  1. Keeping everything as dry as possible
  2. Extra protein for fast growth
  3. Humid areas within the enclosure ✔

Why: Merck says high humidity microclimates are often critical for dry-land species like tortoises to reduce shell pyramiding. So even a desert tortoise needs a humid spot, such as a damp hide.

Huh, didn't know that: Merck says leopard geckos also benefit from humid microclimates to help them shed.

The dad joke
Why was the tortoise good at math? It had a shell-culator.
