Unwashed, washed and buffered coir
Unwashed coir often comes from young, unaged coir husk. The biological micro-activity in the husk is still present and the natural salts are retained in high concentrations because the husk was not washed out by natural precipitation or an artificial rinsing process.
Washed coir: Abundant rinsing with (rain) water removes salts from the material. This process provides a more stable chemical composition and makes this coir raw material more suitable for a wider range of applications.
Buffered coir undergoes an additional process in which sodium and potassium ions are replaced by calcium ions. This treatment is mainly done at our production site in Bree and results in a coco peat that can be used immediately for sensitive crops.
