Currently I am growing 1 plant (see sig) under 345 watts of CFLs. Thats 15 23watt CFLs. Temps are an issue, ranging around 90-100. Although I know this is high, I havent seen any PROBLEMS derive from it. Heres my question. Will 1 300 watt HPS give off the same heat or more without proper ventilation like cool tubes. My temps are fine when the A/c is on, but i dont leave it on when we go out for the day. I would rather use HPS, but curious about temp levels. Space is about 3' deep x 4' wide x 5' tall
