Ok, some more questions. The two salcata torts I just received are pyramided. I understand that at 9 and 10 inches, they do not need a closed chamber. But, if I make it a closed chamber, would that be ok for them or does it not mater at this time. Would just keeping the substrate damp and maybe a humid hide do ok to stop any further pyramiding? The pyramiding seems as though it was stoped but I would like them to grow as smooth as I can. I will upload pictures tomorrow. Also, would 24inches be high enough for the sides?
