I'm looking at getting my feet wet with aquaponics, have started gathering water tanks,(12' dia x 54", open top), looking at several options for grow beds, already have greenhouse frames,( 1-30' x 96', 1- 44' x 144'), and abundance of spring water. I want to learn the art of aquaponics before diving into commerical production. I was in live production agriculture, and understand mechanical/ electrical sytems and want to incorporate this into my operation. I plan to be heavier in vegetable production, than fish. I was headed in the direction of hydroponic tomato production but discovered aquaponics. Please point me in a direction for gaining knowledge and direction. I'm pretty handy with my hands and very resourcefull. Any and all comments will be appreciated and considered. Thank you in advance, btw, I've been silently watching and listening and feel you guys have a real insight into the future of agriculture.
