Diatomite (Diatomaceous Earth or "DE") is a sedimentary rock primarily composed of the fossilized remains of unicellular fresh water plants known as Diatoms. Over the millennia the diatoms have been compressed to create one of the most effective growing mediums available. Diatomite consists of approximately 90% silicon dioxide, with the remainder of its contents being elemental minerals, which are essential for plant growth. All of these unique factors make Diatomite the definitive horticultural grade growing medium.
High Silica Content - Silica is essential for healthy plants and roots. Because diatomite is 90% silica, your plants will receive a slow release of silica resulting in healthier more robust plants.
Absorbency & Porosity - Diatomite is naturally very porous, and can hold 150% of its weight in water. The Silica Content, natural Absorbency, and Porous qualities result in a slow release of water and nutrients to your plants, contributing to higher yields and less watering.
Capillary Action & Lateral Movement - The porosity of the Diatomite contributes to its ability to draw water, while moving water and nutrients laterally throughout the medium, making Diatomite ideal for hydroponics.
