🏠Housing a Corn snake: 110 × 50 × 50 cm, 28-30°C basking
Corn snake : A 100 to 120 cm terrarium for an adult, a thermal gradient from 28-30 °C on the warm side to 22-24 °C on the cool side, aspen or coco-soil substrate, at least two hides. Every gap must be sealed.
In short: 120 to 150 cm as an adult, 15 to 20 years of lifespan, beginner level. Docile, a rare biter and forgiving of small mistakes — the reference beginner snake. It is a master escape artist: the smallest gap in a poorly sealed terrarium is enough, so every crevice must be blocked.
110 × 50 × 50 cm and a strict thermal gradient
For an adult Corn snake: 110 × 50 × 50 cm minimum, with a basking spot at 28-30°C and a cool zone at 22-24°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: no mandatory UVB for this species, though a weak tube remains a plus according to recent references. Humidity held at 40 to 50% — 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 somewhere calm: the species sleeps by day and hates vibrations.
Frequently asked questions
What enclosure size for a Corn snake?
110 × 50 × 50 cm minimum for an adult — sized for the adult from day one; a juvenile does fine in it with extra hides.
What temperatures for a Corn snake?
Basking spot at 28-30°C, cool zone at 22-24°C, all on a thermostat with a natural night-time drop. Humidity sits at 40 to 50%.
