Hello Mad German! Thank you for your response. Yes I would like to call you when I get closer to that time. Were still building the green house right now. It will be a 20' X 30' That should be finished in the next 45 days or so if finances hold up. We hope to use a Hybrid mix starting with a media gravel grow bed that would flow into 24' long DWC floating raft ponds. The Media beds would be the solids filter so to speak with the bell siphon. I suppose this would be on a timer as you said. We want to be a small time commercial farm to sell Lettuce and other veggies to the local farmers market and a host of other restaurants. We have a 2.38 acer farm that has well water here. Electricity is the greatest problem because we already have several Koi ponds and fountains on our property. Were sort of maxed out on our power capabilities unless we were to install a larger panel inside our house. I prefer not to do this as my power bill already exceeds $275 to $300 a month.

    

      I would love to build a "Off the Grid" system or close to it if possible. I really like all of the "green" technology and being a fully sustainable grow system that would set an example that I could maybe show Schools and other county and state officials. If you show the owners of the local restaurants this type set up, they would be more willing to buy your produce over some mega farm in Mexico or central America. ;)) Greg McCord
