Better to be realistic than paranoid but...humidity is very important. For example, I live in a quite wet climate and the humidity in a whole house is high. IÂ’ve read that the recommended humidity is not more than 50%. So it is important to check the humidity level in the room (and in a whole house). In my situation, the best decision was to buy a
whole house dehumidifier because the humidity was high everywhere and might cause different problems. If the humidity in the place where you keep your ukulele higher than 50% you may search for a small room dehumidifier (on
Amazon or somewhere else).
P.S. Small one is better because it's cheaper itself and the bills won't be so high.
