Hey Im pretty new the world of growing but I too went the CFL route. I have 7 26 watt 6500k, 2 65w 5000k, 1 42w 2700k and four nice little ladies growing. I would recommend at least 4 of those 42w's bulbs and mix up the spectrum a little bit, kind of like real life. I just dont think the mother will be getting enough lumen's. Any way good luck. PS what strain is she?
