I have two exhaust fans, a 1050 cfm 10" can fan, and a old 750 cfm 10"vortex running out of two seperat Carbon filters and Y into one exhaust outlet. I may have to run another 1050 can fan and filter because of smell.We're in the same boat, but i'm in the southern portion of your state. You're lucky to have a lot lower ambient temps during day and night. You're using drain to waste, which will make it a lot easier.
In my area, with 6,000 watts, sealed room, and CO2, one exhaust fan is far from sufficient
I'm also running 2 800 cfm fans from a carbon filter in the veg room through the lights in the flower room.
I had a 20k BTU ac for temp but the p.o.s broke. I am getting a new one but need to make sure it recirculates the air instaed of dumping the room air outside unfiltered. I have been looking at the 20,500 btu LG at home depot for $499. From what i can see it has a ventalation setting that you can close to recirculate the inside air instead of blowing it out of the room.
Edit: addition: room is about 4,600 cubic feet. and conceted to a 3,500 cubic foot veg room by a playwood door.
