Cocopeat block, also known as coir peat block or coconut coir block, is a compressed block of coconut coir fiber that is commonly used as a soil amendment and growing medium in horticulture.

Cocopeat blocks are made from the fibrous material that is left over after the extraction of the long coir fibers from the outer husk of the coconut. The fibers are washed, dried, and compressed into blocks. When hydrated, the blocks expand to several times their original size, providing a lightweight and highly absorbent growing medium for plants.

Cocopeat blocks have several benefits when used as a soil amendment and growing medium. They are pH-neutral, which means they will not alter the pH balance of the soil. They also have excellent water-holding capacity and provide good aeration to plant roots. Cocopeat blocks are also a renewable and sustainable resource, making them an eco-friendly alternative to other growing media.

Cocopeat blocks are commonly used for hydroponic gardening, greenhouse growing, and in potted plants. They are also used for soil conditioning, seed starting, and as a potting mix. They can be mixed with other soil amendments such as perlite or vermiculite to create a custom soil mix for specific plant needs.
