Char Coir - Professional Grade Coco Coir Growing Medium

RHP certification is a Dutch quality mark that ensures the coco coir meets strict standards for purity, physical structure, and chemical composition. It guarantees that the medium is free from pathogens and weeds, providing a consistent, high-quality environment for your plants.

Yes, Char Coir is buffered to ensure the medium does not lock out essential nutrients. This process stabilizes the cation exchange capacity, allowing your plants to access nutrients more effectively from the start.

A low EC (less than 0.2 dS/m) indicates that the coco coir has been thoroughly washed to remove excess salts. This gives you full control over your nutrient solution, as you won't have to worry about salt buildup affecting your plants' uptake.

While Char Coir has excellent drainage on its own, adding perlite is a great way to customize the aeration and drying speed. If you are growing in a high-humidity environment or prefer a faster dry-back time, mixing in perlite is a standard and effective practice.

By drying the coir more thoroughly than standard products, Char Coir prevents the growth of harmful bacteria and fungi during transit. This process also reduces the overall weight of the bag, making it easier to handle without sacrificing the integrity of the medium.
