hang onto those cfls i have a 400w mh hps n my plants r like 3 ft to 4 1/2 ft high so since i dont have a level canopy the few cfls i have work great for lower level n side lighting...plus when the girls r n bed at night i use the cfls in another room for my little sprouting seedlings that cant handle the 400 w light yet...but very nice grow +rep for sharing!
