have you considered PL-L lights for that grow space like these
http://www.ebay.com/itm/2-T5-FLUORE...968576?hash=item1c22be1bc0:g:yOcAAOSwWKtUvX3l I use this type of light in a 2ft by 2 ft vegging closet and have used them for flowering for 2 years before setting up a larger flowering closet using a standard 4 bulb T5HO fixture and they were giving me 0.7 GPW in flowering. the bulbs lasted 1 1/2 years of continuous use and were cheap to replace
