In simple words, coco coir is a natural fiber product that is obtained from the husks of ripe and unripe coconuts. It has taken over the gardening world because of its numerous benefits. Some of which include high water absorbency, increased aeration, and better drainage. It is also an excellent choice for seed starting, encouraging plant growth, and supporting root structures in hydroponic systems.
Coco pith - coco peat is spongy and looks like loose tea leaves. It performs the function of water retention and can absorb high amounts of water. Apart from its sponginess, its wood-like nature means that it breaks down slowly. However, it doesn't have much capacity to hold air because of its small and fine particles.
Moreover, a well-aged coco pith holds good amounts of sodium and potassium. Which is why, when you're out buying coco pith, make sure that it has been aged for at least four months. Since aged pith already has enough sodium and potassium, the fertilizer fulfills the need for calcium.
The majority of the world’s coconut fiber comes from Sri Lanka or India.
