I first put up 4 42W cfls. But on advise from a coule sources, I replaced 2 of those with cool whites. Soft white=3500k, cool white=6500k, warm whites=2500k. So at 3500k do you think it's okay to flower using the soft whites cause the 3500k is close to that optimal 2500k? By the way I'm going to put one of those 42W bulbs back in with it's own extra socket. I figure the more, the merrier.
