Frequently Asked Questions
What humidity does my terrarium need?
It depends heavily on the species and its natural habitat – desert dwellers often need just 30-40%, while tropical species need 70-90%.
How do I increase humidity in a terrarium?
Regular misting, a water dish, misting systems or foggers, and moisture-retaining substrates all help.
How do I lower humidity that's too high in a terrarium?
Better ventilation, misting less often, and a drier substrate all help bring humidity down.
Why is the right humidity so important?
Conditions that are too dry or too humid can cause shedding problems, respiratory illness, or fungal infections in reptiles and amphibians.
