mck, you should get a copy of How to Grow 8oz. of Bud for Under $100, by SeeMoreBuds. I got a copy at my local megabookstore. Interesting reading, and very do-able! If you're at all considering a flourogrow, you should check out a copy of that book. I have several friends who have built grow cabinets using combinations of flourescent and LED, and they are able to grow up to 6 or 8 plants at a time, and they both built their first grow setups similarly to what's shown in SeeMore's book. Based on what I've seen, I think that growing 2 or 3 really good plants using nothing but CFL would work fine.
