Aquaponics in its most basic form is a system whereby the waste products from the fish are recycled to feed the aquatic plants. No water is wasted in this process as it is then cycled from the fish tank to the grow beds and then back to the fish tank, where the cycle begins all over. These plants then feed the fish in a cyclical motion.
Phil. I think sustainable farming isn't really about the financial feasibility, but rather the method. Everything we do will be part of the system and play a roll. Growing this way can be, and usually is, more expensive to get going, especially if you grow indoors. But generally, it's more about the overall finish because you are creating a better quality fish.
