I have sort of a question/comment. Let's say it is 90F outside and 80% relative humidity. If you take that air and heat it, the relative humidity will drop. The dew point will be the same. So the heaters and/or basking light lower the relative humidity. The air can hold more moisture at a higher temperature. So heating the air/viv makes the relative humidity lower.
I am not sure what is important to a bearded dragon, the relative humidity or the dew point. The relative humidity tells you how close the air is to being saturated with water. The dew point tells you the absolute amount of moisture in the air. Well, it tells you at what temperature it would form dew. I always figured that the dragons liked it hot and dry, with the heat helping make it dry.
