Aquaponics is the combination of aquaculture and hydroponics. Aquaculture is fish farming. Hydroponics involves growing plants in nutrient-rich water. The fish excrete ammonia that would become toxic to the fish in a regular fish bowl, but in the Water Garden, the ammonia-rich waste is pumped up to the grow bed of the plants above and is absorbed by the plants. The ammonia-rich wast helps the plant grow twice as fast as in traditional farming! The clean water is then filtered back to the tank, creating a low-maintenance, self-cleaning cycle to foster a healthy fish and herb garden.
