How to lower humidity

I was having same problems. I bought a 10l dehumidifier and not a single problem since. Hope this helps

A simple solution for me was to create air flow going into the tent, exhausting out to the room towards a window I leave slightly cracked. It will let some cold air out but it also sucks the humidity out. It's not ducted to the window. It's a few feet away from my tent. With a 1 in crack in the window I drop about 5-10% humidity. If I crack it open 4 inches my humidity goes to 35% This isn't an option if you don't have a good carbon filter. I vent heat directly back into my grow room that as a AC unit built in the room not the tent. I just let natural air flow exhaust my humidity.

You will need to control the humidity outside the tent. Get a house dehumidifier. The problem with small cheap ones are they work very little and when your exhaust fan is running, it just keep bringing in the outside humid air.

ONE WAY YOU COULD DO IT IS BY JUST RAISING THE TEMPERATUR, BUT THATS BY FAR NOT THE BEST SOLUTION.
