I built a tub rack to keep our QT snakes in.
We do not have anyone in it yet as I am waiting on the new RB VE200 stat.
I do have it up and running on a dimmer just to have everything warmed up and make it easier when the stat is installed.
My question is:
What hot spot temperature do I set it for??

I am getting 2 different readings depending on how the tub is set up.
Reading #1 ranges from 91.2 to 93.1 on all seven levels **With the temp sensor completely taped down over the hot spot.**
Reading #2 ranges from 83.5 to 85.8 on all seven levels ** with the temp sensor just held down with a 1/4 inch piece of tape.**

I am not planning to keep any tape in the tubs once the snakes are in them but like I said, I wanted everything set up right. I would think that the "fully taped" temp would be the correct one because it would best simulate a snake laying on the hot spot BUT I have been wrong before.

So should I leave the temps as set OR do I need to bump them up a little?
