your both in luck. There is a very odd fellow...very smart...very odd I think...but he is very much into aquaponics which is fish/plant growing. You can take it a step further and not use artificial fertilizers for the plants. That requires some serious knowledge though to be able to create not one, but two stable environments that are self sustaining. It can be done, insert fish food on one end, out pops MJ on the other end. Fairly slick if you ask me.
