No it is not. That enclosure is too small for anything but a tiny hatchling. Your tortoise needs something about 4x8'. You tortoise also needs a proper water bowl, a food dish, and a hide or two.
Wow Jbrez that's impressive! I'm curious do the plants you have in there get eaten and trampled by your Russian?
For TL2000 I do think your torts enclosure looks to small for her (?) happiness and health. It also looks like she (?) needs a basking area, or is it just not in the picture?
