I would have stuck with the cfls for vegg and got an HPS to flower... You don't need anywhere near the amount of power in lumens during vegg. I use a 150watt 6500k cfl for vegg with 2 32wtt 4500k cfls, which is freaking amazing! And then when i switch to flower in goes my 400w hps. Really cuts down on the electric bill, plus im not wasting light, a 400wtt system for veg, in my case would be serious over kill. I always try and get the best setup that suits my needs. I would definitely try and get a better bulb to flower with tho, u need to be well below 3500k to get results worth putting all that money and effort into. Not trying to be discouraging or anything but dont expect to get decent buds without the red side of the spectrum
