This loose and absorbent substrate is made from coconut husks and is preferred by users who favor a tropical theme to their terrarium or are trying to increase the humidity in their enclosure. Burrowers will love its density and be at work in no time tunneling through their thick new terrain. Eco Earth also helps to break down odors and debris. When it becomes too soiled the substrate can be repurposed for gardens or plants that need some TLC. Approved by frogs, turtles, snakes, lizards, and invertebrates!
