Know before you buy
RHP certification is a rigorous quality standard that ensures the coco coir is free of pathogens, weeds, and harmful substances. It guarantees consistency in the product's physical and chemical properties, giving you confidence that every bag performs the same.
No, you do not need to rinse it. This product is triple-washed to remove excess salts and is ready to use straight out of the bag.
Yes, this product is buffered, which means it has been treated to balance the cation exchange capacity. This prevents the medium from locking up essential nutrients like calcium and magnesium, ensuring your plants have consistent access to the fertilizer you provide.
This coco coir is excellent for both applications. Its high moisture retention and low EC make it a versatile, high-performance substrate for hydroponic systems as well as a great amendment for traditional potting mixes.
This pH range is considered the 'sweet spot' for most plants, as it allows for optimal nutrient uptake. Because the coir is pre-stabilized within this range, you won't need to worry about significant pH fluctuations affecting your plant's health.
