Rack Heating Issues

[NRWAR]

Hey guys so I picked up a new rack and I'm having some heating issues. NO SNAKES ARE IN THIS RACK. So I live at a very high altitude and I have to run eco earth or high humidity substrate. I have thermostat set to 93 degrees and the heat tape and everything is working great. But it will not heat the eco earth well. It won't get higher than 83 degrees. I've made the eco earth very thin in hopes that would work but no dice. I've plugged the rack straight into the wall to see if maybe my thermostat wasn't working, nothing changed. Well the racks that didn't have substrate got very hot but not the ones with the coco fiber. I'm going to try a few other substrates in hopes this will work. I'm going to try herptopia and reptichip. I've been messing around with this for about a month too. If anyone has any ideas let me know. I've never had this problem before. My other racks work great with eco earth. Thanks a bunch.


Just so I'm clear. NO SNAKES ARE IN THE RACK. I am not cooking anything.
