ordered the nute monitor, it was like $140 shipped. shop around for "24-7 nutrient monitor" they are made by Control Wizard. read some reviews on this board, and everyone seems to have had a good experience with them.
and thanks for the tip about the spacing....i thought that may be an issue. this first grow im going to keep kind of small, and just in that one side of the closet. just to get my feet wet. after that i am going to build out the other, larger side of the closet for a flowering room. maybe use a bigger bin so i have have more space between the plants. and get a 400w HPS in there. if im feeling really ambitious i may try to build and ebb and flow unit in there.
can anyone explain the benefits and weaknesses of the various common hydro systems (DWC, SWC, Ebb and Flow, Drip, etc)? only reason i have considered doing a E&F system in the future is because i have seen quite a few flowering rooms do this.
i was also thinking of attaching some mylar to the top of the...well top. to bounce light back up. is this a good idea? im thinking it would give the lower branches some extra light.
also for sprouting, i was going to use three 100w CFL's, but can i just use the 250w MH and jsut give em some distance? which method would be preferable?
