I have found that there is a major difference between the temperature measured on the glass (over UTH) and on the substrate in the same location. My warm side concerns me and here is why...In order to get the temp in the warm side hide to 92, the temp measured on the glass needs to be ~104. I am using about 1/2" of coconut fiber as my substrate. I have placed my hand on this 104 deg glass and it seems a little hot, but It will not burn me no matter how long I leave my hand on it. Do you think this is safe? The only way I see to avoid the possibility of the snake contacting the glass is by going to carpet, newspaper, or paper towles. The tank is on display, so I prefer not to use these, but do I have any other option?
