I'm having trouble with condensation in the walls. Next time I'm going to concentrate more on making the walls air tight. I don't think I'll use drywall at all. I'm thinking more like those shower wall panels with all the edges/corners sealed. Maybe some wood panel of some type under that just for structure but the inside surface I want to be water proof and air tight including sealing the switches and plugs. I want to control all ventilation through a duct and not have any seep of even a little warm snake air into the walls where the outer edge will be much colder causing condensation.
