Quick Growing Lights Question

Hey guys,

I am making a PC Grow Box and I have a couple quick questions about lighting.

So what do you guys think of these lights

For Veg: 3 of cfl 26w 6500k ( http://www.elightbulbs.com/LongStar...ist-Screw-Base-Compact-Fluorescent-Light-Bulb )

For Flowering: 3 of cfl 26watt 2700k ( http://www.elightbulbs.com/LongStar...ist-Screw-Base-Compact-Fluorescent-Light-Bulb )

what do you guys think is this good for a decent yield or do you think I should add one more light or do you think a plant or two will survive with that much light in my grow box

if I add one more light would this 42watt cfl be good ( http://www.elightbulbs.com/Litetron...ist-Screw-Base-Compact-Fluorescent-Light-Bulb ) or should I go the cheap way and just get an extra one of the veg & flowering lights

I usually run 2 high K bulbs for every one low K bulb when vegging and the other way around when flowering to give them a mixture but that is just my opinion

So I should save some money and just get 2 high k and 2 low k and that should work for me ?

It'll work fine. I would recommend keeping a mixture but for veg use mostly 6500k's as they promote more stem growth and for flowering use mostly 2700k's to promote more flower growth.
