Lucky Reptile moss comes in two varieties, sphagnum and dry moss. Dry vivarium moss is great for creating areas of high humidity within your reptile’s enclosure. Soaked in water it will become green and fresh and retain moisture to increase humidity. Sphagnum moss comes in a dried brick and is also great to create areas of high humidity within your reptile’s enclosure. The whole brick will give about 5 litres of moist mass. You can also break off a small chunk of the brick to soak in water and put into a small hide to aid your reptile when shedding.
