ProRep Hemp Bedding ProRep Hemp Bedding – A soft, fibrous substrate that is suitable for many species of snakes and tortoises as well as for small mammals. It is made from the dried chopped stem of the Hemp plant to form a highly absorbent, dust free and odourless material. Being completely biodegradable it is safe if eaten. Directions – Spread the substrate evenly over the bottom of the enclosure to a depth of at least 1-2” (2.5-5cm). Spot-clean daily and completely replace every two or three weeks, or more frequently if it becomes heavily soiled or wet. If you are using an under-tank heatmat as your heat source do not use a thick layer of Hemp Bedding as this may cause the heatmat to overheat.
