Castle Mountain Zeolite

The hardness of CMZ is important in its physical benefits for soil and/or potting mixes. The blocky shapes of granular CMZ allow a high level of air filled proposity (AFP), thus providing the air spaces necessary to keep roots aerated. This is important because plant roots are aerobic ie they need air to live.

The highly porous structure of CMZ allows for the binding and retention of heat. This is important for the growing of plants in the cooler months particularly when solar radiation is trapped. 

In the summer regular watering of plants provides release of moisture from the CMZ by evaporative cooling.

Zeolites are very stable solids that resist all kinds of environmental conditions. They are not soluable, unreactive, and do not need replenishment year on year. They have no harmful environmental impacts and are frequently used in remediation of soils.
