I got a 8'X4'x7' tent, 3x3 ebb & flow table w/40g res and pump, a TON of rockwool and hydroton (like enough for 25 grows!!), 24 slotted plastic planters, 400w ballast, reflector, hanger set, and MH & HID bulbs, a germination station, 2 liters of each nutrient I need (grow, micro & bloom), 1 liter of worm castings, a bottle of PH down, a TDS meter, 2 analog timers, a squirrel cage exhaust fan w/flanges and a carbon filter for $1400 bucks. I think you may have spent a bit much, but I don't know.
I will say this about the lights...I moved my babies (3 of them) from fluoros to MH a few days ago. My fluoros were 3" above teh tops of the plants. I set the MH at 9" above the tops (where I could not feel any heat on my hand) and two hours later my plants showed heat stress. I moved the light to 19" above the tops, and this problem reversed itself. So....move your lights up is my advice...I am a nube, but am learning alot here and in many books and other forums. peace!
