I am a professional Aquaponist. That is I set up aquaponic systems for people. This is using aquatic animals like fish, that produce waste, which is broken down by bacterias into uptakable n-p-k. This is all organic, and my brand new prototype needs no water removal, no flushing, no cleaning, and it is totally self-sustaining. All one does is feed the fish and top off every 3 weeks. I even have automated fish feeders. I'm a medical marijuana patient, and I've decided to use my system to grow cannabis. I found a cutting-edge way of injecting organic bloom ferts into the lavarock pots without killing the fish, but still maximizing p-k. Micronutes abound because it is a topped off with hardwater; perfectly loaded with micronutes. I got frogs, Goldfish, Cichlids, Koi, snails, self-sustaining duck weed that supplements feed, worms, ladybugs, dragonflies, and a few Mollies. My nitrates run at about 1200 ppm, all organic, and I have the ability to inject direct nutes into the root system using my own technique. I also have a leaching/flushing technique through a seperate system. This is all organic, self sustaining, and I grow tomatoes, parsley, basil, lettuce, squash, various bog plants, strawberries, and a few others. This system feeds me, and provides me with very potent medicine. My last harvest of Og Kush (will post pics), and Grandaddy Purple (Will post pics), smoked better than any of the top grades at the local dispensaries here in California. It was high yield, organic, smooth smoke, massive trichomes, and rapid growth. I'd be happy to answer any questions reguarding my 3 years of research in the field of aquaponics.
