Help me with my grow room (need ideals)

Hello im finishing up on my first indoor harvest (ALL medical Live with 3 people who all have their cards including me)

I need some help on how to maximize my grow room. currently i have the lumex duel 600 watt ballast with both hoods in a 4x8 grow tent with one hood on both sides. I also now have a separate 1000 watt magnetic ballast with a batwing hood. Are first ideal was to use the 2 600 watts for flowering in the room and get a separate tent for the 1000 watt as a veg room, is this the most productive way? At the end of my first harvest using the 2 600 watts i had like 9 or so plants under each one and used humbalt nutrients all the way, i have multiple decent tops on all the plants with only a few standing out as bigger yeilders but nothing compared to other peoples this harvest seems like it will be alot smaller then i thought. So im wondering would it just be more productive to put the 1000 watt in the tent with the 2 600watts and just do one massive grow? About 2200 watts in a 4x8? which would eventuarly be more productive? Or any other ideals/tips??

i would go down the road of using the 1000 watt for a veg room, and the 2x 600 watts for flowering,
ensure adequate ventilation and if possible use a metal halide for the veg room,
this way you can cut your flowering period in half,
