I think you're missing the question here. I understand completely about veg cycles and all that. He wants to veg under the 1KW AND flower, but the 1K will burn the seedlings or so we were told.

I'll still have about 3 feet or so if I keep them at 20", so I don't think it will be that big of a problem. I am still wondering if the three fans will be enough to keep it cool, though.
