Aquaponics is a highly sustainable method of producing food. It combines hydroponics (growing plants in water) and aquaculture (the farming of aquatic animals, usually fish) in a nearly closed loop system. Fish waste converts to fertilizer for your plants. The plants are grown without soil in a greenhouse, so you won't be battling common garden pests, and at the end of the day you get to harvest fresh vegetables as well as delicious fish.
This method is optimal for gardeners and farmers of any size and scope, and allows for far more food per square foot to be produced than with traditional methods. Whether you're simply feeding a small family or producing for the market, there are aquaponic designs that fit your needs. Conceivably, a single individual working alone could grow tens of thousands of dollars worth of produce using this efficient method.
