Terrariums are interesting pet environments. They are built for reptiles
so it has to provide the necessary heat and humidity for reptilian pets to thrive. Unlike mammals or bird pets, reptiles get their heat for internal biological processes from external sources. In the wild, most reptiles would bask in the sun to get enough UVB and UVA rays to stay healthy.
In a terrarium setting, their owners have to provide it for them. Normally terrariums have overhead heating, and for most practical purposes this is enough. However, if you live in northern climates and it could get quite cold, overhead heating might not be sufficient. You might need to look for heating that comes from below called under tank heating.
If you live in an area that has really harsh winters, while your pet is getting adequately heated from above, the water and liquid at the bottom of the terrarium might get really cold because of the ambient low temperature. In essence, your pet is hot and cold. It's hot at the top and very cold at the bottom. This could be quite unhealthy.
