So I can get 2 150watt hps and ballasts free. Right now I run 320 watts of cfl..... I'm assuming hps will be better right? Now what about temps... For 2 hps compared to 300 watts of cfl... I have my cfls right above the plants,about 1 inch. Temps are around 87... How hot do hps really get? I would be able to keep the hps about 2.5 -30 feet above the plants
