The ProRep Bio Life Drainage medium is used in the base of bio-active terrariums; it creates a reservoir of water which moistens the substrate from below and helps to create a natural moisture gradient.
ProRep Bio Life Drainage Medium is produced by firing ash at a high temperature. As it fires the air bubbles in the material expand to form a honeycomb of interconnected chambers and create an inert, hard and lightweight material that will hold moisture and provides a large surface area for the growth of beneficial bacteria. The large surface area within each ball provides the ideal habitat for beneficial bacteria which will neutralise potentially harmful waste products formed within the ecosystem.
