Should I be worried about CO2 pressure build up in my fermentation chamber. This is what I have so far. 3/4" plywood cabinet sealed with silicone caulk, a layer of 1" XPS insulation with foil tape in corners. I have a door that I made with 1/2 overlay hinges like a standard cabinet but I think I’m going to redesign it to something that will seal better. I’m wondering if I create an air tight cabinet if I need to worry about pressure buildup. If so how should I vent it?
