How Hydroponic School Gardens Can Cultivate Food Justice, Year-Round

These greens are among the hydroponic crops grown by students at Brownsville Collaborative Middle School, in Brooklyn, N.Y. In June, the students started to sell discounted boxes of the fresh produce to community members.

After a full day of school a few weeks ago, 12-year-old Rose Quigley donned gloves and quickly picked bunches of fresh lettuce, Swiss chard, kale, mint and oregano. But she didn’t have to leave her school in Brooklyn, N.Y., or even go outdoors to do it.

Quigley is one of dozens of students at Brownsville Collaborative Middle School who in the past year built a high-tech, high-yield farm inside a third-floor classroom. They decided what to grow, then planted seeds and harvested dozens of pounds of produce weekly.

The vegetables never stop coming because the crops are grown hydroponically — indoors, on floor-to-ceiling shelves that hold seedlings and plants sprouting from fiber plugs stuck in trays, each fed by nutrient-enriched water and lit by LED lamps. The students provide weekly produce for their cafeteria’s salad bar and other dishes.
