One ambient band, 28–32°C, dropping to no lower than 24°C at night. Same scale on every sheet here, so two species compare by eye.

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 heat sourcebecause Temperature — basking 48-52 C / ambient 28-32 C / night minimum 24 C
A thermostat to regulate itbecause Temperature — basking 48-52 C / ambient 28-32 C / night minimum 24 C
A thermometerbecause Temperature — basking 48-52 C / ambient 28-32 C / night minimum 24 C
A way to check the night figurebecause Temperature — basking 48-52 C / ambient 28-32 C / night minimum 24 C
A hygrometerbecause Humidity — 70-90% + water
UVB, stated as requiredbecause UVB — Ferguson 3 (UV index 2.0-3.0)
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.
