Currently running 9 autos under a 600w dual spec (running 660w lumen boost via omega ballast) , the area the 9 covers around 4x4 to 5x5ft , it's run in a cool tube , would I benefit more from running two 400w in cool tubes as apposed to the one 660? I would like to of used 660 and a 400 but the temps become to much!
