Hello every this is my first post and I have a 4x5x8 closet grow room and I'm having trouble keeping the humidity down, the heat if fine and stays around 70-75 degrees but I have 2 damprids in the room and I don't think they're doing anything or helping much cause the humidity when I open the door and check its around 75% which I know is way to high, so I was wandering what type of ventilation system would be sufficient for this closet grow, i have three plants in there now that is really a prep grow but I want to get this problem fixed before I start my white rhino and cheese crops which will be next week so any help would be appreciated thanks
