I've added furnishings:
The warm hide is on the left. It's built from a piece of cast iron water pipe sitting on a novelty cast iron frying pan and topped with a piece of slate. The cast iron modulates the temperature fluctuations caused by the on/off thermostat. A pulse proportional thermostat is high on my wish list. The cool hide on the right is just a stone mug with a cracked handle. In the back along the rear wall is a wire tunnel covered in fake foliage. It covers the entrance to the terrarium and will allow my snake to traverse the length of the terrarium under cover. The climbing branch was harvested from my local park, washed, dried and coated with 3 coats of polyurethane. I found the bench on the right in the garbage. I cleaned it and coated it with polyurethane. The fake flowers hold the probe of the thermostat that controls the RHP. The water bowl in the center is plastic. It has a wide flat bottom to keep it from tipping. Golum is a decoration that also gives the snake something to hold onto if he decides to take a bath. The lights are there just to take the picture. They are not a permanent part of the terrarium.
The substrate in the tub is 2-3 inches of shredded paper. The water bowl is a stainless steel tray. I've found that if I put more than an ounce of water in the tray, the humidity in the tub reaches 90%. An ounce keeps the humidity around 60%. The porous stone is to aid with shedding. The hide on the left is obviously a milk carton and the one on the right is an overturned fruit bowl. He'll have to burrow to get into the fruit bowl but I'm sure he'll manage it.
Let me know what you think. I plan to pick up the snake on March 5th, so I have time to make corrections. Thanks.
