CEA Grower Spread Says Its Vertical Farming Tech Is Ready for ‘Mass Production’ of Strawberries

Kyoto, Japan-based controlled environment agriculture (CEA) company Spread said this week it has developed technology that will let it mass-produce strawberries in a vertical farm setting.

Spread is “old guard” when it comes to indoor farming, having completed its first large-scale vertical farm in 2007. Since 2018, the company has also operated its Techno Farm, which uses robotics to automate much of the grow process for plants. Up to now, Spread has grown leafy greens inside these environments. And like a few others in the vertical farming space, the company is now applying its technology and learnings from that process to growing strawberries. 

Strawberries still top the Environmental Working Group’s “Dirty Dozen” list, which means they contain the highest levels pesticides of any fruit. They are also extremely perishable and prone to damage during the shipping distribution process. That makes farms like the ones Spread operates suitable grow environments, since vertical farms are inherently pest-free already and typically situated closer to consumers. Spread’s Techno Farm, for example, is located in Kansai Science City, which sits at the intersection of the Kyoto, Osaka, and Nara prefectures in western Japan.

Strawberries are in high-demand in Japan as in other parts of the world, and Spread joins companies like Plenty, Oishii, and AppHarvest have already said they are planning to grow the fruit in a CEA environment. Oishii also grows the über-premium Omakase berry — normally only available in a specific region of Japan for a short time — inside its facility. 

Spread said this week it is considering distribution of its strawberries to Europe and North America as well as Asia. The company is also working on grains, mushrooms, and other fruits as potential future crops on its farms. 

Q1 2021: AppHarvest Bets on Robots, Strawberries and More Data in the Greenhouse

Control ag company AppHarvest is adding more of both crop types and technologies to its budding greenhouse network, according to the company’s Q1 2021 earnings call this week. That includes strawberries, leafy greens, harvesting bots, and lots of data.

The company, which went public in February, is best known at this point for the 60-acre greenhouse facility it operates in Morehead, Kentucky, where it grows beefsteak tomatoes. AppHarvest sent out its first shipment of these tomatoes to grocery stores earlier this year. Customers now include Kroger and Wendy’s.

CEO Jonathan Webb said on the company’s earnings call this week that two more Kentucky greenhouses, one in Richmond and one in Berea, will be operational next year, and that with them, AppHarvest will start growing leafy greens and strawberries. Webb pointed out that while his company may have started with tomatoes — a fairly traditional crop when it comes to greenhouse growing — the eventual aim is to “grow the company into a trusted high-tech sustainable food company.”

As far as that tech goes, AppHarvest’s CTO Josh Lessing said on the investor call that the company is investing in “robotics, artificial intelligence, teleoperation, and proprietary seed genetics.” To date, its biggest move has been the acquisition of Root AI, a startup best known for its crop-harvesting bot Virgo. (Lessing was the cofounder and CEO of Root AI before the acquisition.)

“Presently, we are training our intelligent robot Virgo to manage crops and inform growing decisions,” Lessing said on the call, adding that Virgo could eventually be configured to harvest multiple different crops, including delicate ones like strawberries — hence the company’s announcement to move into the realm of berry growing. 

As a crop, strawberries are highly suited to the controlled-environment agriculture (CEA) realm because they are extremely delicate, perishable, and normally require boatloads of pesticides when grown outside. Moving the grow process indoors, to a fully controlled environment, means better protection for crops from weather hazards, no pests and therefore no need for pesticides, and more consistent temperatures and humidity levels that can ensure better-tasting plants with a more robust nutritional profile. 

Given the amount of sunlight strawberries need for optimal growing, greenhouse settings are obvious candidates, since they rely largely on the sun with only supplemental LEDs. However, vertical farms, which use LEDs to mimic the sun’s light spectrum, are also now growing strawberries. Plenty, Oishii, and SinGrow are just a few of the names on that list. Whether one method will wind up superior to the other will (among other things) depend on what the end product tastes like as well as how much it costs to grow, sell, and buy.

For AppHarvest, though, the real win with technology will be not so much about the crops it can grow but the data Virgo and other tools can collect. That data can in turn get analyzed and turned into actions and insights applicable across the AppHarvest greenhouse network. “Granular plant level data from each fruit means we can learn exactly how to optimize quality, production, sales and logistics,” said Lessing. “This foundation will give us the opportunity to restructure the world’s food supply in order to mirror the hyper efficient e-commerce landscape.”

Along those lines, the company will expand beyond these first three facilities in the future. Two more projects will be announced this summer and are slated to be operational in late 2022. Webb said on this week’s call the company is on track to operate 12 greenhouses by 2025. By then, one imagines those facilities will grow a whole lot more than greens, strawberries, and tomatoes.

Advanced Farm Technologies Raises $7.5M Series A for its Strawberry Picking Robot

Advanced Farm Technologies (AFT), an agtech robotics startup, has raised a $7.5 million Series A round of funding led by Yamaha Motor Ventures & Laboratory Silicon Valley (“YMVSV”), the strategic business development and investment arm of Yamaha Motor Co., Ltd., with participation from Kubota Corporation, Catapult Ventures, and Impact Venture Capital. This brings the total amount raised by AFT to $9.2 million.

Based in Davis, CA, AFT creates robots as a service for farmers. It has developed the T-6 robotic strawberry harvester which operates on farms in the Oxnard, Santa Maria, and Salinas-Watsonville areas of California.

Agriculture is a hot area for robotics companies and automation. In addition to the fact that farms are facing a human labor shortage, farm work is hard work. It entains repetitive, manual labor often in hot conditions. Automating some of those tasks would help save people from getting heat stroke or dehydration after being out in the fields all day. Robots can also pave the way towards more efficient farming with precision application of water and pesticides.

Despite their potential benefits, robots haven’t had the best track record when it comes to picking strawberries. Even with the aid of computer vision, ripe berries can be hard to spot. They’re also fragile, so plucking them has to be done with the right amount of robotic care.

Perhaps this is why so many companies are tackling the problem. In addition to AFT, CROO Robotics, Traptic, and Agrobot are all working on robotic strawberry harvesters.

For its part, AFT says it will use the new funds to further expand its robotic strawberry harvesting program and “innovate in other areas.” If the company can nail robotic strawberry picking, that will indeed be pretty sweet.
