision control to better aid against water-borne pathogens and other diseases. To that end, Element uses its own proprietary technology to monitor plants, calculate recipes for plant nutrients supplemental lighting, and help spot problems during the grow process. As in other CEA settings, greens are grown without pesticides and meant to serve customers no farther than about a day’s drive away.

The company doesn’t have a lot of competition right now when it comes to spinach, BrightFarms being one notable exception. As technology improves and costs come down for CEA growers, more companies may join the efforts to grow spinach indoors.

Element says its existing farm, located in Lafayette, New Jersey, currently delivers directly to more than 120 retailers, including Key Food, Whole Foods, and e-commerce shops Misfits Market and FreshDirect. When the new farm is up and running, Element will be on track to ship 2 million pounds of greens per year. 

The new farm is slated to open later in 2021. Additional farms are planned for other U.S. markets and will be announced “in the coming year.”

Gotham Greens Heads West, Partners With University of California-Davis to Grow Better Greens

NYC-based Gotham Greens today announced its plans to expand its controlled ag operations to the West Coast with a 10-acre greenhouse in Solano County, California. The forthcoming facility will be located near the University of California-Davis, with whom Gotham will collaborate on future greenhouse research and innovation. 

Gotham, which currently operates greenhouses in New York, Illinois, Colorado, Rhode Island, and Maryland, raised $87 million at the end of 2020, part of which the company said would go towards expansion.

The California greenhouse is expected to open in 2021 and, like other Gotham facilities, will grow leafy greens that will then be sold to retailers and foodservice businesses. Having a facility on the West Coast will increase the number of potential customer for Gotham, which supplies its greens to local markets rather than shipping them across the country. Not including the California facility, Gotham’s farms serve about 40 states. Within those, the company has partnerships with Albertsons, Whole Foods, Target, and other major grocery retailers, as well as e-commerce deals with AmazonFresh, FreshDirect, and Peapod.

Gotham also uses a good deal of tech to control the various growing environments of its greenhouses (light, temperature, humidity), and to automate certain repetitive tasks. The partnership with UC Davis is partially meant to advance research and development in this area. “The new greenhouse facility enables opportunities for Gotham Greens and the University of California system to collaborate on research and innovation focused on advancing the science, workforce, technology and profitability of indoor agriculture globally,” Gotham said in a statement.

The company’s expansion comes at a time when tech-powered greenhouses are increasing in both size and numbers. Earlier this year, AppHarvest went public and Little Leaf Farms raised $90 million to expand its number of greenhouse. Revol Greens did the same in September of 2020 with a $68 million fundraise. Not all of these greenhouse operations share territory yet, but at the rate of these expansions, they may well do so in the near future.

Gotham Greens has raised a total of $130 million to date.

Revol Greens Launches Its Own Plant-Based Nutrient Source for Greenhouses

Greenhouse lettuce grower Revol Greens today unveiled a proprietary plant-based nutrient source with which it can feed the plants in its indoor farms. Dubbed Plant Fed, the product is currently patent pending, and its existence on Revol’s farms means leafy greens will be fed entirely by plants and not with animal ingredients, as is often the case with fertilizer.

Revol raised a $68 million funding round in September 2020 to build out its network of greenhouses. Currently, the company operates a 10-acre greenhouse in its hometown of Owatonna, Minnesota. Two more facilities, one in California and one in Texas, are slated to open in 2021.

The Revol process relies on as much automation as possible, though not necessarily of the robotics variety. Machines automatically sow the seeds in grow trays, which are then moved from the germination room to the greenhouse via a water flume and placed in a massive pools of water with their roots exposed. Human hands pick up the trays to move them from sowing machine to flume then out of the water pools, but people never touch the actual plants.

Meanwhile, much of the farm’s water source comes from UV-sterilized rainwater and snowmelt collected from the roof of the facility. This is an improvement over traditional farming, where produce often shares a water source with nearby animals, thus upping the risk of contamination to the plants. 

Like other hydroponic-based operations, Revol’s method grows plants without any soil. Instead, the new Plant Fed nutrient source will be pumped into the water that is circulated into the pools in which plant roots are exposed.

“The plant-based natural fertilizer developed by our research and development team is an extension of our goal to provide the healthiest, most natural leafy greens to our customers,” Revol’s CEO Mark Schulze said in today’s press release. 

Revol is certainly not alone in that goal, with recent activity in the high-tech greenhouse space underscoring the sector’s possibilities when it comes to future farming. Gotham Greens raised $87 million for its own greenhouse network at the end of 2020, and of course there was the news of AppHarvest going public earlier this year. 

Revol’s Plant Fed nutrient is only feeding the greens in the company’s own facility for now. Whether the company ever decides to sell its product to other controlled ag operations remains to be seen.

AppHarvest Expected to Go Public Next Week via SPAC

AppHarvest’s expectation to go public is fast becoming a reality. The controlled agriculture company announced today that it is expected to complete its merger with Novus Capital Corp., a special purpose acquisition company, which will enable it to start publicly trading on the Nasdaq on Feb. 1.

Special purpose acquisition companies (SPACs), also called blank-check companies, often provide a faster IPO process for companies. AppHarvest first announced the deal with Novus just a few months ago, in Sept. 2020.

Since then, the four-year-old Morehead, Kentucky-based company has reached a few major milestones, including harvesting the first crop ever from its 60-acre indoor farm and starting construction on two additional farms in the Appalachian region. 

The company’s massive greenhouse facility runs off a mix of sensors, LED lighting, and hydroponics to grow produce 365 days per year. Because of the farm’s Eastern Kentucky location, abundant rainwater can be used to power the hydroponic system, minimizing resources used.

AppHarvest’s location also means it is within a day’s driving distance of about 70 percent of the U.S. population. This potentially vast reach combined with the growth possibilities an IPO can provide will help AppHarvest further realize its ambitions to make high-quality, pesticide-free produce available at a manageable price point to all Americans, not just the affluent ones.

The company sent its first shipment of beefsteak tomatoes to U.S. grocery stores last week. Meanwhile, AppHarvest said in a recent statement that it plans to construct more facilities across Kentucky and Central Appalachia, with the intent to be running 12 farms by 2025. The forthcoming IPO will undoubtedly aid in this process.

Abandoned Spaces and Automation: What to Expect for Indoor Farming in 2021

Controlled-environment agriculture — also simply known as indoor farming — had a big year both in terms of activity and investment dollars. While once we might have questioned the sector’s economic viability and ability to actually feed a growing global population, a lot of those doubts have diminished and indoor ag in its many forms now has an important role in our future food system.

What that role is, however, will continue to evolve over time. Here are a few thoughts on how that will happen over the next 12 months. 

More automation.

Automation isn’t new to controlled-environment agriculture, but its presence as a part of indoor farming operations has increased over the last several months and will continue to in the next year.

In the context of controlled-environment farming, automation can refer to any kind of technology that removes manual human labor from the growing process. In some cases that includes robots that plant and harvest greens or move trays of produce around the farm. More often, though, automation refers to software that can calculate the optimal environmental temperature for each plant, know when plants need to be fed and harvested, and handle many other calculations that would otherwise require a person to have horticultural and technological (hardware and software) expertise.

Moving into 2021, we’ll definitely see a few more robots buzzing around the indoor farm. But the bulk of automation will be about software. 

More grocery store partnerships. 

Many large-scale indoor farms started out selling their leafy green wares to restaurants and hotels. The pandemic, of course, put a hold on that in 2020, and controlled-environment agriculture operations had to look elsewhere for customers. 

Enter the grocery store. From container farms at local markets to Kalera’s partnership with Publix stores across the U.S., more indoor farming companies are growing their greens either onsite at grocery stores or within throwing distance of them. 

This could in turn help bring the cost of greens grown on high-tech farms down, since the shipping and distribution steps will be less resource intensive in many cases and nonexistent in others. 

More underutilized space.

One of my favorite stories from 2020 was this one, about a company called Wilder Fields that turned an abandoned Target store in south Chicago into a massive indoor farm.

Many companies are constructing their own facilities from the ground up, while others stick to smaller scale container farms that are a bit more mobile. Finding existing space, such as an abandoned big box retailer, seems a logical middle ground, and one we’ll likely see more of as companies work to lower costs and keep their environmental footprint down.

Predictions pieces, of course, are always a bit of a crapshoot, and even if the above forecasts turn out to be true, they’ll be but a smattering of the activity that will happen for controlled-environment ag in 2021.

Revol Greens Raises $68M to Build Out High-Tech Greenhouses in the U.S.

Revol Greens announced today it has closed a $68 million funding round for its network of high-tech greenhouses the company says will eventually supply 33 million pounds of greens annually to the U.S. The round was led by Equilibrium Capital. According to a press release sent to The Spoon, this brings Revol’s total funding to $215 million.

The Minnesota-based company says it will use the new investment to launch its third facility, which is a 20-acre farm in Texas that could expand to 80 acres in the future. 

Revol is part of a new wave of companies marrying greenhouse growing with technology systems that allow food producers to grow crops year-round, in totally controlled environments. Its system uses closed-loop hydroponics and, when necessary, supplements natural sunlight with LEDs. It also collects data on plant growth to ensure crops have the correct levels of water and nutrients they need to grow.

As they’re based in Minnesota, the folks behind Revol are no strangers to the kind of extreme weather that makes growing crops outdoors impossible for parts of the year. But extreme weather is also a consequence of climate change, whether it’s fire, drought, or insect outbreaks, and it is becoming more widespread. In traditional agriculture, that could mean an increase in pests, flooding or heavy downpours that threaten crop yields, and increases in carbon dioxide that decrease the quality of products. 

Revol is not alone in merging the greenhouse with high tech to provide an alternative to traditional agriculture. AppHarvest is currently building out a massive greenhouse facility in Appalachia. The company recently raised $28 million. Iron Ox, which raised $20 million earlier this month, is bringing robotics to the greenhouse, and a company called Lufa has taken the greenhouse concept to rooftops in cities.

Getting greens closer to cities is also one of Revol’s goals. “High-tech greenhouses give us the ability to return to regional food systems with farms that produce our food near our communities,” David Chen, CEO of Equilibrium, said in today’s press release. “Regionalism gives us resiliency, food security, and addresses the threat of climate change to our food system. Greenhouses are the tech disruptor in a 10,000year-old agriculture sector.”

Revol CEO Mark Schulze added that by the end of 2021, the company will be “the world’s largest indoor lettuce producer.” 

The company’s first greenhouse launched in 2018 in its hometown of Owatonna, Minn., followed by a second facility in Tehachapi, Calif., which Revol is in the midst of building out.
