I have a spare room about 11 foot by 11 foot (roughly) and about 9 feet high. Currently have two 4.5 x 4.5 x 6 grow tents set up side by side taking up pretty much half the room. In one tent I have two Quantum Badboy T5 8 bulb units (total of 16 bulbs and about 4x4 feet and this is strictly for flowering). In the other tent I have a 900 Watt Blackstar LED for flowering. Just picked up a 250 Watt HPS in trade and was thinking of adding it next to the LED. My question is, would it be smarter/more efficient to just get rid of the tents and hang all four lights from the ceiling? Would that give me more control over temps and stuff?? What are your opinions?
