For orchid enthusiasts, in order to have orchids that are not only beautiful but also well-grow and healthy, finding an appropriate growing substrate is the key point. There are different types of media for orchids such as coco husk, sphagnum moss, fir bark, charcoal, perlite, or even some mixes of these substances, etc. However, sphagnum moss and coco husk are the common and most-used growing media for orchid growth. Let’s check some features of these media with EnvironSoil in this article.
Coco husk is considered an organic substrate that is widely used nowadays. When it comes to growing orchids, coco husk chips and coco fiber are 2 ingredients that are more well-known and widely used. Coco fiber is ground and shredded from coconut husks that have shaped like long strings. Coco chips are also made from coco husk but are cut into small pieces. These substances are usually mixed together or with other substances according to specific types of orchids to have the best results.
Character | Coco husk | Sphagnum Moss |
Price | Cheap, easy to find | High cost |
Aesthetics value | High | Medium |
Water retention capacity | Fast
Since coco husk is absorbent, they are able to absorb large amounts of water quickly | Excellent
Has fast absorption and hydration |
Breathability | Good
Coco husk has the ability to ventilate and retain gas even when containing large amounts of water without causing waterlogging of crop roots | Poor
If orchids are not equipped with airy pots, it will lead to waterlogging because of the high hydration function. |
Prevent pathogens | The good antibacterial ability of harmful microorganisms after proper treatment | Easy to absorb salt if not washed properly
Easy to generate pathogens |
Ability to maintain the original morphology | Good
Due to a large amount of lignin and fibrous structure, coco husk does not shrink and retain its original shape | Poor
It will gradually shrink. Also, when too much water causes waterlogging, it will decompose and become unusable |
Shelf life | About 2 years
After a period of use, coco husk chips will gradually decay into coconut peat and can still be reused with many other crops that still retain their inherent properties | Average 1 year
Because sphagnum moss has a topology, when reused, the roots of the previous crop will stick to it and there will be no breathable place for the latter to grow |
Treated products | Can be used immediately for plants because the ideal pH is from 5.8-6.5 | Have to soak with water for 24 hours to clean again, which is more inconvenient and time-consuming |
Characteristic | Benign and safe | Contains fungal spores that cause health problems |
After this reading, you can choose your own appropriate medium that will suit your orchid plant as well as your specific demands. However, it can be seen that choosing coco coir, especially coco husk, is gradually becoming a trend among orchid lovers because of its convenience and affordable cost. It can be said that coco chip is a quite suitable option for even newbies or longtime orchid growers.
