Don't use the gro-lux. There lighing is too far into the blue spectrum. If going with flourecents, they say the best is just regular cool white with regular daylight bulbs, although I have had good success with all cool white. I know use HPS but for smaller grows Flourecents are fine. Hope this helps a little.
