Good morning Kvlt and Meg!!!
No, those are not both heat lamps. The one on the left is a ceramic heat emitter, the one on the right is a 9W compact florescent bulb set to a 12-hour on, 12-hour off cycle.
I agree 91 degrees is a tad warm but right now I am just trying to calibrate my new thermostat. I am trying a couple of different configurations at the moment.
However, I keep going back and forth on this because I hear leaders in the industry state that they run unregulated UTH's and regulate the UTH by how much aspen they put over it. They also suggest that to all of their customers. On the other hand you have many folks state they should put their UTH's on a thermostat and set the temperature to the mid 80’s. It’s been my experience that this one topic is probably the single most difficult to get a consistent answer on in our hobby. Soooooo, I will put the probe to my thermostat on the glass and set it to around 88-88.5 degrees with the hopes that the mid to top layers of substrate will be in the mid 80’s. More experimentation is needed at this point.
I also agree, and it has been my experience, that ceramic heat emitters will certainly dry out the air within the viv. With a full water bowl I can get my humidity up in the 30% ranges but plan on adding at moist hide during times of shed.
The reason for the ceramic heat emitter, and Kvlt living in South Dakota you can appreciate this, is I have a hard time keeping the ambient air temperature of my viv warm enough. The viv is on the lower, cooler level of my house, and in the winter that temperature is usually 66-68 degrees during the day falling to 64 at night. With my first snake, I experienced one regurge in short time I had him and he subsequently didn't make it.
No animals were harmed in the setting up of my viv…….
I certainly do appreciate all of the comments.
Regards,
Steve
