Ask the humidity experts I have a small dressing room where I started to store my acoustics according to the suggestions I received in this forum. I put a small automatic whole house humidifier there I set it so that my hygrometer in the cabinet fluctuates by 45%, while the rest of the house is around 30%.
Since the room is quite small, I prefer to store the guitars in their cases to avoid random things. Inside the box, the hygrometer reads a humidity similar to 45%. Is there a problem with keeping the guitars in their cases from a moisture perspective? Would the humidity inside the box really be the same as on the outside? Would condensation form in homes?
