OK...some of the things you bring up are gibberish to me. Only my second ever indoor grow (first one was almost 10 years ago). Pardon my ignorance, but I know nothing of the pruning techniques you speak of.

My area is a simple closet that contains the boiler and hot water heater, about 5.5 feet by 5.3 feet. The 400-watter worked really well for the last grow, and I figured the same would do just fine for what I currently have. And the two 300W CFs seem to provide a similar amount of light than the HPS I once had.

Are you saying that once my new unit arrives that I should also use the CFs to supplement the light?
