hmmm ok well thanks for your input.. currently im just running a drip soiless setup kind of thing so I guess ill stick with this i just run water thru like once every two days, but im going to try to figure out a way to deal with temperature to lower it and maybe ill try some later. Soil is just kind of a bitch cause getting all that soil inside blows.

Im sure I could replicate it for 100$, but I was actually just wondering how the water goes back to the reservoir... like a pump or what?
