600 hps + 400 MH or 600 hps + 400 hps

ok my veg room is going way to fast for my flower room, some of my plants are 2 ft tall way too much, so this is what i am thinking.

i have,
1 600 watt digital electric green house kit from HTG i only have an hps for that
1 400 watt ultmate from HTG that is hps and it came with a MH conversion bulb
so i can use ether hps or mh
i wanted to put those two in my flower room and for a month or 2 i will use.
i have 3/ 2 blb / 4 ft florescent ballests
i have 5 full spectrum sunshine blbs and 1 plant aquarium blb to use in veg

PLEASE TELL ME YOUR THOUGHTS

How about the 400mh in the veg room and the 2 600hps and the 400hps in the flowering room..............scrap the floros..use them for your clones.............
