Ok hopefully every one understands the principles behind aquaponics. Fish poop then life happens. Most pepole know AP. as peagravle beds with plants planted directly in the gravel or floating raft desings with the plants on the rafts. Although these desings are good for some plants ie. lettuce they seem to fall short for heavy feeders like cannabis. In part due to the lack of phospurus produced by the fish. So long story short I have spent the last year fine tuning a AP. method that overcomes the few pit falls to cultivating heavy feeders in AP. I will start with what sets my method apart from all others I have seen: I use plastic pots with pure coco (NO FERTILIZER) in the bottoms of the pots then add a rich organic only mix to top off the pots. Chems will kill the fish. EvEn to much water solubale organic fertalizer will kill them ie. blood meal. The coco at the bottom keeps ferts from leaching out too bad and it wicks water up the pot. I also highly recommend more coco and perlite or whatever your preferance is to add more drainage and air pockets you dont want them to drowned. Basically I use soil as my primary source of food for the plants. The fish just add that little extra in a water soluable form plus they keep the water alive and healthy. Its like having a auto water system feed by a healthy pond wich is hard to do if you live in a condo.
