I live in Utah, and the winters can be very dry, sometimes in the single digits with less than 5% humidity. Quality solid wood instruments will start to crack with sustained exposure to humidity under 35% or so. I have three Martin solid wood guitars that I keep in a humidity controlled “tent”. Very easy to keep constant humidity. Humidipacks in the case can help, but you really need to stay on top of your humidity if it gets too low. I would recommend picking up some hygrometers, calibrate them, and keep one in the case with the instrument, and one in the room.
