CocoCore 50L 70/30 is a pre-blended, loose-fill soilless growing medium combining 70% buffered coconut coir with 30% perlite. Designed for commercial cannabis and hemp cultivation, it provides a balance of moisture retention, drainage, and root-zone aeration for controlled fertigation programs. The coco coir retains water and nutrients, while the perlite increases macro-porosity, allowing excess water to drain efficiently and helping maintain oxygen availability around the roots during frequent irrigation. The substrate arrives pre-buffered with calcium and has a low starting EC, helping growers establish their own nutrient-feeding programs without first correcting a high residual salt load. Supplied ready to use in 50-liter bags, it requires no rehydration under normal storage conditions.
• Product Type: Pre-blended, loose-fill soilless growing medium
• Brand: CocoCore
• Bag Volume: 50 L (approximately 1.77 cu. ft.)
• Blend Ratio: 70% buffered coco coir / 30% perlite
• Substrate Composition: Coconut coir pith and fiber blended with perlite
• pH Range: 5.8–6.5
• Starting EC: ≤ 0.5 mS/cm
• Form: Loose-fill substrate, ready to use
• Buffering: Pre-buffered with calcium
• Pathogen Status: Sterile and weed-seed free
• Primary Applications: Commercial cannabis and hemp cultivation
• Suitable Growing Systems: Drip-to-waste, Dutch bucket, and hand-watered container systems
• Irrigation Compatibility: Automated drip irrigation and high-frequency fertigation
• Water Retention: Coco coir retains moisture between irrigation events
• Root-Zone Aeration: Perlite increases air-filled porosity and drainage
• Drainage Performance: Supports consistent drainage and reliable drain-fraction measurements
• Container Compatibility: 3-, 5-, 7-, and 10-gallon fabric or rigid pots
• Preparation: Ready to use directly from the bag; no rehydration is normally required
• Nutrient Management: Pre-buffering improves the initial calcium balance, but calcium and magnesium supplementation should continue through the feeding program
• Recommended Drain Fraction: Approximately 10–25% for applicable commercial drain-to-waste programs, adjusted to crop and system requirements
Key Advantage: CocoCore 50L 70/30 combines the water-retention characteristics of buffered coco coir with the increased drainage and aeration provided by 30% perlite. Its consistent, ready-to-use blend is particularly suited to automated, high-frequency drip fertigation, helping commercial growers maintain root-zone oxygenation and predictable drainage without manually mixing separate substrates.
