In this post, we will dig deep into growing vegetables in coco coir and why it is significantly easier than growing plants in traditional soil.

If you don’t know already, coco coir is an all-natural material made from coconut husks. It’s considered an environmentally friendly way to grow plants because it’s free of chemicals and helps preserve natural resources.

Basic types of Coco Coir: 

Coco coir can be off three types, coir pith, coir fibre, coco chips

Coir pith looks similar to finely ground coconut or peat moss. It absorbs water quite well and must be aged properly to use as a growing medium.

Coconut fiber adds air pockets into your medium which will provide oxygen to the roots.

Coco chips are a hybrid between coco peat and coco fiber. They’re large enough to create air pockets, but also absorb water so your plants won’t dehydrate completely. 

A good quality coco coir should have a proper blend of all three types of coir.

Coco coir Can Hold Water:

Coco coir is a highly absorbent material that has a water holding capacity of 3-4 times its own weight. It can be mixed with soil or used on its own. It will hold water for extended periods of time and slowly release it to the plant as needed.

This allows the grower to provide their plants with a consistent water supply without overwatering.

It Encourages Aeration in Plant Roots:

Roots need oxygen to survive and grow. Coco coir has very good aeration properties, allowing lots of oxygen through to the roots and encouraging the development of fine root hairs.

Coco Coir Is Fully Recyclable:

Coconut coir is not only a natural, organic product but unlike peat moss a renewable one.

Only waste products such as coconut shells are used to create this substrate. The process of creating Coco Coir from coconut husk does not involve chemicals or pesticides and no trees are cut down during harvesting or production.

After you use the coir to grow a plant, simply rinse the coir in filtered water, drain, and use again. So coir is not only environmental-friendly but also wallet-friendly.
