Could i grow with one of these? I could put the bulb at the top of my closet and then just put the plant on the shelf, its one of those florescent bulbs. Or could i buy some bulb for this somewhere for pretty cheap? it was originally for my blacklight but it broke. im not looking to get the greatest buds, or the best results, i just want to watch the plant grow and get a feel for it and get a reward (; Thanks guys!!
