Peat Moss vs Coco Coir: Which One Is Better?

You are a modern agricultural farmer looking for products that are fit for crops and provide high quality. You have heard of coco peat and peat moss products as the alternative organic soils that can replace the traditional soil. However, you are not sure which one suits your plants and how to use them. This article by EnvironSoil will compare peat moss vs coco coir and clarify some points so that you can make the best decision.

1. General overview about coco coir

Coir coir (also known as coco peat) is a product produced from coconut husks that can be used as an alternative to the soil for planting once tannins, lignin, EC, and pH are processed to a level suitable for plants.

Coco peat as shown above, contributes to plant growth and brings huge value to the living environment, particularly natural renewable energy sources, due to its safe and tested features.

2. The introduction about peat moss

Peat moss is found in deep swamps and contains mostly white moss (sphagnum moss). Peat moss is found in Russia, Finland, Ireland, Sweden, Germany, etc. in the form of light brown, loose fibers. They are harvested, dried, and become a clean source of carbon-rich materials to replace agricultural land.

Although officials generally disagree that peat moss is economically viable due to its poor capability of regenerating. According to a study from the University of Washington in the United States, peat moss lagoons require at least 25 years to regenerate and retain their original value. The high levels of carbon released during the decomposition of this substrate and other natural materials lead to an increase in the greenhouse effect. Furthermore, it has a negative impact on global warming.

3. The differences between coco coir and peat moss

ContentCoco coirPeat moss
PriceCheap,  easy to find and buyRelatively expensive and hard to find
pH balance level

Average from 5.2 to 6.5

Standard level for crop development.

From 3 to 4.5

Perfect level for growing plants

Water capacity

From 7 to 10 times for dry weight

Good drainage and not waterlogged

From 3 to 6 times for dry weight. 

Tend to be waterlogged

Water supply time

+ Fast

As coco peat has an absorbent sponge-like structure, they are capable of absorbing large amounts of water quickly

+ Usually slower than coco peat

Since peat moss does not have a sponge-like structure. But it has a ship-shaped structure like the leaves of white moss (sphagnum moss) to retain water. However, modern harvesting technology can endanger this structural foundation.

Expiry date

+ Approximately 5 years

Coco peat has a large amount of natural lignin (45%), which avoids the decomposition effect of fungi and bacteria.

+ From 6 months to 1 year

Depends on the area of formation and quality of the product.



Coir peat has the ability to ventilate and hold air even when containing a large amount of water without being waterlogged 


When water is applied to peat moss, the amount of air present in the product decreases. As a result, there is no supply to the roots.

Ability to maintain original form (Shrinkage)


Due to a large amount of lignin and fibrous structure. Coir peat does not shrink and retains its original shape


Peat moss shrinks from the sides of the bag and when supplied with water it is easy to drain away. And for longer trees, a large amount of peat moss is needed, so the cost also increases

Water retention

+ Long-lasting water retention

Although the coco peat breaks down into a sponge-like structure, it retains up to 78% of its water content

+ Quick drainage

Peat moss only has a low water holding capacity and therefore requires frequent watering.


+ Excellent

No need to add any other auxiliary products. Common coco peat has up to 96% off holes that allow water to flow through easily, thereby avoiding flooding at the same time

+ Mid-range

Need to add other by-products such as perlite, rice husk, etc. to get more porosity

If it is too dry, will it be calloused?

+ No

Due to the sponge-like structure, it will not affect the ability to quickly absorb water

+ Yes

Peat moss is only used for a short time. and if it is too dry, the surface will shrink and lock the hole to absorb water and air, so it needs a high cost to renovate.

Ion exchange capacity (+)

+ High

Coir peat has a high rate of CEC because the amount of ions is allocated to the molecular structure and is not filtered away. Hence, it can be kept and released with the right amount for the crop

+ Low

Peat moss often has a poor CEC rate if not supplemented with additional products such as perlite to avoid nutrient and ion leaching (+).

Each product type has its own distinct advantages. Hence, you need to be aware of all the features of each product to choose the most suitable one for your plants. Due to the impact of climate change and human overexploitation, the amount of peat moss in marshes is decreasing day by day. As a result, coir peat is a superior option, contributing to economic growth, enhancing productivity, and being environmentally friendly, all of which contribute to higher living standards.
