Brooder lamps with CFLs
I was curious if someone could tell me what distance a 150watt (equivalent to incandescent) CFL bulb in a brooder lamp should be from the plants?
I'm currently spotlighting an African lily we're overwintering in our basement. It seems to be reacting well to it (it wasn't getting enough window light down there and was pretty poor looking) and greening up, but it's on the ceiling maybe 3-4 feet above. Is this adequate or should it be closer?
