Coco coir and peat moss have very similar structures and can be used in the same way. Both can be used on their own as growing mediums, in hydroponics or as a soil amendment mixed with other components. Coco coir is considered to be more environmentally friendly than peat moss since it’s a renewable product.
Keep in mind that coco coir lacks nutrients and natural peat moss has a pH of 2 which means that they both should be fertilized properly.
Coco pith, or coco peat - Retains water extremely well — so for this reason you might not want to use just coco peat as it could swamp the roots of your plants.
Coco fibers - are stringy bundles that allow oxygen to easily penetrate a plant’s root system.
Coco chips - are small chunks of coir that combine the best properties of peat and fiber. Coco chips retain water well but also allow for air pockets.
How to use
Coco coir and peat moss are sold packed in bags or as dried bricks. When dried, all you have to do is add water and let it sit for a while. Then squeeze out excess water and it is ready to be used for your plants!
