Either these colors or plain white. Maybe put 1 blue and red in their respective boxes?
6500K(blueish light) for vegging and 2700K(reddish light) for flowering
Don't go by the wattage. 4 x 26w cfls (4 x 100w equivalent) does not equal a 400w hps, not even half of a 250w. Cfl's are also notorious for slow growth and producing light, wispy, and no-so potent buds when there aren't enough of them. They also need to be repositioned often as they are only effective a couple inches from the plant.

Also why have many boxes when you can accomplish what you want in one?

I'd say look into a 250w hps from the start, but some people need to learn from their own mistakes :jointsmile:
