Quick and short in my 5 tanks I have ground temps at 87-91 just above heat source. On glass at heat source 99-106, air on coolside 69-71. What do I do to get cool side warmer? I put insolated pad under tanks that did not help. Please help I want to give them. Best place to live. I am using cypress mulch to help with humidity which is now staying around 61-65%.
