Just curious faded, did you ever use the same light without cfl's? Reason I ask, is I was going to supplement with CFL but not for more watts, just more light spectrum. If so did you see a noticable (and worthy) change in how the plants reacted? Also what spectrum on the CFL (blue red etc.)
First grow I did was with the V240 LED panel and I added a 300w 9U CFL Red and a 125w red/blue CFL. I had to keep the temps up and the plants were autos so the CFL's did the job perfectly. I'll get the big one back in once winter is here again. Couple of pics of my first grow below,

Day 67 from seed.

Lights off.

Harvest day
The next grow was only with led's but they were shit clones so the one I'm doing now will be the decider for me. I did notice that the plants preferred the CFL's to be no closer than 3" or the leaves started browning. Plus with the CFL's I had to wear sunglasses, led's I just switch a white light on and no problems
