Maybe you all can help me out here. As far as I know you want the humidity in the room you play guitar in to be 45-50% {+/-5}. In winter when your heat comes on this causes the guitar to dry out so you should keep it in your case with the humidifier.

Well, how do you know what the humidity is inside your case...? and would placing a humidifier in your room also solve the problem? Also what happens in winter?

If the humidity in your playing room reaches, let's say 65% you need to break out the humidifer, but what if it hits 35%?

If you all can help me understand this at all it's appreciated.

I think you will find all the answers you need if you simply google and look up the difference between a humidifier and a dehumidifier.
