Gotham Greens is a 15,000-square-foot hydroponic farm on the roof of a Brooklyn warehouse. It had its first harvest in June, and expects to produce 100 tons of food per year. The crops (mostly lettuce) grow in rows of white plastic tubing, their roots massaged by recycled water, under grow-lights and fans controlled by a central computer system. The system collects data from sensors throughout the room and adjusts the environment accordingly. This pampered produce will eventually end up on restaurant menus and shelves at stores like Whole Foods.
Two years ago, Forbes predicted that by the year 2018, 20 percent of the food consumed in U.S. cities will be grown in places like this. It’s safe to say that’s almost certainly not going to happen. Right now, urban-grown produce represents a minuscule slice of the food system. But there are several plausible scenarios that could make such food more commonplace in the city kitchen of the future.
