Next summer I might start a big project but first I wondering if you can use a bell siphon in hydroponics to empty your grow chamber . I know you can in Aquaponics . My next question has anyone ever try to grow pot in an Aquaponics system. Grow fish to grow pot and then sell the fish and smoke the pot . I kind of think this would be really cool. Just imagine you can be growing your pot just by feeding your fish. I been looking at some of these systems and it seems you don't need much fish. I also seen them use earth worms in there medium to eat some of the fish poop and give some micro nutes to there plants. I seen them grow tomatoes which are pretty close to pot. What does every one else think about this . I think it would be what you call pure organics.
