OK I have 4 girls in flower, humidity at 64% in my grow tent in attic , Vent, fans & exhaust all seem good, would setting up the dehumidifier in the attic reduce the RH% by much, if any.
Cant put in with grow as there is no room.
I'd pop it in the biggest (cardboard?) box I could find, make an inlet near the bottom and an outlet near the top of the box and duct it to the tents intake! Set the humidity in the box below whats needed in the tent.
The box would ideally be a few times larger than the dehumidifier to let it work and/or the openings inline with the flow of air through the device
