Setup

The numbers

Thermal gradient

152025303540 °C
24–25°Cool side
30°Warm side
20°Night

Day: a real gradient, 30°C warm against 24–25°C cool, so the animal chooses. Night: 20°C.

Why

Same scale on every sheet here, so two species compare by eye.

The sheet stateswarm 30 °C / cool 24-25 °C / night 20 °C

Humidity

80–90%Target RH

The sheet statesThe humidity rises to 80-90% overnight, but decreases to around 60% during the day.

Diet
Even adult (6-8 ft) Spilotes pullatus are never fed anything larger than rat pups or adult mice.

Day

Drag the sun. The sheet states a night temperature, so the rail follows it.

Enclosure and conditions

What your climate adds

This sheet states a range to hold. Your local climate decides how much work holding it is. Pick the nearest city: nothing is sent anywhere, the choice stays in this browser.

What it needs

A way to check the night figurebecause Temperature — warm 30 °C / cool 24-25 °C / night 20 °C
A hygrometerbecause Humidity — The humidity rises to 80-90% overnight, but decreases to around 60% during the day.
Not stated: The size of the enclosurethis sheet states no size

Every line above is deduced from a value this sheet states, and names which one. Nothing here is a general recommendation. What the sheet does not state is listed too, rather than left out: a kit that looks complete is worse than one that names its gap.

The species

National law is not global, and we hold no national wildlife law for any country, Thailand included. Check your own authority before buying or selling.

This sheet states 5 of 7 of the fields this product runs on. What is missing turns something off: enclosure size audit, day/night engine and awake count on the globe. We show the gap rather than fill it with a plausible number.

UVB is measured but does not count: it is absent from 420 of 678 sheets, and on most of them that is not a gap, since a nocturnal snake's sheet has no reason to state a UV index. Counting it would call the library incomplete without cause.
