Excessive water retention and poor aeration create anaerobic conditions that lead to root rot and stunted growth. The Char Coir 70/30 Coco + Perlite blend solves these problems with a precision-engineered ratio that delivers superior drainage while maintaining optimal moisture levels—creating the ideal environment for explosive root development and maximum yields.
Trusted by commercial and home growers worldwide, this premium 70/30 blend combines Char Coir's industry-leading coco coir with perlite to provide the perfect balance of aeration, drainage, and water retention. The substrate is naturally buffered to stabilize pH between 5.5-6.5 and enhance nutrient uptake, while triple washing ensures a very low EC level for a clean, pathogen-free environment free from excess salts.
The 70/30 ratio provides more drainage and aeration than standard blends like the 50/50 Cloud Coir, making it ideal for growers who prefer frequent fertigation or automated irrigation systems. This increased perlite content prevents compaction, ensures consistent oxygen flow to the root zone, and accelerates dry-down cycles for faster growth rates and enhanced nutrient uptake efficiency.
Each 50-liter bag (1.75 cubic feet) provides ample volume for filling grow pots, raised beds, or hydroponic systems with professional-grade substrate. Ideal for indoor or outdoor applications including vegetables, flowers, herbs, and high-performance growing systems—the 70/30 blend is a preferred choice in the coco coir market for growers who demand maximum aeration and precise moisture control.

The 70/30 blend contains more perlite (30% vs 50% coco), providing superior drainage and aeration compared to the 50/50 Cloud Coir. This makes the 70/30 ideal for automated irrigation systems, frequent fertigation schedules, or growers who prefer faster dry-down cycles. Choose 50/50 for more water retention or 70/30 for maximum drainage and oxygen availability.
No, the 70/30 blend arrives ready to use straight from the bag. It's been triple-washed to ensure very low EC levels and is naturally buffered to maintain pH between 5.5-6.5. Simply open the bag, fill your containers, and begin your feeding program immediately.
The 70/30 blend requires more frequent watering than higher coco ratios due to its enhanced drainage. Most growers water 1-3 times daily depending on plant size, container volume, and environmental conditions. Automated drip systems work exceptionally well with this blend, allowing multiple daily irrigations for optimal growth rates.
Yes, the 70/30 blend works for all plant types but excels with crops that prefer well-drained conditions or benefit from frequent fertigation. It's particularly popular for high-performance growing systems, commercial operations with automated irrigation, and growers seeking maximum oxygen availability for explosive growth rates.
A 50-liter bag (1.75 cu ft) will fill approximately ten 5-gallon pots, twenty-five 2-gallon pots, or fifty 1-gallon pots. Actual coverage depends on pot dimensions and how firmly you pack the substrate.
Yes, you can add more perlite if you want even faster drainage, though most growers find the 70/30 ratio optimal for high-performance growing. Adding perlite beyond 40-50% total volume may reduce water retention too much and require very frequent irrigation to prevent plant stress.
Any complete hydroponic or coco-specific nutrient line works excellently with the 70/30 blend. The enhanced drainage makes it ideal for precision feeding schedules with frequent, lower-volume irrigations. Many commercial growers prefer running 2-4 daily feedings at moderate EC levels rather than single daily irrigations at higher concentrations. For beginners, understanding how to optimize this process is crucial, and our guide to achieving the best autoflower yield setup offers great tips on feeding strategies.
Perlite doesn't retain nutrients like coco coir does, so the 70/30 blend has slightly lower nutrient holding capacity than pure coco. This makes consistent feeding schedules even more important—but the tradeoff is superior oxygenation that often results in faster growth rates and enhanced nutrient uptake efficiency that more than compensates for reduced retention.
