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 premium horticultural grade medium for all growing applications.

All Diatomite is not created equal. You may be familiar with diatomaceous earth that is used in filters and as an insect and slug repellant. These types of products are not suitable for horticulture because the diatoms are of salt-water origin, leaving them with a high salinity level that is not suitable for plants.

Our diatomite is Maidenwell(TM) Diatomite and comes from an Australian mine that has a fresh water origin. Maidenwell(TM) is a natural, non-toxic, with minimal contaminants and salts that make most other sources unsuitable for horticulture.

WHY USE DIATOMITE?

Diatomite is High in Silica, Absorbent,Porous, Long Lasting, Environmentally Friendly, pH Neutral, Sterilized, Natural and Reusable, all factors necessary for healthy plants while still being cost effective for the grower.

WHAT ARE THE BENEFITS OF USING DIATIMITE?

Silica is essential for healthy plants and roots. While Diatomite is approximately 85% insoluble Silica, it contains a small but significant portion that is SOLUBLE SILICA. Silica is essential for healthy plant and roots. Your plants will receive from Diatomite a slow release of silica resulting in healthier, more robust plants. Plants available silica has been shown in studies to stimulate SYSTEMIC ACQUIRED RESISTANCE (SAR) in plants, which increases their resistance to disease.

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.

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!

Diatomite is multifaceted and varies in size. Because each rock is unique in shape it does not compact while in the pot. This leaves pockets, allowing air to penetrate and circulate to the root zone.
