Huge Rooftop Farm Is Set for Brooklyn

from nytimes.com: Brooklyn is fast becoming the borough of farms. On Thursday, Bright Farms, a private company that develops greenhouses, announced plans to create a sprawling greenhouse on a roof in Sunset Park that is expected to yield a million pounds of produce a year — without using any dirt. The hydroponic greenhouse, at a former Navy warehouse that the city’s Economic Development Corporation acquired last year, will occupy up to 100,000 square feet of rooftop space. Construction is scheduled to start in the fall, with the first harvest expected next spring. When finished, the greenhouse will rank as the largest rooftop farm in the United States — and possibly the world, Bright Farms officials say. This spring, Brooklyn Grange, another rooftop farm developer, is set to open a 45,000-square-foot commercial operation at the Brooklyn Navy Yard.
