Ever get the feeling your caught in the middle of an episode of "He said, She said" where nobody's completely wrong and nobody's absolutely more right? It's better that talking about politics I guess. And klondike, I think it all depends on the dimensions of your grow room, but more light=better, like maybe 1000W hps for a big grow like that. But I'll leave that to the techies. For 5 cool, for 10, bigger, I think.

Qs on lighting a new grow space from KB (split from light info sticky) i plan to grow approximately 5-10 females in my next grow and want to swap the cfl setup for a more efficient HPS one. would a 400watt be a good choice, and how much would the bulb, reflector, and ballast cost approx?
