🏠Housing a Hermann's tortoise: 120 × 60 × 30 cm, 32-35°C basking

Hermann's tortoise : An outdoor enclosure of at least 10 m² for an adult, with buried fencing as it digs, an insulated shelter and a frost-free hibernation area. Temporary indoor housing: a tortoise table with basking lamp and strong UVB.

In short: 18 to 25 cm as an adult, commonly over 50 years of lifespan, intermediate level due to legal obligations and hibernation. A hardy, endearing land tortoise, it calmly patrols its territory but remains a display animal that dislikes handling. The terrarium dimensions above are only for a stopgap tortoise table: the real standard is a secure OUTDOOR enclosure of at least 10 m² with a frost-free hibernation area.

120 × 60 × 30 cm and a strict thermal gradient

For an adult Hermann's tortoise: 120 × 60 × 30 cm minimum indoors — though an outdoor enclosure remains the serious standard for land tortoises, with a basking spot at 32-35°C and a cool zone at 22-25°C. That gradient is not comfort: it is how a reptile regulates temperature, by moving. No cool zone means overheating; no hot spot means no digestion.

Heating, UVB, humidity: the technical trio

Heating ALWAYS runs through a thermostat — the least negotiable equipment in herpetoculture — with thermometers at both ends. On light: a UVB tube (10-12 rating for desert setups, 5-7 for tropical) spanning a third of the enclosure, replaced every 6 to 12 months even if it still lights up. Humidity held at 40 to 60% — excess humidity harms as much as a deficit in a dry biotope, checked with a hygrometer, not by feel.

Substrate and layout

A dry, diggable substrate (packed soil mix, never calcium sand), two hides minimum — one warm, one cool — and a structured background for security. Place the enclosure out of direct sun, which would turn the volume into an oven despite the thermostat.
