speedhorse - Your right about them drinking more water than nutes. I'm not sure what you mean by RH? Instead of using less nutes i got another tip about highering my Ph a bit. I've been keeping the Ph at 5.5 -5.7. The local hydro shop suggested i try it to see if they will take more nutes at a little bit of a higher Ph. Don't know why i didn't think of that .

Gen - Thanks. They are 150w spirals. They are warm bulbs i got at HD along with the sockets for them. Two bulbs, two sockets, one ext cord = $28. Not bad huh for DIY.

turtle - yes, i think. But if you start with 1000 ppm in 2gal and end up with 2000 ppm after 1gal was taken away, then does the plant not take up any nutes? I think i am more confused then when i started :stoned: <me.

LOC - Now that the res is farther from the light and better covered from the cannapy, my res temp is at 69.

My prayers were answered today in the form of a check. Co2 is no longer going to be an issue for me. Finally :sadcrying. I will setup the system and run the lines tonight. But i am not sure how long i should let it run for. For anyone who knows the formula: my growspace is 6 cubic feet, the flow meter preset at 30psi and i also got a 24hr timer with 15min slices. Thanks again. Anyone?
