Fulton, Indiana – Caston High School Students Build Aquaponics Lab

Aquaponics combines aquaculture — the raising of fish — and hydroponics — cultivating plants in water. As the fish inside a water tank are fed, their waste creates nutrient-rich water that gets pumped through a filter and into the plant beds, supplying the crops with food. The plants, in turn, clean the water that gets sent back to the fish tank.
