  1. -- UPDATE -- Solar-Powered Aquaponic-Hydroponic PARTS - FOR SALE Disassembly In Progress - I'm currently DISMANTLING my Custom-Designed, Ken-Built, Solar-Powered Aquaponics & Hydroponics Fish-And-Food System and SELLING THE INDIVIDUAL COMPONENTS. It was designed to be modular and has already been taken apart and moved once ((from the back patio to the new greenhouse)) and everything except the 4'x4'x4' 400-gallon fish tank can be removed from the greenhouse and transported anywhere you want to take it for re-assembly and operation. NOTICE: This system will occupy a 16'x10'x10' space (greenhouse) and can run 24 hours/day off sunlight supplying you with more fish (Tilapia) and vegetables than two people can eat. And, yes, it's perfect for growing cannabis REALLY FAST too. Initial asking price is $500 for everything.. If seriously interested, call me 817-944-7373 or email or send me a Private Message on FB. As I take it apart I am saving some of the major components and bundling them up for easy transport and re-assembly. - If you enjoy DIY projects, this might be just what you need.

  2. Thanks, Ande... Found some useful info on those links. I'll proceed with my initial design (constant-level, continuous-flow). KW
  3. Constant Water Level Pros & Cons ? I'm building a new system using a 500-gallon IBC for the fish tank and 2 65-gallon barrels cut in half for the grow beds. In my design the water level across both the fish tank and the grow beds is 3' above ground. The water flow is as follows... A solar-powered pump moves water from the sump into the fish tank. The outflow pipe lies in the bottom of the fish tank, runs up the side to the 3'-level then horizontally out to each of the 4 half-barrel grow beds. As the water level in the grow beds reaches the 3' level it flows out and down 2" PVC pipe into the sump (a 3rd 65-gallon, upright barrel). The pump is positioned 1' above the bottom of the sump barrel and pumps water from the sump back into the fish tank. A solar-powered air pump forces air thru a plastic tube down to the bottom of the fish tank to help add oxygen to the water. So, there is no siphon and the water level remains constant across the entire system. The plants' roots will be submersed in the water 100% of the time, but, the air pump will be used to oxygenate the water for both the fish and the plants, so, will this system provide enough oxygen for the plants? I could re-design the system to use a bell siphon in each grow bed but I'm wondering if I can run a constant-level system as described above instead and that system provide sufficient oxygen for the plants? My limited research did not find any good articles on fill-and-drain systems vs constant-flow/level systems. Thanks, Ken Winters*
