It’s so interesting to see all the different ways people are taking to farming. We’ve already covered a number of angles. Now Adele Peters at FastCoexist writes about how would-be farmers in Brooklyn are testing out “vertical farming.”
“When it opens this fall in Brooklyn, a new urban farm will grow a new crop: farmers. The Square Roots campus, co-founded by entrepreneurs Kimbal Musk and Tobias Peggs, will train new vertical farmers in a year-long accelerator program. …
“The campus will use technology from Freight Farms, a company that repurposes used shipping containers for indoor farming, and ZipGrow, which produces indoor towers for plants. Inside a space smaller than some studio apartments—320 square feet—each module can yield the same amount of food as two acres of outdoor farmland in a year. Like other indoor farming technology, it also saves water and gives city-dwellers immediate access to local food. …
“It’s intended for early-stage entrepreneurs. ‘We’re here to help them become future leaders in food,’ says Musk, who also runs a network of school gardens and a chain of restaurants that aim to source as much local food as possible.
“After building out the Brooklyn campus, they plan to expand to other cities, likely starting with cities where Musk also runs his other projects—Memphis, Chicago, Denver, Los Angeles, Indianapolis, and Pittsburgh.”

My dad was involved with an early hydroponic lettuce farm in CT. The only part I miss about hydroponic farming (which is what your photo appears to be?) is the dirt — and all the amazing microbes who live in healthy soil (whose value we are finally beginning to recognize and respect).
Hooray for microbes and songwriters like you, Will, who write odes to healthy bacteria!
