Coco coir blocks/bricks are a perfect growing medium and can also be used to start seeds or roots in a pot or planter.

​

Coco coir is like soil gardening but utilizes the basics of hydroponic gardening. Coco coir is the most effective media for water retention, absorbing as much as 10 times its weight in water. Coco coir bricks are great for hydroponic growing.

Container and Organic Gardening

Coco coir is a great product to use for container gardening. However, it is best used with additional media, such as perlite and vermicompost. Because coir retains so much water, too much can cause damage to plant roots, essentially drowning them. The addition of perlite helps the mixture dry slightly and allows you to better control the moisture levels in your mixture. Vermicompost is an organic composting media that utilizes various worms to break down plants and food waste, creating a nutrient-rich material that is perfect for plant growth.

Note

Coco coir is an inert substance, containing no nutrients. When used for gardening, it may be necessary to add nutrients in order to achieve quality plant growth. You will also need to look for coco coir that has been processed in fresh water because coir retains salt and, if it is processed in salt water, the salt can kill your plants.
