Tortoise vivarium help?

The habitat should be large enough to allow for both a warm end and a cooler end so your tortoise can move around within it to regulate its body temperature. Lights should be mounted over one end of the enclosure to create a basking area of 90° to 95° F directly under the heat lamp. The cool end, where the hide is to be located, should be in the low to mid 70's. Food and water dishes can be placed midway between the warm and cool ends.

A note about the enclosure:

Glass tanks aren't the best choice for tortoises. They overheat very quickly, have poor air circulation, and are stressful to tortoises who may constantly try to get through the glass. Better housing options are a large Rubbermaid storage container or a "tortoise table," which is just a topless wooden "box" with lots of floor space. You can build one out of an old bookcase laid on its back with the shelves removed.

Uh what now..?
