Cypress Bedding is designed for tropical terrariums. Our twice-milled cypress resists mold and decay and is breeder-tested and recommended. Ideal for frogs, snakes, lizards, and other reptiles. Although cypress bedding is recommended for high-humidity habitats, it can also be used for desert or low-humidity. For a desert habitat, keep the substrate relatively dry. Fluker recommends using our thermometer and hygrometer in your terrarium to monitor your pet's enclosure.
