Hydroponic spinach culture. Organic spinach growing hydroponically at a hospital farm. Hydroponics is the cultivation of plants without soil. Instead, the roots of the plant are immersed in a trough through which nutrient-rich water trickles. The organic produce from the farm is used in meals for patients prepared in the hospital's kitchen. Photographed at Henry Ford West Bloomfield Hospital, Michigan, USA.
