Hydrolite is the product name for Botanicare’s exclusive silica based mineral rock also known as zeolite. Hydrolite is a natural mineral that is mined in the US and selected for its ideal properties and high level of silica (>70%).
Hydrolite has a unique crystalline structure that makes it completely porous, yet extremely structurally rigid which creates good drainage and water holding capacity. The most significant aspect of zeolite is the elevated cation exchange capacity (CEC) that is higher than any known growing media. A high CEC means that the media can hold “reserves” of plant nutrients until needed for uptake by plant roots.
