Buffered coco peat is a type of coco peat that has been pre-treated or “buffered” to remove excess sodium ions and balance out the naturally occurring potassium. Coir pith, which is the fibrous material that surrounds the coconut shell, is a common source of coco peat. In its natural state, coir pith contains high levels of sodium ions that can cause issues for plants grown in the coco peat, such as calcium and magnesium deficiency.

To buffer coco peat, it is soaked in a solution high in calcium for a specific duration of time, which displaces the sodium ions and balances out the naturally occurring potassium. After the soaking period, the coco peat is washed thoroughly with water to remove any excess sodium ions, leaving only the calcium in the coco peat. This buffering process ensures that the coco peat is free from unwanted elements and ideal for use as a growing medium, with optimal levels of calcium and magnesium and no issues related to sodium toxicity. Buffered coco peat is widely used as a growing medium in hydroponic and traditional soil-based agriculture, and is valued for its ability to promote healthy root growth and high crop yields.
