Glass temp VS Substrate temp

Well im getting ready for a new addition (maybe two?), so i scrubbed down my unused tanks and spread some fresh aspen throughout. I am trying to get my temps right, and i seem to have a difference from glass temp to top of substrate temp of 18*f. i have a layer of paper towel and about one inch of aspen. With the value i have found i would have to have the glass at 103 to have the substrate at 85. If i thin out my aspen anymore my snake wont have the option to make burrows. Is this glass temp safe or will my little guy get scorched?

It's the glass temp, directly over the heat mat, that you need to be measuring and getting to sit between 80 and 85F, as that will be the hottest place your corn can get to :) So yes, the glass temp at the moment would be too hot, which is not good.
 
So 80/85 is the preferred/optimum glass temp not substrate temp? If that is the case then what temperature should the substrate be? Im just confused, because if the glass is 85 then the substrate temps are the same throughout the viv and no gradient is observed.

Well there will be a gradient, because if he wants to get warmer, he will burrow down to the heat. Although I've found my corns spend most of their time in the middle or cooler hides, except after eating or when shedding :)

When I check the temp inside my warm hides, on top of the substrate, it is always warmer than the temp on top of the substrate in the cool hides, but then the hides I use are rather enclosed, so I suppose the heat builds up inside them :shrugs:
 
I previously measured my temperatures mid substrate, and had no problems, but i am always open to trying new methods that will improve the comfort of my animals. I finally convinced my girlfriend that theres really no difference inbetween one snake and two. I think next month i might shoot for the "This is the last one" technique. :rofl: Thanks for the insight :)
 
I wonder how many "last ones" you can get?
I keep my thermostat set so the max temp is about 87°, measured with a probe next to the thermostat probe. The warm hide has a little less substrate under it than the rest of the tank (it's just pushed in a bit).
When I set up my viv I tested for a couple days and found out that it kept the warm hide at about 83°-84°. The hide actually stays at a more even temp than the UTH.
 
Well i thought about it a little bit, and took into consideration what you said alan, and the hide doesnt really have to have much substrate in it at all does it? I removed a bit of the substrate where the warm side hide goes only leaving a little bit on top of the paper towel, and my glass to substrate temp is 88/81.5. Acceptable? I think so. Cheers.
