Heat control

Hi everyone. I know of friends here in canada who have had 5000 watt grows with only intakes from outside and exhaust. I will be doing about 5000 all in. Including led lights. I have an intake and an exhaust this will be in a out building. Would I be able to get away with a portable a.c along with my other equipment? Thanks for your tim3

If you’re in Canada and run lights at night pulling in cool outside air, I would think you would generally be okay if the temperature was lower than 65f outside without any kind of AC.
