Veg plus Fish equals FOOD

These are some photo's of the Aqua Ponics system at AVI where this relatively small system produces head's of various lettuce's and strawberries through out the year. It is the very small version of what is being built at "FOO"(farm on ogden) by one of the other Core teams. The main, and really only significant difference between the two is that the Aqua system uses fish and their waste's to feed the plants vs the Hydro that use's only pure water. I have not gotten, or had the time to really get into the main specific points, but the idea is that the fish are typically raised in indoor tanks, troughs or outdoor ponds, where they produce excrement. The water with the waste from the tank flows to a hydroponics tray where plants grow in the water without soil. The waste is toxic to the fish but is a rich fertilizer for the plants. As the plants absorb the nutrients, the water is purified for the fish. The clean water can then be recycled to the fish tank.
