Thanks for all the tips everyone. Here is a picture of the completed setup, minus some minor rearranging once my fake grassy shrubs get here. I will definitly look at including a thermostat in the future as a precaution, but temps seem perfect for now.
I am using a 50w Heat Glow exo terra light as the only source of heat, set on a 12 hour timer. 7am to 7pm. There is not a lot of natural light gets into my house, so I've gone this route.
I was planning on using a 15w heat cord below this enclosure, but temps seem pretty ideal right now as it is. Im only running 12 hours of heat a day, would anyone recommend the heat cord for night heat?
Temps on the rocks are about 35 degrees and at the other end vary between 26-28 degrees depending on ambient temps. This has been monitored for several hours in the heat of the day and seems very stable. The reason I prefer this method to a setup involving a thermostat is that there is less chance of any sort of failure.
I stayed up to observe the snakes behaviour in the new enclosure, spending the first 6-8 hours trying to escape I assume. Eventually he/she tried to get through the gap between the 2 sheets of glass, and was successful. I let it get about 1/3 of the way out before gently alerting it to my presence and it retracted its neck. I then folded some cardboard in half and stuffed it in the gap to prevent any future escapes.
Appreciate any feedback or decoration ideas.
Cheers,
Patrick
