cant maintain a high temperature in glass cage

[jackiechan]

I'm surprised no one mentioned this yet. The thermostat probe should be directly touching the heat source. I.e, the probe should have been placed on the bottom of the tank, with the heat source taped ON TOP or it, or you can use tape (aluminium tape works best) to tape your thermostat probe on top of the heat source.

The thermometer probe should be right above (or just a tiny thin layer below) the substrate.

Other then that, I was going to suggest thinning out (A LOT) of your substrate, but someone has already mentioned this.

Good luck.

I started off with my thermostat probe directly on top of my UTH. The thermostat would turn off everytime it hit like 92 but that was the problem. It was 92 at the glass... But above the substrate inside the hide it was only 80-85.

The reptile store guy told me to place the thermostat probe above the substrate, this way the thermostat will make the uth heat up the cage entirely until its 92 where the probe is.

I would double check your temps with another thermometer to rule out if its a problem with your other thermometer or a problem with your thermostat. What thermostat are you using? Cheaper ones, like Hydrofarm, are crap and not very accurate in my experience and take a lot of tweaking. I have NEVER had a problem with my Herpstats and they are always within +/- 0.5 degrees, although its usually closer than that. They are pricey, but worth every penny.

Another possibility could be your heat mat going out. Probably unlikely, though.

But as Dr. Del said, you can insulate it and that will help. Glass tanks are notorious for being a PITA to regulate temps.

If you're worried about humidity, just mist the cage a little more often or add some sphagnum moss or cover part of the top with a damp towel.

I just got everything brand new in package 2 days ago. And my thermometer earlier tonight. My thermostat is zilla from petco.. Like ~ $50
