>>ok, I have a heat pad, right now with winter 1 light keeps it at about 72, and the tank heater alone keeps it about 75
I use the stick on under the tank heaters, size aprox. 8x8 to 10x10 which is located on one side of the tank and keeps the substrate about 85+ degrees. Put the light(15 or 25 watt) on the other side of the tank. Put a thermometer in the Tank and monitor the temps in different areas with the light on for about 5hr. You will have to play around with the size of the bulb for air temp, but it sounds like you need more belly heat than what you have. It also depends on required heats for what kind of snake your keeping.
Overall your snake should have a warm area 80-85 degrees and a cool area 75 or less in the tank at all times it can retreat to.
