Inconsistent substrate quality and nutrient imbalances undermine crop performance and reduce yields. Char Coir Coco Coir delivers 100% RHP-certified, peat-free growing medium with superior water retention and aeration properties that create the optimal foundation for explosive root development and vigorous plant growth across all stages.
Trusted by commercial and home growers worldwide, this premium loose coco coir features a high-pith ratio that ensures excellent moisture management while preventing compaction. The substrate undergoes meticulous buffering with calcium and magnesium to stabilize pH and enhance nutrient uptake, while triple washing removes excess salts and ensures a low EC level for a clean, pathogen-free environment.
The naturally high cation exchange capacity allows Char Coir to retain and release nutrients efficiently, supporting robust root development and providing plants with consistent access to essential nutrients throughout every growth stage. Sustainably sourced from a single farm to ensure batch-to-batch consistency, this 100% biodegradable solution supports responsible growing practices while delivering professional-grade performance.
Each 50-liter bag (1.75 cubic feet) provides ample volume for filling pots, raised beds, or hydroponic systems with reliable, consistent substrate. Ideal for indoor or outdoor applications including plants, vegetables, flowers, herbs, and hydroponic setups—Char Coir is the preferred choice for growers who demand the highest quality coco coir available.

No, Char Coir arrives ready to use straight from the bag. It's already been triple-washed to remove excess salts and buffered with calcium and magnesium to stabilize pH. Simply open the bag, fill your containers, and begin your feeding program.
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, Char Coir works excellently when mixed with perlite, vermiculite, or other amendments to customize drainage and aeration. Many growers add 20-30% perlite for enhanced drainage, though for convenience, you can also use a pre-mixed option like our 70/30 Coco Perlite Blend.
This product is 100% pure coco coir, while the Cloud Coir is a pre-mixed 50/50 blend of coco coir and perlite. Use straight coco coir when you want maximum control over your substrate blend or prefer to customize perlite ratios yourself. Choose Cloud Coir for the convenience of a pre-balanced, ready-to-use blend.
Store in a cool, dry location away from direct sunlight. Keep the bag sealed or transfer unused substrate to an airtight container to prevent moisture absorption and contamination. Properly stored, it will maintain its quality indefinitely.
Since this coco coir is nutrient-free, it works with any complete hydroponic or coco-specific nutrient line. The high cation exchange capacity makes it ideal for precision feeding schedules. Start with manufacturer-recommended dosages and adjust based on plant response. For general guidance, our 8-step guide on how to grow offers a helpful overview of the entire process.
Yes, Char Coir is 100% biodegradable, sustainably sourced, and free from synthetic additives, making it ideal for organic operations. It works excellently with organic nutrient programs, and for a certified OMRI-listed option, you might also consider the Coirganic Coco.
While technically possible after proper cleaning and re-buffering, reusing coco coir risks introducing pathogens, salt buildup, and degraded substrate structure that compromises drainage and aeration. For optimal results and consistent yields, we recommend using fresh substrate for each crop cycle. Using fresh starter media like Coco Coins is a great way to ensure a clean start for new seedlings or clones.
