Hi there, my grow room setup isn't much, i had a spare bedroom with a big closet which i use as my grow room. I leave both closet and room doors open and make sure all windows in the house are open to ensure airflow. The problem is i live in an island and humidity in winter never gets lower than 75-99%. My ladies are in veging right now, but preety soon they'll be flowering and i don't want mold destroying my grow. I read in some posts here that exhaust turbines don't help when outside climate has high humidity. Any advices guys?
