With the right set up...space n light configuration....cfls can give u plants that will stand up to plants grown under HID or LED...w cfls it's all about the space Ur trying to illuminate... light placement is key...I've had 600 watts of cfl in a 3x3 space n put out quarter pound+...
If u don't pull at least a pound off that scrog I'll b suprised....it's gonna b pretty as hell round week 6...5x10 of nothin but tops...it'll b nice...b even bttr if u let the plants get bigger before u flip em next round...
