Coir, or coco fiber, is a more sustainably harvested and renewable alternative to peat moss. Coir mats can be used to propagate, grow microgreens, or line planters.

Some coir can be high in salts, which can interfere with the uptake of certain nutrients, such as calcium. If you plan to use coir as a hydroponic substrate, look for brands that have been washed or composted.
