They weren't growing that fast before I put them outside
That's because you're using flouros, which basically put your plants into hybernation unless you use a shitload of them, or some big expensive ones which require ventalation.

you should allow medium to dry out almost completely before you water...this allows the plant to breath having more oxygen available to roots, and the roots in turn seek the moisture available deep in the pot.
Many people believe, myself included, that if you allow the roots to dry out as much as possible without harming the plant, they will grow bigger, faster and stronger because they are forced to grow to search for someplace that has moisture.

the CFLs are 4.5 inches away
They should be touching, if you can do so without burning the leaves. This is one of the main advantages of flouros. You should at least try. Find out at what distance the leaves start to be adversly affected (don't worry - they can take it) then move them back just a little, and keep them that far away. This will give you the greatest yield.

nothing wrong with cfl's if that is what fits your lifestyle
I agree. I didn't mean to come down on you for using flouros. I did it myself once. Also I didn't realize that stealth was such an issue. High intensity light can be noisy, at least the fans that are needed. It's just that when I swithced to HID I more than doubled my yield for the same effort.
