Buyers Guide – Best Coco Coir For Cannabis
For many a year, parts of the coconut plant have been harvested as a food source that has offered many health and nutritional benefits, with the outer shell or “coconut husk” that is regularly thrown away and seen as a waste product with not that many uses.
Over the years we learned that this was not the case, and the husk, when broken down into various forms delivered some great results for the avid gardener.
When you think of coco coir, more often than not, it’s the outer coconut and everything else in-between the shell that is used in the making of coco coir.
Many beginner growers are unaware that there are actually two types of coconut fibers.
Brown Coir Fibers – These types of fibers come from matured coconuts that are considered to be ripe. They’re less flexible than white fibers but much stronger.
White Fibers – White coco fibers are weaker in nature but are much more flexible than their counterparts. They’re produced by pre-ripe coconuts.
The majority of home growers utilize the brown coconut coir within their hydroponic set-ups, this is mainly due to the first stage of harvesting whereby the coir is processed even more.
When looking for the highest quality and best coco coir, try to find out the following –
- How is it harvested?
- How is it prepared?
- How is it processed?
- Does the company do everything in its power to negate pathogen growth?
- Do they have a robust and methodical system in place to oversee the premature aging of their coconut coir?
- Do they utilize repeated wash and rinses to flush their coco coir?
- Is their finished blend a balanced mix of chips, fibers, pith?
- Is their coco coir stored correctly?
Recap
It’s always best to pick a trusted brand that follows the very best practices in the production process. The risk for pathogens in coco coir is fairly high due to the natural pH of the coco coir, and how it is commonly stored by manufacturers.
Because of this, most manufacturers of coco coir will chemically sterilize their coir before it’s sold to the public. This comes with risks to the coir, as the chemicals can quite often break down both peat and fibers. By following our advice, you can be assured you’re only picking the very best coco coir for cannabis.
