High EC (electrical conductivity) coconut husk chips are a type of horticultural substrate made from the fibrous material found between the hard outer shell and the flesh of a coconut. It is a renewable and organic resource that is commonly used as a growing medium for plants.

The coconut husk chips are soaked in water to remove excess salts and other impurities that could be harmful to plants. This process helps to reduce the electrical conductivity (EC) of the substrate, making it more suitable for plant growth. Low EC coconut husk chips have a lower salt content than regular coconut husk chips, which can be beneficial for plants that are sensitive to high levels of salt.

The low EC coconut husk chips are then compressed into block shapes for ease of handling and transportation. The blocks are typically wrapped in plastic or other materials to prevent them from drying out and to protect them from damage during transport.

To use the low EC coconut husk chips blocks, they are soaked in water to rehydrate them and allow them to expand. The expanded blocks provide a loose, aerated medium that is ideal for plant growth. The low EC coconut husk chips blocks have excellent water retention and drainage properties, allowing plants to receive the right amount of moisture and air.
