I have about a year and a half old Hermanns tortoise who is about 3 inches long. He is currently in a closed chamber enclosure and I was wondering about what length or age he has to be before I can make him a really awesome open top enclosure that doesn't need 80% humidity all the time? I have been searching for awhile for the answer but I can't seem to find one if you guys could help me out that would be awesome!
