Get a good 600 HPS for flower, or at the MINIMUM a 400. Anything smaller is a waste of time and money for a grow of that size. You will be seriously disappointed with flouros.
This is very true. Don't take it lightly. You will be dissapointed if you don't use at least 400 watts. I suppose you could get 400 watts of red spectrum flouros, but for about the same price you could just do it right and get an HPS and the ventilation it requires. 400 watts of fluourescent light gets pretty warm too. You will need some good fans and ducts.
