Galapagos Bamboo Humidifier is made from natural bamboo and designed to boost humidity levels in your terrarium. Fill with moist moss and the moisture will slowly be released to raise the humidity level. Humidity helps reptiles shed easily and is essential for amphibians to hydrate. Natural bamboo are likely to split over time if exposed to rapid changes in moisture levels. Avoid direct exposure to sun light and heat lamps. Also ideal for egg incubation, tarantula hides, and even planting live plants!
