today i went ahead and bought a 250w HPS light to go along with my 2 42-watt cfl's. do u think the knew light will be beneficial for my plajnts? im considering getting two more when my 4 plants enter flowering in a month or so

wud sseveral 150 watt HPS lights work just as well as one bigger one? seems like a light on each side of the plant would have as possitive an effect as one big on over the plant
