Coco coir is one of the popular growing mediums in the hydroponics world. It was used to grow roses and lilies in Holland during the 80s. Since it worked so well in promoting vigorous root growth, hydroponic cannabis growers started using it in place of peat moss.

Derived from coconut hull, coco coir is made out of the fibrous materials between the actual coconut and its outer husk.

Canna Coco is one of the premium kinds of coco coir. It is fine compressed into a block, not steamed. It is certified as free from chemicals, viruses, and diseases.

Coco Coir as a Potting Medium

Coco Coir as a Potting MediumCoco coir bricks are expanded up to six times its original size by simply adding water. There is no need to worry about adding too much water when re-hydrating. Excess water just drains off as well as when watering the plants.

This makes coco coir one of the forgiving mediums since it’s not possible to overwater the crops or have a soggy grow medium. Also, it retains plenty of water in its tube-like fibers even when it feels dry to touch so not much water is needed as other mediums would typically require.

It is an excellent medium to use for indoor plants, either mixed with other material such as potting soil or perlite or on its own as a soilless grow medium. Likewise, it can be used as a potting medium and each pot should be filled loosely with coir.

Repotting is just as simple. After wetting the coir thoroughly, turn the pot upside down and tap firmly while supporting the plant until it slides out of the pot. Add coco coir to the new pot as needed and place the plant into its new container. Then, fill the new pot with more coir and water adequately.
