so your saying to start off with the x4 42watts for the first #? months? and then use 2x 35watt till the end of harvest? or is it the other way around?I wouldnt. Use those up to flowering and then go to a 2500-2700k(35ish watt) cfl. You could leave a couple of the veg cfl's in there for extra light.
I would do 4:2. Meaning 4 2700k to two 6500k. You should be good.

are these considered veg or flowering light?
