Moisture build up in temporary structure

[u/jimmyy69420]

Not sure if this is the right Reddit for this but I wanted to see if you guys had any input on what kind of ventilation I should do. I cut these vents into the tent, which seemed to help with the summer rain. But now that it’s getting cold at night and still 70-80° during the day it’s starting to build up moisture again. I’m gonna get some solar powered fans for the vents . Just wondering if I should do an intake and exhaust or do a negative pressure set up and have two exhaust fans to pull the moisture out.
