My Flower room is about the same size.
32"x80"x10feet tall and sealed with Temps from 2 600w lamps averaging 85+ degrees.
Heat was a limiting factor in my ability to run anything over 2 600w lights on full power so... I wanted to increase the air circulation in the room spectacularly!!
I built a 4 inch raised sub-floor in the room. I used a hole saw and cut 3- 6 inch evenly spaced holes in the floor and placed those cheap 6" inline booster fans in those holes with the direction of flow pointing up.
I then used the white wire shelving at 18" above the floor to sit 7 gallon "SmartPots" on.
This set up draws fresh air from under the door and under the floor and pushes it up through the canopy from beneath the plants and pushes the hot air from the lights to the ceiling.
I also figured it would help push the CO2 up into the canopy (since it is heavier than air).
I also have a single 8" Vortex fan with a Phresh Filter hanging from the ceiling drawing the hot air COMPLETELY out of the room.
Now Average temps ~70 degrees with 600w HPS/1000w MH/600w HPS... all running 12/12 at 100%
YMMV

Dim-able Digital Ballasts that run both HPS and MH bulbs
I have 2 600w and a 1000w dim-able digital Nanolux ballast in my 32"x80"x10 foot tall Flower Room.
I also have a 600w Nanolux in my 36"x24"72" veg Cabinet.
I usually perpetually grow 3 plants at a time from clones so I veg for 4 weeks.
At all times there are 3 plants flowering and 3 plants vegging.
Over the yrs, I've found that anything more than this leaves entirely tooo much cannabis laying around.
So I typically put the fresh small clones in the Veg cabinet on day 30 of whatever is in my flower room.
VEG->First week or so in Veg Cabnet: 600w Nanolux turned down to 50%--> 18/6-- HPS bulb to stretch them a little and give them some height.
VEG->Second week or so in Veg Cabnet: 600w Nanolux turned down to 50%--> 18/6-- MH bulb to stop stretch at around 20" and to get them growing thick/bushy
VEG->Third week & Fourth week: 600w Nanolux turned down to 75%--> 18/6-- MH bulb --> Topping/Lollipop/etc
FLOWER ->Day one of week Five: Moved from Veg Cabinet to Flower room and put under HPS 600w/MH 1000w/HPS 600w all at 50% for 12/12. (+/- SCROG NET)
By the end of the 5th week... HPS 600w/MH 1000w/HPS 600w all at 75% for 12/12.
By the end of the 6th week... HPS 600w/MH 1000w/HPS 600w all at 100% for 12/12.
Great yields...!!!
YMMV
