I really would like to get rid of the bulb, because like you said, it seems like that is sucking out my humidity. Do you think my UTH, that I have on the side is enough to keep the temperature were it needs to be? I guess the only way to check would be to not use the bulb? I would just hate to subject the snake to a sudden drop in temperature . Here is a link to my UTH.
