It measures about 5ft by 4ft, has a ceramic heat bulb, halogen flood bulb, florescent UVB light. It has a plexiglass front, and the lid is a sheet of coroplast (corrugated plastic sheet) with a vent in the top for air circulation. The humidity in there is 90% all the time. I recently moved my smaller tortoise into the enclosure with my older female and they have been off to a rocky start with each other so for now there is temporarily a board dividing the enclosure in half until I know if they are going to get along or not. If not, I am trying to brain storm on how I can turn the enclosure into a 2 level, and have one tortoise on the bottom floor and one on the top floor, it seems difficult though.. I might end up selling this one and building a new 2 level enclosure, takes up less floor space that way, I am running out of room in my house!
