Thermostat Probe Placement

[joepythons]

Ok, I've been looking around for the answer to this one for awhile but can't find much. I have a cornsnake and a western hognose. Where should I have the thermostate probe placed? Right on the glass above the uth or on top of the substrate? My temps are around 82-86 degrees when placed on the glass. But of course I don't get that 90-some degree hot spot. Also, I can't get my cool side temps up. They are staying around 66-70. I have a towel over the screen to try and hold heat in but it didn't make a difference. And of course my hognose seems to like to chill over on the cool side all the time Any advice? Thanks so much!

The probe goes above the UTH on the glass.Your temps are way to high for corns.The range should be 80 to 82 not 90 .
