Growing weed in coco soil

Professional cannabis cultivators all agree that drainage and aeration are key to a successful crop. Many achieve this by using coco coir as their growing medium. Coco coir, if you’re not familiar, is produced from the humble coconut, specifically the fibrous material found between the husk and the coconut itself. This material holds water well but also allows for good drainage. (I know it’s hard to wrap your brain around being both water-holding and water-draining at the same time, but let’s chalk it up to science.) Well-draining growing media allows for good air flow, which is good for root growth. And a good, healthy root system is the secret to a great crop of pretty much anything, including cannabis.

Watch for salts. If there is a downside of coir it’s the fact that the product in its raw form contains salts. You, the end user buying coco coir products, don’t really need to worry too much about the salt level because it has been processed and washed extensively before you receive it. But if for some reason you’ve found some compressed blocks of raw coir, do know the salts need to be rinsed away or else it can harm your crops.

What Is Coco Coir?

Cocodelphia is also ready to go straight out of the bag. Add in some other beneficial amendments such as Biochar Blend or Worm Castings for a punch of nutrition. Or plant in the bag and save yourself the time of potting.

The Science of Coir

We at Organic Mechanics think our Cocodelphia coco coir product is one of the best on the market. Why? For one thing, we buy our coir from just one farm in India, so our variability in quality is essentially non-existent. That farm washes the coir several times and relies on the monsoons of Southeast Asia to accomplish this. Once we have received the coir, it’s washed again as we rehydrate the air-dried, compressed coir blocks. Essentially, Cocodelphia is triple washed.

In order to properly manage substrate moisture and nutrient availability in coco coir, it is important to understand a few key terms. Saturation describes the total volume of water a substrate can hold by percent of substrate weight, or the water holding capacity (WHC). Field capacity describes the available water content in a substrate after excess water has drained. Permanent wilting point occurs when there is no remaining moisture available for plants to extract from the substrate.

Coco coir substrates are a popular choice for cannabis cultivation. Coco coir is a sustainable and renewable resource and can be easily composted after use. It can be purchased loose or compressed (for growing in containers) or in compressed grow cubes (as an alternative to rockwool blocks). Coco coir can be used once and discarded or used as a top dressing for raised beds and feld soil to increase organic matter and moisture retention in heavy clay or sandy soils.
