whitestalkslongwalks - I'm using CFLs for my grow, and I can assure you they work fine for vegetation all the way through flowering.

They may not be the best lights in the world, but when you consider the price of buying them, the price of powering them and the price of cooling them, vs any other option, I feel they're the best value solution for a small cabinet grow, and they DO work well.
