you should invest in leds instead of your cfls.
you seem to have at least a basic understanding of electronics and with a little bit of research you should have no problem building your own LED rig for a decent price that would shit all over your CFLs.
the reason I suggest this is because it will save you a a lot of space inside your PC Case allowing for more growth/bud.
also it would give you more luminous intensity meaning denser, heavier nuggs.
also it would allow for a MUCH better color spectrum giving your plants more usable light and a lot less wasted light.
you can pick up Red 660nm and 630nm and Blue 450nm and also warm 2700k and cool 6500k white leds on ebay for stupid cheap.
also if you wanted to just stick with whites CreeXML 2700k WarmWhite and 6500K CoolWhites are extremely efficient and can be run up to 12watts without needing serious cooling.
I would suggest a combo of almost all CreeXML 2700k WarmWhites w/ like 1 6500k CoolWhite and an OSRAM SSL 660nm module for supplemental red light during flowering.
All of these can be obtained here:
www.LED-Tech.de also look into
www.LEDgroupbuy.com and
www.intl-outdoor.com
This would give your plants a perfect spectrum. You wouldn't need much to light up that case.
I would get a longer tray/pot close to the size of the entire bottom of your case to maximize your root zone.
Also, you should look into a taller server tower.
and for an LED rig I would power (drivers) everything externally (kinda like your doing now), your parents would never know the difference.
All in all, I like what I see and wish I would have done something similar years ago when I was still living at home.
Hope you have some nice seeds and only the best of luck to ya kid. Welcome to RIU btw.
