The top is currently covered by 2 towels up to the lamp (so like 80% of the top screen is covered) ...this also holds humidity, so at times when it got too humid I would open it up slightly until humidity dropped again. Also one side is covered with a towel to create more of a "close" surrounding for the snake and hopefully insulate the tank.
What is the bottom of the tank like? Providing some insulation at the bottom helps considerably.

Also, what kind of UTH's do you have and how are they attached?

How thick is your substrate?
