To be honest with temps like that outside. I dont know what the temps would end up as but this idea just popped into my head...If your running a set-up similar to mine, reverse the ventilation. Have the 435cfm blowing that cold air in and a smaller duct booster for exhaust. If u ran it that way you wouldnt need air cool hoods which does away with the glass which equals more lumens! Even do more lights maybe vertical? But you would have to see if the temps would be right.*Another scenario would be to pull your inlet air from a climate controlled room?
Another thing to look into is coil headed duct boosters. Or heating coils before the tent for inlet.
I would kill for those temps man. Any questions HMU
Sorry I never got back to you until now, but heres what I ended up doing...
- had the 6" inline pulling heat from the hood, out of the room, then into my home to help with heating costs all winter.
- had a 4" inline pulling air from outside my home (0-30 degrees) thru a set of ducting to let it warm a bit, then into a home made diffuser in the corner of the tent to disperse the air.
- I run the 4" intake on a titan controls temperature sensor to kick the fan on and off
This set up worked GREAT the last 8 months with out ever having to run A/C... we'll see what temps do during the summer, I expect to be setting up at least an 8k for the hottest 60-80 days
