Warm side: not in our data

The cool side, 26–27°C. 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.

The sheet statescool 26-27 °C

Humidity

65–100%Target RH

The sheet statesHumidity Management Humidity needs to stay between 65 to 100 percent.

UVB

Requiredrequired

The sheet statesZoomed T5 5.0 ReptiSun bulbs running the full length of the enclosure provide appropriate UV exposure.

Diet
Create a focused basking site using a halogen bulb positioned 8 to 12 inches above primary resting branches.; Feeding Schedule by Age Juveniles under 12 months: Every other day, 4 to 6 insects Subadults 12 to 24 months: Every other day, 6 to 8 insects Adults over 24 months: Every other day, 8 to 10 insects plus week...

Drawn from the stated numbers. Only what the sheet states is drawn inside.

Why

The rectangle carries the exact width-to-height ratio of the figures above it, and the ruler under it places that width on the 0–250 cm scale every sheet here shares, so two species still compare at a glance. Nothing is added that the sheet does not name: a lamp drawn on a sheet that never mentions one would be invented equipment. What the sheet leaves out is listed rather than left blank, because an empty tank reads as « none needed ».

The sheet statesAdult practical minimum around 120 x 60 x 120 cm, with additional height preferred for this arboreal species

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

Enclosure at least 120 × 60 × 120 cmbecause Enclosure — Adult practical minimum around 120 x 60 x 120 cm, with additional height preferred for this arboreal species
A thermometerbecause Temperature — cool 26-27 °C
A hygrometerbecause Humidity — Humidity Management Humidity needs to stay between 65 to 100 percent.
UVB (T5), stated as requiredbecause UVB — Zoomed T5 5.0 ReptiSun bulbs running the full length of the enclosure provide appropriate UV exposure.
Not stated: The heat sourcethis sheet names only the cool side: « cool 26-27 °C »

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.

This sheet states 6 of 7 of the fields this product runs on. What is missing turns something off: 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.
