Great pic of the set up. I too am struggling with temp and humidity issues and it looks like you might have the answers. What size tank is that? What watt bulb / che? By covering the top and providing heat on just one side do you get an appropriate gradient / cool side temp? I was concerned about scortching / fire hazards with covering that close to the heat source, but it doesn't seem to be a problem. How do you take care of humidity / air flow with that set up? Sorry to bombard you with so many questions just really want to get things right for her so she is comfortable and happy.
