Yeah I used 6 CFLs on my last (soil) grow and I counted 100+ buds, some of which were as big as your biggest one there (to the OP of this thread) and some smaller like the size of a blueberry. It all depends how close you get the lights (and of course other things) but with CFLs it's about getting coverage and proximity - CFLs die off quickly after a few inches away!!
I harvested the one bagseed plant (6 CFLs, in soil) after 12 weeks of flowering and fighting hella high temps (90-100). I got just under 2 ounces. I used FIM and LST'd like crazy. It was like a SCROG but w/out the screen.
