Coco for cannabis

Coco for cannabis

When you cultivate cannabis, you have to make many decisions. One of these is what grow medium to use. Coco for cannabis is a popular choice, thanks to the many benefits it offers.

When you use soil, you need to be sure that it fits certain criteria for drainage, aeration, water retention, and nutrient provision. Coco coir makes it easier for you to fulfill these growing requirements.

Below we define coco for cannabis and highlight some of its advantages. We also discuss its role in a hydroponic setup and compare it to soil. Let’s kick things off by explaining what coco for cannabis is.

What is coco coir?

Coco coir is made from the mesocarp of coconut seed husks. It’s an organic material that contains nutrients that assist with cultivation.

Before you can start growing weed in coco coir, you need to understand how it works. There are three components, each with its own advantages and disadvantages. These are:

  • Fiber
  • Pith 
  • Chip 

The best coco coir for cannabis is a renewable item, and it can be used thrice as a growing medium.

Coco for cannabis vs. soil

Many growers start their cultivation journey using soil as the primary grow medium. While this is a suitable natural option, there are some added benefits when using coco for cannabis.

Some cultivators opt to combine the two and create a mixture.

Let’s compare the properties of each substrate per the following criteria: 

  • Water Retention 
  • Nutrient availability 
  • Beneficial microorganisms 
  • Pest resistance 
  • Natural pH

Water retention and aeration 

The best soil for cannabis needs to allow adequate oxygen to the roots and drain well. Loamy soil is preferable compared to clay options. 

When growing in coco coir, your weed automatically has access to these benefits. The medium is fibrous, and it can absorb moisture readily and retain enough to keep the roots well hydrated.

Using coco for cannabis allows your plants sufficient aeration and drainage, which prevents overwatering.

Nutrient availability

If you check any coco coir grow guide, you’ll quickly learn that nutrients are vital for your crops to flourish. 

The substrate contains moderate amounts of potassium and phosphorus, but these don’t meet the basic requirements for weed to grow well. 

You’ll need to incorporate a cannabis feeding schedule into your cultivation practice. Your weed crops need calcium, nitrogen, magnesium, and other micronutrients in addition to what coco for cannabis contains. 

You should also consider booster supplements to facilitate optimal growth during each phase of maturity. 

Beneficial microorganisms

Growing in coco coir offers the added advantage of housing beneficial microorganisms. The grow medium provides the ideal environment for rhizobacteria and other organisms to thrive. 

These bacteria help break down organic matter and convert cellulose to carbon. These actions make it easier for plants to access the compounds they need. 

Pest resistance

When you use soil as your cultivation medium, your risk of common pests is relatively high. Even in the best soil for growing weed outdoors, you might find an unwanted creepy crawly lurking around. 

When you’re growing weed in coco coir, your plants are less susceptible to this issue. You’ll still need to keep an eye out for fungus gnats, but your overall risk of an infestation is reduced. 

Natural pH

Marijuana crops require specific pH levels to grow optimally. If the environment is too alkaline or acidic, they may develop poorly. When you use coco to grow cannabis, the ideal pH levels are easy to achieve. 

The grow medium offers pH levels that typically range between 5.6–6.2. Most weed strains require levels of 5.0–7.0, making coco for cannabis an excellent substrate for cultivation. 

Types of coco coir

Growing weed in coco doesn’t take a one size fits all approach. Different growers prefer different types of medium. It’s typically classified into pith, fiber, and chips, but some mixes offer a blend of benefits. 

Coco for cannabis

Coco coir pith

The pith of coco for cannabis is the part most growers favor as it’s similar to peat moss. The main advantage of using it as your grow medium is that it has excellent absorption properties. 

The main disadvantage of pith is that it doesn’t drain as well as other substances. It’s a good option if you’re planning on combining it with another medium such as perlite. 

Coco coir fiber

The fiber of coco coir for cannabis has a stringy texture. It provides adequate aeration and drains well. The challenge with using fiber is that it isn’t quite as absorbent as alternatives. 

The lack of water retention properties can lead to dehydrated crops. Mixing fiber with other options can yield excellent results.

Coco coir chips

Coco coir chips are quite large. They retain water well and provide excellent aeration. The biggest drawback of this coco for cannabis option is its size. Some growers take advantage of the medium’s properties by adding it to another substrate. 

Coco coir mixes

Some cultivators prefer using a coco coir soil mix for cannabis. These substrates vary from one grower to the next and are based on personal preference. 

Some of these combinations contain a blend of all three types of coco, while others combine pith with perlite or soil. Intermediate-level growers and those with advanced skills often make their own blends, while beginners buy ready-made mixes.

Quality coco coir

Coco is a renewable, environmentally friendly medium, but it needs to be prepared before using it for cultivation. The supplier cleans the best coco coir for weed. 

If you opt for cheaper coco, you can prepare it yourself by following a few simple steps. These are: 

  • Rehydrating the coco for cannabis
  • Rinsing the substrate 
  • Buffering the coco 
  • Refreshing it 
  • Adding soil, perlite, or another medium 

Nutrients for coco coir growing

The pH levels in coco for cannabis affect the cation exchange, leading to calcium and magnesium deficiencies. You can overcome this by introducing supplements to your crop. 

Coco for cannabis

When you’re growing cannabis in coco coir, you’ll need to administer the following nutrients on a feeding schedule liberally:

  • Nitrogen 
  • Calcium 
  • Magnesium 
  • Micronutrients 

Coco coir in hydroponic setups

Using a hydroponic system for weed cultivation is popular. Many growers are switching to this method. Coco for cannabis can enhance the benefits of hydroponics. 

Benefits of coco coir for hydroponic growers

Coco has excellent water and oxygen retention properties. The roots have more space to expand, allowing them to get stronger and healthier. In a hydroponic setup, coco for cannabis is user-friendly and doesn’t need to be monitored as closely as alternative options.

Coco coir problems

No grow medium is perfect, and growing weed in coco also has a few challenges. The first issue is that you may purchase a product of inferior quality. These items contain high levels of chlorine and sodium that aren’t good for marijuana. 

To ensure that your coco for cannabis offers your crops the right environment, it’s best to prepare it yourself.

Another issue is that if you purchased a pre-made mixture, the ratios might be off, leading to drainage problems. The ideal coco for cannabis must offer a proper balance of water retention and drainage. 

The last drawback is coco’s susceptibility to fungus gnats. Even though it repels most other bugs, this particular pest is attracted to coco.

Does coco coir produce larger yields?

The size of the harvest is dependent on several factors. The yield will be bountiful if the cultivator uses the best techniques and adopts the proper environmental conditions. 

Many growers report that the yields are substantially larger when using coco for cannabis. The grow medium should be combined with a strict feeding schedule and optimal conditions to produce better harvests. 

Coco for cannabis: Potting it

Coco for cannabis is an interesting grow medium with many benefits. Cultivators often use a blend of substrates to take full advantage of coco coir’s properties. 

You can mix the various types of coco or use a separate option like soil or perlite. Compared to soil, coco for cannabis has many advantages that make growing more convenient.
