Professor’s Nutrients - Coco-Perlite Blend (70/30) – Premium High-Aeration Substrate (50L)

Professor’s Nutrients - Coco-Perlite Blend (70/30) – Premium High-Aeration Substrate (50L)

Maximising root zone oxygenation is the fastest way to accelerate plant growth, and Professor’s Nutrients Coco-Perlite Blend is engineered to deliver exactly that. This professional-grade substrate features a scientifically optimised mix of 70% premium RHP-certified Coco Coir and 30% horticultural-grade Perlite. By blending these two powerhouse media, this substrate combines the exceptional water retention and nutrient buffering of pure coco with the unmatched drainage capabilities of perlite. This lightweight, airy mix effectively eliminates the risk of over-watering and compaction, creating an ideal, oxygen-rich rhizosphere where roots can expand rapidly and absorb nutrients at peak efficiency.

Best For: High-frequency automated drip irrigation systems, run-to-waste hydroponics, hand-watered container gardens, and heavy-feeding crops that demand maximum root aeration.

Key Features

• Optimised 70/30 Commercial Ratio: The industry-standard blend provides the perfect balance between moisture retention and rapid drainage, ensuring plants stay hydrated without ever becoming waterlogged.
• Advanced Air-Tunnel Aeration: The inclusion of 30% perlite creates microscopic air pockets throughout the substrate. This prevents the medium from compacting over time, allowing fresh oxygen and nutrient solutions to flow freely to the root tips.
• Anti-Overwatering Protection: Excellent drainage capabilities mean excess water moves through the pot effortlessly, significantly reducing the risk of root rot (Pythium), fungus gnat infestations, and anaerobic root zones.
• RHP-Certified Coco Base: Utilises the same world-class, premium coco found across the Professor's range—thoroughly washed and pre-buffered to ensure an ultra-low background EC and complete freedom from pathogens, weeds, or pests.
• Stable Chemical Baseline: Naturally buffered to maintain a stable pH range, ensuring that your hydroponic nutrient solution remains fully bio-available from the moment it hits the medium.
• Ready-to-Use Convenience: Pre-blended and loose-filled into 50L bags, eliminating the labor-intensive task of sourcing, measuring, and mixing raw ingredients yourself.

Feeding & Irrigation Tips

• High-Frequency Feeding: Due to the increased drainage provided by the 30% perlite content, this mix dries back faster than pure coco. It is perfectly suited for multi-feeding schedules (multiple smaller irrigations per day), which drives explosive vegetative growth and heavier yields.
• Targeted Runoff: When liquid-feeding, always aim for a consistent 10–20% runoff. This ensures that old mineral salts are completely flushed from the perlite air pockets, replacing them with a fresh, highly-oxygenated nutrient charge.
• Pot Optimization: For the ultimate high-aeration setup, use this blend in fabric aeration pots. The combination of fabric air-pruning and the 70/30 mix will result in a massive, dense root ball free of root-circling.
• Nutrient Selection: Because the base is 70% coco, always use a high-quality, 2-part **Coco Specific Nutrient** to ensure your plants receive adequate Calcium and Magnesium levels throughout their life cycle.

Ideal For (Uses)

• Automated Drip Hydroponics: The absolute benchmark medium for automated run-to-waste systems where precise, frequent watering cycles are managed via timers.
• Fast-Flipping Commercial Cycles: Ideal for commercial facilities looking to shorten vegetative turnaround times through accelerated root development.
• Soil Lightening: Can be used to amend heavy, dense organic potting soils to improve their overall structure, drainage, and oxygen capacity.
