Zeolite

Zeolite is a natural volcanic mineral known for its ability to trap and slowly release nutrients while increasing drainage. Zeolite helps retain nutrients and water while improving root oxygenation. Sourced in the USA and perfect for customizing your substrate or boosting drainage in your mix. In PON, zeolite helps reduce fertilizer loss and supports strong, consistent root growth — especially useful for tropical plants and semi-hydroponic setups.
