Barrel-ponics is simply aquaponics in a barrel. It was invented by Travis Hughie, founder of www.fastonline.org. It is a recirculating system using the elements of aquaponics which is built out of economical materials that can be found almost anywhere in the world. The entire system can be run on just 40 watts of power which makes this an ideal system for use in poor and rural countries.
“If you are looking for an introduction to aquaponics that is simple to build, fun to watch and demonstrate to friends and family the joy of soil less gardening, then this small unit may be for you. It is capable of growing various vegetables and herbs and would be a wonderful addition to the home kitchen as a source of fresh herbs and occasionally (depending on the species used) a fish or two. What it most likely won’t do is provide the vegetables to sustain someone on it’s own. That is for a much larger system. Fish production is also limited because of the small size of the unit. The actual production possible is mainly dependant on the operators ability to manage it.”
