Or you could spiral wrap the airstone with a tube with holes in it and make a fitting so you could disconect the tube and stone for easy maintence or replacement. Just put tons of holes in it so the air stone is always wet but there is no nute mix in it to give the roots unlimited growth. May need bigger pipes so optimal growth but your set up would work to. Same design just larger return pipes, man this thread rocks. I feel like a kid at a carnival. I will check in a bit so I dont keep spiting out tons of short posts making the thread five pages long by the time you get to read it again.

One love
