Re-ducted to heat better now. How important do you think keeping off ground is. One room i keep off ground, other new flowering room I haven't done anything to raise them yet but they seem to be doing alright. Heating pads would add to my power bill so not my best option-I run my furnace fan, intake, exhaust fans 24/7 already which normally works but my basement is drafty and cold in the low temps.
Have two rooms that work together-200W cfl for veg/400Whps flower, and 2-600W hps for flower in separate room. 400 runs in day, 600s at night.
