I dont know man, im using 400watts of CFL light for my veg then adding 1 more light for flowering. im using 2 45 watt CFLs right now, and adding 1 more 45 watter later for flowering
I'm sure you'll be fine. I've used 6 26 watt cfl's to veg out 6 plants before, which is only 156 watts total. Just keep them about 3-4 inches above the plants and they will grow stocky.
