I wish I had the link handy, but I don't. My youngest brother got me excited about something nearly a month ago. He popped up a video on his iPhone that showed a fish and veggie farm in a simple hoop style greenhouse that took next to nothing to run. And it was in Wisconsin where the winters are just as bad as those here in Michigan.
The idea was pretty simple. You build a simple hoop greenhouse, construct a plastic lined fish tank down the middle, throw in 1 tilapia (perch also work) fish for every 1 cubic foot of water, build a bench over that that housed salad greens and duck weed, and above that you hung baskets with tomatoes in it. You pump water from the fish task into the tomato plants, that water runs off into the salad greens and duck weed, you trim the salad greens for sale to people, trim the duck weed to feed the fish, and you harvest the tomatoes whenever ripe. The fish poop gives the plants nutrients and the plants clean up the water for the fish.
And then you heat the whole structure with piles of composting manure in the four corners.
I'm tossing around the idea of doing this in my own yard. Thoughts?
