Hey cool mini PPK grow! I've never flowered with cfl. your results look better than I'd expect!
waaaaaaay back I bought a 250w lumatek digi ballast and both hps and mh bulbs. You can still get them, both the bulbs and ballast are widely available.
If you ever try it you will find the mh bulb is significantly hotter than your current setup but.... the 250 w hps bulb is not that much hotter than your current 4-bulb cfl setup (I've used cfl for rooting and early veg stuff plus bonsai moms).
the difference in results will be significant.
I grew at a facility with hps and mh but at home I used to always have a couple plants in the bedroom. I would surround them with 26 watt cfl blue and orange lights. I definetly know what the appeal is with those cfl lights. You know, those lights emit a small amount of UV radiation. I know some people might disagree but Im in the Ed Rosenthaul school of thought that UV-B is great!!!!

There's a thread by Riddleme in the forums showing his technique for bringing out early amber in some strains. He's a big believer in additional UVB's during all phases of growing. As a matter of fact, he uses the exact same bulbs for flowering as he does for vegetative growth. He's added a substantial amount of blue wavelength with a variety of blue aquarium T5's. His grows are simply amazing for using nothing but T5 flouros.
