Inside a cavernous warehouse in South San Francisco, 16-foot-tall walls of kale and other greens stretch down aisles twice the length of a bowling lane. Matt Barnard, CEO and cofounder of Plenty, the startup that designed and built the indoor farm, points to two types of mustard greens called mizuna and tatsoi. “This is one of the blends that we are working to position against junk food,” he says.

Barnard wants to change how the world eats by changing how food is grown. The new farm, which will begin selling produce to San Franciscans later this year, is the latest iteration of its indoor growing system, designed to grow food as efficiently as possible in any space, so cities anywhere can have access to locally grown vegetables—optimized for flavor—at any time of year. When I first visited the company’s headquarters in 2017, it used only a small amount of the space, a former electronics distribution center in an industrial neighborhood. A few months later, Softbank led a $200 million investment round in the startup. The new version of Plenty’s farm now sprawls over a much larger part of its headquarters, and the company plans to eventually replicate it near large cities globally.

Each step in the process is now automated. In one corner of the massive warehouse, a bright yellow robot picks up a tower filled with kale that was growing, minutes earlier, in one of the aisles of greens next door. Gently turning the tower on its side, the robot sets it on a conveyor belt where a spinning wheel neatly trims the greens to harvest them. When the farm opens, this will be one of the last steps before produce is delivered to grocery stores or directly to consumers (the company already sells greens from its earlier, smaller farm through a local food delivery service called Good Eggs, along with some independent groceries). In another corner, robots pack trays with soil and seeds and deliver them to another room to germinate. Along another wall, four robots inside glass boxes carefully lift seedlings out of trays and plant them into the tall white growing towers. Back in the growing room, infrared cameras and sensors monitor the indoor climate, and software adjusts details like the precise “recipe” for light or water to create the best flavor in the plants.

“We essentially coax a different flavor profile out of the plants by giving them the right recipe,” says Barnard. Each day, the company runs harvested crops through its “sensory” department, evaluating factors like size and flavor and tweaking the growing environment as needed for the next crop. “We take those plants and analyze what’s in them, and then we work to give subsequent crops exactly the right recipe so that these things are lovable. And that’s critical. That’s how we get to 10-year-olds asking their mothers for our kale.”

Right now, only around 1 in 10 Americans eat as many fruits and vegetables each day as federal guidelines recommend. If it’s possible to buy local, freshly harvested produce in Minneapolis in February—rather than wilted greens that spent a week on a truck from Arizona or California—Plenty believes that people will be more likely to want to eat them. Because the company can control the growing environment, it says that it can achieve flavors that aren’t consistently possible in fields. It can also sell varieties of produce that are too delicate to survive current supply chains. Consumers don’t really want to buy iceberg lettuce, Barnard says. But it’s a huge crop because it can survive both difficult growing conditions on farms and then travel thousands of miles. With a local journey, Plenty can sell crops that don’t exist in typical supermarkets now. I tasted wasabi arugula, a spicy wild green that mimics the heat of the Japanese condiment.

The company wouldn’t comment on the cost of its system. But it says that it’s still possible to sell greens at the same cost as those grown on a traditional farm. One of the largest costs for indoor farms is energy use, especially from lighting; in the last year, Plenty cut energy consumption by 80% per kilogram of plants grown, and it expects to cut that further. Roughly a third of the value of vegetables sold in the eastern U.S., it says, comes from transportation from farms in places like California or Mexico. Indoor farms can also avoid the cost of days in distribution centers and other parts of those long supply chains. There’s also intrinsic value for consumers in the fact that greens grown in food safety-certified facilities can avoid the contamination that sometimes happens outdoors. In 2018, in three outbreaks, romaine lettuce grown on traditional farms caused 300 infections and hospitalized 128 people; six died. Water contamination from nearby livestock was the culprit. Plenty uses purified tap water inside a space so pristine that it doesn’t have to treat its greens for them to be safe to eat (“prewashed” greens from farms are often washed in bleach in an attempt to kill germs).

Indoor farming still hasn’t proven itself at scale. Aerofarms, another startup with a massive indoor farm at its headquarters in Newark, New Jersey, said in 2015 that it expected to build 25 farms over the next five years; to date, it has built one large farm in addition to its headquarters. FarmedHere, which said in 2015 that it planned to build 18 farms near major cities. Two years later, the company shut down. Bowery, a New York-based, Alphabet-backed startup that also uses robotics, has two farms so far, though it raised a $90 million round of investment in late 2018 and plans to expand. Plenty itself had planned to open a farm near Seattle by this point, but decided to focus on building its tech platform. Still, it can move quickly: The company completed the design for its new automated Bay Area farm last November, began construction in December, and was operational by March.

To begin with, like other companies in this space, Plenty is growing greens, because they are particularly economical to grow in this way. But at another location in Wyoming, where it tests new varieties of crops—700 over the last year—it is also perfecting the “recipes” to grow foods like strawberries and tomatoes. Indoor growing is unlikely to ever replace growing in fields, both because some crops are better suited for outdoor growing and because of the scale required. But as available space for farmland shrinks and the global population grows, indoor farming could help fill some of the gap. Plenty declined to share the exact size of its new farm or expected annual production, but depending on the crop, the company’s indoor growing system can produce between 150 and 350 times as much produce as the same crop in a field. It could also become more necessary in some areas as outdoor farms struggle with drought, heat waves, flooding, and other impacts from climate change. Indoor farms use a small fraction of the water required in places like California.

Barnard believes that the company can grow quickly. “I think people are going to be stunned at the speed with which a lot of what’s available in the fruit and vegetable aisle is from a Plenty farm or from an indoor farm,” he says.

Robot Farming Startup Iron Ox Sells First Produce In California

Robot farming startup Iron Ox has announced that it’s selling robot-reared leafy greens in a single location in California. The firm, which launched last October, is offering three varieties of greens at the San Carlos branch of Bianchini’s Market, a family-owned grocery store that specializes in local and organic produce.

Iron Ox is one of a number of companies trying to automate the human-intensive work of agriculture. It uses a combination of robotic picking arms, hydroponic vats, and self-driving porters to grow vegetables. But despite its repeated claims that its farming is “autonomous,” humans are still needed for a lot of the work. Laborers plant seedlings and package plants when they’re ready to eat: robots just tend them while they’re growing.

One benefit is that robot farms can be located nearer to customers because of their smaller physical footprint. Iron Ox says the greens it’s producing for Bianchini’s travel just 0.6 miles to get there, which is half the distance traveled by a typical head of lettuce. This means lower transportation costs and fewer food miles, a big factor when it comes to the environmental impact of what you put on your plate.

But the scale of Iron Ox’s operation is limited. It’s selling just three varieties of leafy greens and delivering them to Bianchini’s just once a week. The prices aren’t exorbitant, but they are on the expensive side. A two-ounce box of red-veined sorrel will go for $2.49, a two-ounce box of Genevieve basil will cost $2.99, and four heads of baby lettuce will be $4.99.

Vertical Farming Robot Wins Design Challenge

The winners of the 2018 Valtra Design Challenge were announced at the EIMA Show in Bologna, Italy. The competition which started in April and ended on September 23rd was targeted globally to designers, academic design students, design studios and automotive suppliers. This year’s challenge was to design the multi-purpose vehicle of the future: a machine that can handle multiple tasks to meet future needs and that is more efficient than today’s highly specialized machines. 

The first place of the competition was awarded to the work “VERTICAL” by Austrian design team Benjamin Miller, Jack Morris, and Alireza Saeedi. The jury praised the concept as being a very creative interpretation of the challenge theme. “At first glance it looks very specialized, but if you judge the complete system instead of only the tractor, a versatile and holistic concept for the future emerges. The concept takes care of everything from seeding to distribution of food”, comments member of the jury Hans Philip Zachau.

“Valtra has been widely recognized for ground-breaking and visionary industrial design. We started the Design Challenge in order to raise awareness of future challenges in the agricultural community and society at large. It is also a platform for designers to showcase their innovations.” comments head of the jury and industrial design & user experience manager at Valtra, Kimmo Wihinen. “The Valtra Design Challenge is the world´s largest design contest in agricultural machinery and one of the biggest in the off-road vehicle industry. The high number of innovative and high-class entries shows us that there is a demand for this type of competition, and we are already working on the theme for the next edition”, he adds.

The Valtra Design Challenge 2018 Jury members were Kimmo Wihinen from Valtra, Brandon Montgomery and Sam Freesmeyer from AGCO, Hans Philip Zachau from Lighthouse Industrial Design and Paolo Grazioli Frozen Design Tokyo.

The Valtra Design Challenge was organised for the second time in 2018. This year the competition has received 107 entries from 32 different countries and six continents. The first prize of the Valtra Design Challenge is a €10,000 cheque.
