i do believe that aquaponics is certainly a very good answer to world hunger. my brother, a friend and i are trying to put together a system that would provide a lot of the nutrition for a family of four. it is based on solar with a package of $200. the supplimental organic nutrients, some of the equipment will be donated by a friend that has a corporation he is a large provider of nutrients for soil and soiless farming, this includes hydroponics, bioponics, and eventually aquaponics when the additional nutritional needs are known to put together a formula specifically directed to aquaponics that will benefit the aquatic animals as well as the horticultural side. these systems and nutrients will hopefully be given to needy families that would be capable of maintaining such a system. his products are completely organic, full of good little critters.
my goal is to put together a system where neither the aquatic animals or the plantlife is compromised by a lack of proper nutrients, or enviorment. i am never satisfied with "that's good enough".
