Bring the garden inside with the Back to the Roots Water Garden. This mini aquaponic tank is a closed-loop ecosystem — the betta fish waste fertilizes the plants on top, and the plants filter and clean the water for your fish — not your average betta fish bowl! Aquaponics is the combination of aquaculture, or fish farming, and hydroponics, or growing plants in nutrient-rich water. The fish excrete ammonia that would become toxic to the fish in a regular fish bowl. In the Water Garden, the ammonia-rich waste is pumped up to the grow bed and absorbed by the plants, helping them 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.
