Thanks very much for the comments, Mike!
Regarding the lamps, I use only 2 there because there is no way I can keep this cage cool. With no vent holes it is a green house inside there.
Perhaps in deep winter I can add the last lamp.
In mid summer I had to switch those 2 lamps off all the time, leaving just 1 basking spot and it was still hard to keep everything below 85F.
I didn't want to take chances with cork sheets in the walls. I don't know if you saw, but when I showed I was building my cage with melamine MDF I was yelled at by everyone.
What I did was covering the inside walls with 3 layers of this greenish epoxy paint and followed Krusty's model using screen, so it would allow for the walls to dry out.
Climbable walls are almost a need for these guys, they spend most of their active time like geckos (here, at least).
Thanks a lot for the kind words.
