Dude that is frickin awesome. Both the wife and I are looking into this.
Awesome, I started reading up on aquaponic systems about 2 months ago. I've been gardening in raised outside beds for about 10 years, 8 beds of various sizes in an approximately 20'x50' plot beside our house. I happened upon an article on aquaponics and thought "holy crap... that's great!" We (wife and I) had been talking about digging a small pond in the back yard (we've got a couple acres) to stock with fish, but now that we're onto the idea of aquaponic farming we're scrapping the pond idea and gonna quit the outside garden (or reduce the size of) in favor of a greenhouse, probably 16'x24', that we can grow in year round and set up several aquaponic systems.
Not hippy at all, just smart IMHO. Nothing better than getting as self sufficient as you can, and growing your own food, fishies and chickens included, is unbeatable.
