SoilRox™ Soil Amendment (Enhancer • NF)

Pumice stones sized between 3/8 and 1/8 inches (average). Contains no fines (NF). Enhances aeration as well as water and nutrient retention properties. Used in specially-crafted soil and grow media blends where elemental tilth and friability is inherent, making the for need for pumice fines to improve the soil structure unnecessary. Though lightweight, SoilRox is somewhat heavier than perlite and vermiculite, providing more substance and anchoring weight for growing top-heavy plants in pots. SoilRox does not tend to work its way to the surface over time like lighter amendments, and the irregular, grippy edges of the stone also work to bind it into the soil matrix.

Typical Applications: Blended in specialized soil (no native soil) formulations used for container-grown plants, grow boxes, greenhouse beds, seed pots, and garden plots. 

Typical Applications 2: Used in specialized media blends (or used straight up) to grow succulents, bromeliads, cacti. Also used by bonzai growers.

About Pumice: Pumice is literally a foamed stone, formed in the awesome heat and violence of a volcano. Pumice stones—including the tiny fines—are riven with nooks and crannies and pockets that hold moisture and nutrients in the root zone and make them available to the root systems over a longer period of time. As a soil amendment, pumice also provides elemental tilth—opening dense, heavy soils to enhance critical gas exchange in the root zone.
