I've seen a few members here do very well with CFL's.
Check out the "indoor Grow" forum on the home page.
Go to the sub-forum "CFL Club". There are lots of great post there.
I am close to finishing a CFL grow myself. I am growing a strain of "U.K. Cheese".
You can look at that through my link.
Another CFL grow that I followed with "Cheese" was by a member named "Urbanfunk".
I will attach a link for that grow journal for you also.

I'm sure someone will come by with some answers for you.
Take care.
