Create your own ecosystem with this indoor herb garden that doubles as a fish tank. The Water Garden uses a closed-loop Aquaponics system. This ancient farming method uses the waste of the fish to grow plants and clean the water. Essentially, fish waste produces Ammonia which can be toxic if it accumulates. However, the beneficial bacteria in the Water Garden converts ammonia into nitrates. Plants need nitrates in order to grow, cleansing the water of Ammonia. This fantastic, simple cycle is allows you to grow healthy herbs and plants. The Water Garden combines a 3-gallon fish tank with a vegetable and herb growing bed. The closed-loop system can then fit easily on any kitchen counter, classroom or office desk. The waste from the fish provides nutrients for the plants, and the plants clean the water for the fish! Grow a variety of tasty herbs. The Water Garden comes with organic wheatgrass and snow peas seeds to get you started. However, you can expand your garden to include parsley, coriander, mint, rocket, mixed greens, and other varieties of basil.
