I have a similar set up. 400 watt lights don't penetrate the plants all that well so I'd suggest a SOG or ScROG.

I just started using Sylvania GroLux bulbs and I'm very impressed with the growth under them.

If you are growing in coco, remember to treat it like a hydroponic medium, not like soil, for the purposes of pH, watering, feeding etc.
