Professor’s Coco Perlite 70/30 Blend is a premium ready-to-use growing medium containing 70% Coco Coir and 30% Perlite, providing an ideal balance between moisture retention, drainage and root-zone aeration.

Washed, pre-buffered and RHP Certified, this coco perlite mix is manufactured to high quality standards to provide growers with a clean, consistent and reliable substrate for hydroponics, indoor growing and container plants.

With a stabilised pH range of 5.5–6.5 and a very low EC of less than 0.5, Professor’s Coco Perlite provides an excellent foundation for precise nutrient management and healthy root development.

Why Choose a 70/30 Coco Perlite Blend?

The combination of 70% coco coir and 30% perlite gives growers the moisture-holding capacity of coco with the increased drainage and aeration provided by perlite.

Coco coir retains moisture and nutrients around the root zone, while perlite creates small air spaces throughout the substrate. These air pockets allow water and oxygen to move more freely around the roots while helping prevent the growing medium from becoming overly compacted.

The result is a well-aerated root environment that gives growers greater control over irrigation and nutrient delivery.

Better Drainage Without Sacrificing Moisture

Perlite is widely used with coco coir because it improves drainage while allowing the growing medium to retain the moisture plants need.

The 30% perlite content creates additional pore space throughout the substrate, allowing excess water to drain while maintaining an effective balance between moisture and air.

This makes Professor’s Coco Perlite particularly suitable for growers who want greater control over irrigation and want to reduce the risk of waterlogged root zones.

Improved Root-Zone Aeration

Healthy roots require access to oxygen. Perlite particles create tiny air channels throughout the coco substrate, helping oxygen and moisture move freely around the root system.

Because perlite is lightweight, rigid and naturally porous, it also helps resist compaction. This allows roots to penetrate deeper into the growing medium and provides an oxygen-rich environment for vigorous root development.

Washed and Pre-Buffered Coco

Professor’s Coco Perlite is supplied washed and pre-buffered, helping provide a consistent growing medium straight from the bag.

Its very low EC of less than 0.5 gives growers greater control over nutrient application, while the stabilised 5.5–6.5 pH range supports efficient nutrient availability within the root zone.

RHP Certified Growing Medium

Professor’s Coco Perlite carries RHP Certification, providing additional assurance of the quality and consistency of the growing medium.

The certification helps ensure the substrate has remained clean throughout production and meets strict quality requirements for professional horticultural use.
