He is using 200w CFLs, that equal out to 40 Watts each.... Anon you aren't giving them adequate light and they are stretching, additionally CFLs only give off certain spectrums of light, I am growing with CFLs myself, Currently i have 18 of the 100w CFLs "23w" ... which would mean 7 more of your bulbs, Plants require 7000+ Lumens, you are giving them to little, additionally because you are using CFLs, the light doesn't penetrate as well, you should put a few CFLs on the sides. You aren't even using 100W of power to feed this light hungry monster.
Solution:
Buy some of the make your own lamp kits from Lowes / Menards / Home Depot. The ones with the Chain, Dangle on of these with 2 100w bulbs on each side of the plant at different height levels, this will increase your yield by HUGE amounts. hold on let me show you the light I am putting off.
