Most retailers receive produce by truck, but Whole Foods Market can now receive it by elevator.

The greenhouse that sits on the top of Whole Foods’ Brooklyn, N.Y., store recently started harvesting from its crop of lettuces, leafy greens, herbs and seven types of tomatoes.

This is the second rooftop hydroponic farm run by Brooklyn-based Gotham Greens, and the grower’s first to be built on top of a retailer. Gotham Greens leases the space from Whole Foods.

Gotham Greens’ greenhouse is located on top of a Whole Foods Market in Brooklyn.“The industry leader in urban farming, Gotham Greens has been a valued local supplier of high quality, flavorful and fresh produce to Whole Foods Market since 2011, making this greenhouse partnership a natural and extremely exciting next step in our relationship,” said J’aime Mitchell, green mission specialist for Whole Foods’ Northeast Region, in a media statement.

Although the Austin, Texas-based retailer had already been sourcing products from Gotham Greens’ other Brooklyn farm, the proximity of the new farm brings a new meaning to local, with the grower delivering to Whole Foods three or four times a week.

“This greenhouse is 20,000 square feet, which is about a half of an acre, but our yields are equivalent to a nine-acre farm. So it’s actually very, very productive,” Viraj Puri, co-founder of Gotham Greens, told SN.

Thanks to the climate-controlled facility, kept from 65 to 75 degrees, Whole Foods will be able to receive product year-round. Gotham Greens expects to grow 150 tons of produce annually at the new farm, and will also supply some restaurants.
