Frequently Asked Questions (FAQs)

1. How do you measure the temperature of a terrarium?

To measure the temperature of a terrarium accurately, analog thermometers on the walls are only suitable for measuring ambient or air temperature. For basking temperature, it is recommended to use a temperature gun or a digital thermometer/thermostat probe.

2. Where do you put a thermostat in a terrarium?

For optimal placement of a thermostat in a terrarium, it is advisable to position the probe in the middle of the vivarium. Set the thermostat to the middle of the desired temperature range. It is important to verify the temperatures in other areas of the vivarium using a reliable digital thermometer.

3. Where do you put the humidity gauge in a terrarium?

To get accurate humidity readings in a terrarium, avoid placing the hygrometer near water sources or heat lamps, as this can affect the measurements. It is recommended to place the hygrometer in an area with minimal influences, where the humidity levels are least affected.

4. How much heat should a terrarium have?

The amount of heat required for a terrarium depends on the type of animals and their natural habitat. Nocturnal tropical forest animals prefer temperatures between 23 and 30 °C during the night, while night-active desert animals prefer temperatures from 15 to 22 °C. It is important to provide the appropriate heat levels based on the specific needs of the terrarium inhabitants.

5. What is the ideal temperature for a closed terrarium?

In a closed terrarium, it is important to avoid direct sunlight as it can cause excessive heat and condensation. The average room temperature of around 19-21°C is suitable for a closed terrarium. Proper ventilation is crucial to prevent excess moisture build-up.

6. How do I keep my terrarium warm at night?

To keep a terrarium warm at night, you can use ceramic heat lamps or heating mats that provide heat without visible light. This is particularly important for nocturnal animals that require warmth during the dark phase.

7. How do I know if my terrarium is too humid?

If you notice droplets forming on the glass of your terrarium, it is an indication that there is excessive moisture inside. This suggests that the terrarium may be too humid, and adjustments should be made to regulate the humidity levels.

8. How humid should a closed terrarium be?

The ideal humidity level for a closed terrarium will depend on the specific needs of the plants or animals inside. However, most high humidity terrarium plants require a relative humidity above 50%. It is recommended to monitor and adjust the humidity levels accordingly to create a suitable environment for the terrarium inhabitants.
