Setup

The numbers

Thermal gradient

152025303540 °C
29–32°Cool side
35–38°Warm side
21–24°Night

Day: a real gradient, 35–38°C warm against 29–32°C cool, so the animal chooses. Night: 21–24°C.

Why

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

The sheet stateswarm 35-38 °C / cool 29-32 °C / night 21-24 °C

Humidity

50–60%Target RH

The sheet statesHumidity should be maintained at 50-60% with occasional misting.

UVB

Requiredrequired

The sheet statesFull-spectrum UVB lighting should be provided for 10-12 hours a day.

Traceable. The figures above appear in the page we cite, which we opened on 10 Aug 2026. That means you can check them, not that we have confirmed they are right. exoticssource.com

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.

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.

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 4 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, the diet section. 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.
