Looking at the recent discussions below, I saw aquaponics. For now, I tower garden, outside in summer and 2nd year of inside during cold months.
I actually started learning about aquaponics in regards to a symbiotic fish and garden set up long before doing the tower thing. I still have dreams of setting up something, though I am not sure where the best place would be, though out basement has crossed my mind.
I have a cousin in another state who does the fish and garden thing, who explained his filtering system. We need to take a field trip to see this! Hmmm we homeschool, so I can make this count, right?
I should see if his wife is on Bakyard Chickens...
