Hello, I have a 40 gallon terrarium setup for my 8 inch beardie (2.5 months old). 8.5 inch dome with 100 watt exo terra halogen basking spot sitting on top of steel cage mesh. Digital thermometer only reading about 89 degrees at basking spot. I've tried a couple different 150 watt basking bulbs and nothing seems to get the temp any higher. If I were to cut out some of the cage mesh would that allow for more heat to get into the terrarium? It seems like the mesh/cage must be absorbing too much of the heat. Any suggestions appreciated as I'm new to this.
