try to find the 2700k cfls for flowering. those are the best for bloom. i use a combination in my stealth cab. i have 2 45 watt 2100k cfls, 2 45 watt 6700k cfls, a 65watt 6700k aquarium strip and a 125watt vitalume 2700k cfl. i usually pull about a qp total at harvest from 1 or 2 plants. i usually do 2 plants but last grow i did only 1 and still got the same amount(4oz) here it is at the beginning of flower. i'll post some more current pics this evening if you are interested?
