Understanding Buffered Coco Coir.

What is coco coir buffering? And why is it important? 

What is Coco Coir Anyway?

Coco peat, also known as coco coir, is a natural fiber extracted from the husk of coconuts. It is widely recognized for its excellent water retention capabilities, aeration properties, cation exchange and sustainability. Coco peat is a byproduct of the coconut industry, making it an sustainable choice for gardening and commercial growers.

What is Buffering?

Buffered coco coir refers to coconut coir that has undergone a buffering process to adjust its pH level and remove excess salts. 

Buffering Process

Buffering coco coir involves adjusting its pH and reducing the levels of salts present in the material. Here’s how the buffering process typically works:

1. Rinsing: Coco coir is initially rinsed with fresh water to remove any initial debris, dust, and excess salts that may be present on the surface.

2. Buffering Agents: The coir is then treated with buffering agents such as calcium carbonate (lime) or potassium carbonate. These agents help to neutralize the naturally high pH of raw coco coir and stabilize it within the desired range, typically around pH 5.5 to 6.5.

3. Soaking: The coir is often soaked or washed thoroughly with the buffering solution to ensure even distribution of the agents throughout the material.

4. Rinsing Again: After buffering, the coco coir is rinsed again with water to remove any excess buffering agents and salts that may have been displaced.

5. Drying: Finally, the buffered coco coir is dried to an appropriate moisture level suitable for packaging and use.

Why Buffering is Essential

The buffering process is crucial because raw coco coir can initially have a high pH and contain salts, which can be harmful to plants if not properly addressed. Buffered coco coir provides a stable and balanced growing medium that supports healthy plant growth without causing nutrient imbalances or toxicity issues. 


High quality buffered coco peat is a versatile, sustainable growing substrate that stands out in cannabis cultivation. Though often overlooked, the buffering process plays a crucial role in creating an optimal environment for plant roots. By understanding the significance of buffering coco peat and incorporating it into cultivation practices, professional growers can harness the full potential of this natural and renewable substrate. Pure Coco has gained significant traction in the cannabis industry in recent years due to the consistent high quality and cannabis specific design.

Don't just grow. Dominate.
