yea I use the CFL's all the way through. This is my 3rd grow with these bulbs... I'm very suprised at the life of them. Although i think 3 of them will need replacing for next grow...

For flowering, because you need red spectrum. I've introduced incandescent 100watt bulbs.. This isn't the best source for red spectrum.. at all. If you can use a MH or a HPS .. by all means... DO. But for limited space, money and knowledge.. incandescents are not a bad start at all. The only issue with them is Heat. Keep the heat down with constant airflow, and you can do alright.

Practice makes perfect, as we all know. The best way to start .. for anyone, in my opinion is using Compact Fluorescent Lights...there's alot less room for error.
