Green iguanas are tropical reptiles and need considerably more humidity than desert species. A practical target is generally around 70–80% relative humidity, with good ventilation and opportunities for surfaces to dry rather than remaining constantly waterlogged.
How do I raise iguana humidity?
Depending on the enclosure, humidity can be supported with misting, appropriate moisture-retaining materials, live reptile-safe plants, and a large clean water source. Large enclosures may require a dedicated misting or humidity system.
How do I measure humidity?
Use a reliable digital hygrometer rather than estimating by feel. Check different areas because humidity can vary throughout a large enclosure.
Can humidity be too high?
Yes. High humidity combined with stagnant air and continuously wet surfaces can create husbandry problems. Humidity and ventilation need to work together.
