Cocopeat, also known as coir pith, is a byproduct of coconut husk processing. It is widely used as a growing medium in horticulture because of its ability to retain water and nutrients. Cocopeat is available in two forms: Low EC (electrical conductivity) and High EC. Many also ask about the difference between the two. in this article we show some of the differences between the two:
- Materials: Low EC cocopeat is made from mature coconut husks, while high EC cocopeat is made from younger, less mature husks. The difference in maturity affects the composition of the cocopeat, with the older husks containing less salt and other impurities.
- Processing methods: Low EC cocopeat undergoes a longer washing and buffering process, which removes more of the impurities and salts. High EC cocopeat, on the other hand, undergoes a shorter washing process, resulting in higher levels of salts and other impurities.
- Electrical conductivity: The electrical conductivity of a growing medium is a measure of its ability to conduct an electric current. Low EC cocopeat has a lower electrical conductivity than high EC cocopeat, which means it contains fewer salts and other minerals. High EC cocopeat, on the other hand, has a higher electrical conductivity, indicating higher salt content.
- Nutrient availability: The salt content in high EC cocopeat can affect the availability of nutrients to plants. High levels of salts can create an imbalance of nutrients and prevent plants from absorbing them properly. Low EC cocopeat, on the other hand, has fewer salts and impurities, making it easier for plants to absorb nutrients.
- Water holding capacity: Both low EC and high EC cocopeat have excellent water holding capacity, which means they can retain water and nutrients for extended periods. However, high EC cocopeat can become compacted over time due to the high salt content, reducing its water holding capacity.
- pH levels: The pH of cocopeat can vary depending on the maturity of the coconut husks used and the processing methods. Low EC cocopeat typically has a more neutral pH, while high EC cocopeat may have a more acidic pH due to the higher salt content.
- Uses: Low EC cocopeat is suitable for use in hydroponic systems, as it contains fewer salts and impurities that can harm plants. It is also ideal for growing sensitive crops that require low levels of nutrients, such as lettuce and herbs. High EC cocopeat is suitable for use in less sensitive crops, such as tomatoes and peppers, that can tolerate higher levels of nutrients.
- Cost: Low EC cocopeat is generally more expensive than high EC cocopeat due to the longer washing and buffering process required to remove more impurities and salts.
In summary, Low EC cocopeat is preferred for hydroponic systems, sensitive crops, and those requiring low nutrient levels. It has a higher price point but offers better quality and more consistent performance. High EC cocopeat is a suitable option for less sensitive crops, such as tomatoes and peppers, and is typically less expensive. However, it may have higher salt levels, affecting nutrient availability and water holding capacity.
