The only problems I've ever had was trying to keep humidity up on aspen bedding. Since I'm on Cypress now I think I should be better off than I was. Also once I have the plexiglass it'll hold some of the heat better so it shouldn't fluctuate much except when I turn the lamp off at night. Really I'm just looking to see if it's good or what I could improve. If I had my druthers I would have given it a few weeks before I got the snake just to make sure everything was set up right and everything was working right.
