Benefits of Coconut Coir

Coconut coir’s primary benefit that most growers boast about is its improved water retention ability, including its ability to be easily re-hydrated. At the same time, coconut coir also possesses aeration properties which is important in soilless growing. Because of these two factors, plants grown in coconut coir – or a coco coir mixture – experience stronger root and better health overall because of its neutral pH level.

This inert and sterile grow medium is bacteria free which will prevent plants from developing diseases, pest infestations, or fungus growth. Coconut coir has a natural composition of lignins, which are a natural polymer that encourage the growth of beneficial bacteria in gardening capacity.

For many growers, the fact that coconut coir is an entirely renewable resource is an important benefit to consider when choosing your grown medium. Its environmental sustainability often gives it the edge over other alternatives like peat moss.

Coconut coir is a great soilless substrate to use in a tray system when growing wheatgrass or microgreens. It can also be used in pot systems for growing vegetable plants including leafy salad greens. It works great in either passive or active hydroponic systems because you can count on its ability to retain moisture.
