Poor drainage and compacted substrates lead to oxygen deprivation, root rot, and stunted growth. Char Coir Cloud Coir solves these problems with a precision-engineered 50/50 blend of RHP-certified coco coir and perlite that delivers superior water retention with exceptional aeration—creating the ideal environment for explosive root development and vigorous plant growth.
Trusted by commercial and home growers worldwide, Cloud Coir is a premium medium from the Char Coir lineup that combines high-pith coco coir with perlite to minimize compaction while maintaining optimal moisture levels. 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 Cloud Coir to retain and release nutrients efficiently, supporting robust root development and providing plants 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 various containers, from raised beds to specialized Bio Pots. Ideal for indoor or outdoor applications including plants, vegetables, flowers, herbs, and hydroponic setups—Cloud Coir is the preferred choice for growers who demand the highest quality substrate available.
Perlite integration prevents compaction and ensures consistent oxygen flow to roots for healthier plants.
Perfect for plants, vegetables, flowers, herbs, and hydroponic systems indoors or outdoors.
50 liters (1.75 cu ft) per bag provides ample substrate for pots, raised beds, and systems.
Completely biodegradable formula supports eco-friendly growing without compromising performance.

The 50/50 blend combines the superior water retention of coco coir with perlite's exceptional drainage and aeration properties. This creates an optimal growing environment that prevents both waterlogging and drying out, while ensuring consistent oxygen flow to the root zone for healthier, more vigorous growth.
No, Cloud Coir is 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, Cloud Coir is excellent for seedlings and clones. The balanced aeration prevents damping off while maintaining adequate moisture for delicate root systems. For starting seeds directly, many growers also use specialized coco coins before transplanting into a larger medium. Start with a gentle feeding program since the substrate is nutrient-free and gradually increase as plants mature.
Cloud Coir provides superior drainage and prevents compaction compared to straight coco coir, thanks to the perlite integration. This makes it more forgiving for growers who tend to overwater and ensures better oxygen availability. For growers who prefer a higher water retention rate, the Char Coir 70/30 blend is also an excellent option.
Yes, Cloud Coir is 100% biodegradable and sustainably sourced, making it ideal for organic growing operations. It's free from synthetic additives and works excellently with organic nutrient programs, though you'll need to provide all nutrients as the substrate contains none. Our guide to the best autoflower setup can help you plan your feeding schedule and environment.
Store Cloud Coir 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.
While technically possible, reusing Cloud Coir risks introducing pathogens, nutrient imbalances, and degraded perlite that compromises drainage. For optimal results and consistent yields, we recommend using fresh substrate for each crop cycle to ensure your plants have the cleanest, most effective growing environment.
