From Sol Soils
Calcined Clay has become a popular soil amendment for all categories of indoor plants. Its purpose is to meter moisture in the adjacent soil to keep it from getting soggy or bone dry. Fired at super-high temps it clocks in at 74 porosity which drains & aerates much more effectively than sand.
