I don't think it is ideal, but it will work. The big problem is that the sun is much more intense, with a wider spectrum, and a lot more UV. Switching to CFLs is a big change, plus if you have other plants indoors you can bring pests, mildew, or worse in with your plants.
I did a small grow. after taking out the males im down to two. they actually are outside plants. they been outside since seedlings. the change came when i added the flouresants, so the plant could get more light even after the sun goes down.
