Well since its a floro u can keep it as close as 4 inches. IMO. Thats what i do anyway for veg. then for flower i hook up my hps but that has to be kept min 14" away due to heat and intensity of the bulb.

is its a CFL ( compact floro light ) or a bar floro? if its a CFL , you want it 3 inches away from the very top of the plant and a circulation fan blowing air around your grow area.

Depends on if its a CFL or a tube Fluro. CFL IMO need to be 4-6 inches off the plants as they do put off more heat than an tube fluro. tube fluros you can keep 1-3 inches off the plant tops because they release their heat from by the ends of the light (near the pins) CFLs heat throughout its whole structure.
