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

Warm side: not in our data

The cool side, 27–28°C, dropping to 24–26°C at night. This sheet states the cool side only. It gives no warm side or basking figure, so the hot end is not in our data. Same scale on every sheet here, so two species compare by eye.

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 heat sourcethis sheet names only the cool side: « cool 27-28 °C / night 24-26 °C »
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.

What this sheet states

TemperatureHumidityEnclosure sizeActivityOriginDietSourcesUVB

This sheet states 3 of 7 of the fields this product runs on. What is missing turns something off: humidity instrument and audit, 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 421 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.
