Zoo Med Eco Earth Loose Coconut Fiber Reptile Substrate is an eco-friendly product made from the husks of coconuts. It’s a renewable resource that can be safely composted or recycled into potted plants or gardens. This substrate is ideal for naturalistic terrarium-type setups incorporating reptiles， amphibians or invertebrates. Use it damp for tropical species， as it naturally absorbs and breaks down odor and waste products. Add Eco Earth loose coconut fiber substrate on top of Zoo Med HydroBalls to create an ideal drainage layer for optimum plant growth and humidity in naturalistic terrariums.
