I uploaded 4 pictures of my terrarium but cant figure out how to link them. You should be able to check my profile and view the images.

I currently do not own a BP. I will be picking him up on Saturday and want to get this perfect before I do!

I have what i would assume is around 2inches deep eco earth. I used 1 brick for the 20gal.

The heat doesn't seem to effect the cool side of the tank at all or go all the way through it.
