All I monitor humidity for is to make sure it's not getting too low, anymore. As long as there's no condensation, I'm not worried. My average humidity is roughly 50-60% most days but will sometimes drop down to 40% if it's cold outside and sucking up all the moisture. As soon as I see pink belly I start spraying down for shed. High humidity is better than low humidity, especially if you're having trouble keeping the ambients up.
