Calcined Clay (2–9mm) Montmorillonite

Calcined Clay (2–9mm) Montmorillonite

Aeration • Drainage • Moisture Regulation 

This horticultural-grade calcined clay is made from kaolin-rich montmorillonite, heat-treated to create a porous, mineral-rich substrate that enhances soil performance. With excellent aeration and moisture balance, it’s ideal for bonsai, houseplants, succulents, and cacti—or any mix that benefits from structure and long-term drainage.

The 2–9mm (1/8”–3/8”) particle size blends easily into soil or can be applied as a top mulch to reduce evaporation and prevent compaction.
