Ok, here is a picture of my Light and AC unit. Once I hit flowering my room will be under 80f, and I will have my 400watt hps light above and (6) 43 watt cfls, and a t-5 48" light on the side. Full mylar walls.
My next grow will have a room set up for vegging also, In that grow I will use a 400watt MH light and the cfls also. You have to remember, it is 110f outside right now, and hits 120 easy in the middle of summer. So heat is a bitch, even with cfls.

Sorry if I got defensive, But when I started this I figured it would be maybe $100, I am pushing $1,000 right now. I think my set up is pretty nice for the second grow. You guys do not see my other set up, my room, my fans, my semi automatic res change out system i built or anything. WHICH I AM SO HAPPY I BUILT. Now my plant tray does not sit on my Res. I can change my Res in my flower room in nothing flat. 5 minutes of time to change, 5 minutes of time to clean. That includes emptying my Res also. Next I am going to set it up where I have R/O water running to my grow rooms. Carrying, and buying that water is the worst part of changing my Res. Even though it is at most stores out front in a machine for .25 cents a gallon. It is not the money, it is the work. Fill the Jugs, put them in you truck, drive home, carry the SOB's up stairs, then try and pour them into tank with out spilling them.

This new set up is so easy. throw a valve, throw a switch, wait a minute, shut off switch, add nuts, check ppm, check PH. throw another valve, walla Res. is changed
