Calcined clay is a high-fired inorganic substrate that holds its particle structure and allows for excellent longterm drainage, regardless of how long or frequently you mist. Because it is a fired clay, it never breaks down or loses its structure.
It takes approx. 1 Litre of calcined clay to fill the vivarium trough. It takes an additional 1 litre to apply a 1/2" drainage layer beneath an organic substrate.
