I have a small shed area, about 42" x 19' interior dimensions. I store tools there and would like to control the humidity. The space isn't insulated, let alone cooled/heated. I am willing to insulate the space but maybe I need some device to lower the humidity?
The good news is it can be done. Insulate, weatherstrip, caulk. If you want to reduce humidity a dehumidifier will work....but only in above freezing climates. The other alternative is to heat it and air condidion it.
Do you want it your way or the right way?
