In my Savannah monitor enclosure I have a pretty good temperature gradient:In his basking spot the temp is 130 directly under the light and about 110 to the sides. His cool side is about 78 degrees and under the basking spot in the shade area the temp is about 85. What I am wondering about is the humidity levels. In the shady part of the enclosure (under the basking spot platform) the humidity is somewhere around 90% in the basking spot it is 70% and the rest of the cage is between 60 and 70%. Is this enough variation? Should the basking area humidity be lower? The enclosure gets decent air flow but I think I need a high vent to bring down the humidity a bit. Thought?
