Aquaponics: Fish Poop to Plant Roots

Aquaponics is a mashup of hydroponics and aquaculture. It is the practice of using fish wastewater as fertilizer for plants, whose roots filter the water, cleaning it sufficiently to be returned to the fish. In this episode, we visit homeowners, a non-profit, and even a restaurateur using this highly efficient system to grow a stunning array of fruits, vegetables, and freshwater fish.
