What is coco coir?

Coco coir is simply the extracted husk fiber of a coconut. When used as a growing medium, coco coir is a suitable substitute for peat moss.

How Is Coco Coir Made?

Coco coir is made by soaking part of a coconut in water for a long period of time. The piece of the coconut that is used is the "husk" or the fibrous middle area. Following the soaking process the husk is dried or "cured" for 6-12 months. This dried husk is then processed, sliced into thin chips or ground into tiny pieces, before it is usable for agricultural purposes.

Pros of Coco Coir:

- Environmentally friendly / sustainable
- Durable and sometimes even reusable
- Allows for growing medium pH range of 5.5 - 6.5 pH
- Holds about 1,000x more air then soil per unit volume

Cons of Coco Coir:

- Can be an allergen
- Can have contaminants if not from reputable source
- Can be slightly too acidic for some types of plants outside the 5.5 - 6.5 pH range
- Can interfere with nitrogen update in plants

Crops Associated with Coco Coir:
Mushrooms are often associated with coco coir, more than other types of crops.
