Professor’s Nutrients Coco – Perlite Blend is a mix consisting of 70% Coco Coir and 30% Perlite.

Professor’s Coco/ Perlite blend carries the RHP Certification, ensuring it has remained pure and clean throughout the production process, meeting it’s high quality attributes. It is washed and prebuffered and maintains a pH range of 5.5 – 6.5.

Perlite is a common addition to Coco Coir, being highly favoured for its excellent drainage capabilities while simultaneously maintaining high moisture levels, alleviating the risks of over-watering.

The main advantage of a perlite blend is its ability to keep the grow medium aerated. Plants need oxygen to thrive and survive, and perlite particles create tiny air tunnels which allow moisture and oxygen to flow freely to plant roots.

This is important, as most of the oxygen a plant gets is through its roots. Perlites hardness, along with its very low density and internal pockets of air prevent compaction, allowing roots to penetrate deeply, improving the rate of growth, and providing an oxygen-rich environment for roots to grow.
