Fish!

They’re very small right now, but they look happy. 100 Tilapia fingerlings each about an inch and a half long are darting about producing waste which is being converted to nitrites by friendly bacteria and fed to our various greens. In addition to the fish, we now have an aeroponic system joining our hydroponic and soil based growing beds. 18 tiny sprinklers are spritzing the roots of arugula, chives, lettuce and chard. Excess water falls back into the 275 gallon fish tank below, being oxygenated in the process.
