Ok, the size for my male ball python is going from a 4x2x2 to a 4x2x2 and use a layer of soil and forest floor. In current enclosure temps and humidity stay in appropriate ranges. I think that's originally why I did the plexiglass at 3/4 of the length. I will likely just get it set up and test it to make sure it's the same as his existing then I can relocate him. My female will be the issue foe another day, I am moving her into a 6x2x2, I haven't built that yet. I guess I did answer my own question lol
