This is pure Sphagnum Peat Moss, with no additives. Great as a substrate for forest dwelling reptiles or mixed 50:50 with vermiculite and used as an egg laying substrate. It has superior moisture retaining qualities compared to other Reptile, Amphibian, Roach, Tarantula, and Exotic Pet beddings. It can also be used for potting plants, soil mixes, and gardening. Reptiles also love to dig in it and make themselves at home!
