Sol Soils Calcined Clay 2 quart


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.

At Sol Soils, we are passionate about the beauty of plants and the natural world. But passion doesn't change the world without action. Through our partnership with global non-profit One Tree Planted, we donate a portion of every bag sold to plant a tree in the world's most deforested areas. With each purchase of a Sol Soils product, you are directly contributing to the restoration of our planet's most beautiful and important ecosystems.
