Hi all, I am working on a humidor cabinet and am getting ready to install the Spanish cedar paneling. It’s at 8% moisture content right now. The RH in the cabinet will be 70% after it’s installed an has the humidifier in it. How do I calculate what MC the wood will be at in 70%RH, so I know how to appropriately gap the paneling? The paneling is 3 5/16” wide with a 5/16” tongue. Thanks

As I look at the calculator, it only gives you calculations for MC changes. I need to know what MC it will be at a specific RH. How do calculate that?
