The Rainfall and Humidity Parameters: Leap's programmable Mister and Fogger address the two important parameters of Rainfall (4) and Humidity (5). Both amphibians and reptiles require rainfall and humidity; to drink, to maintain healthy lungs and skin, and for other important biological processes. Misting (rainfall) facilitates the inclusion of tropical plants in your Leap habitat to create beautiful and natural environments for your animal and provides drinking water for your animals in the most natural way. The Leap Mister and Fogger incorporate programable volume and timing functionality to tuner rainfall and humidity to the specific needs of your habitat and animals.
