Fungi are customarily viewed as unsavory plants, aside from tabletop mushrooms which many of us have become accustomed to eating. Generally, fungi growth can indicate a dangerous situation, so it makes sense to approach the subject with at least some hesitance, but once you learn what this incredible species has to offer, you might just find that your perspective quickly shifts to one that is more accepting of this essential component to all life on this planet.

What is mycorrhiza?

Mycorrhizal fungi are a fungus that grows in combination with the root systems of many different plants, and this relationship is found across all regions of the planet in nature.

When the fungi come into contact with the roots of growing marijuana plants, it works alongside the root system to create mycorrhiza in a condensed form. This gathering helps the plants to absorb essential nutrients, bring in plenty of water, creates the ideal environment for cultivation and helps to protect the crop against damage and disease.

Why are these fungi so useful when growing cannabis?

The reason the relationship between living organisms is so effective is, it is beneficial for both parties. The marijuana plants receive a constant supply of nutrients alongside a layer of protection, and the mycorrhiza fungi feed off the extensive root system. When one is thriving, the other will be doing just as well. Mycorrhiza fungi are also quite plentiful in most dirt, so its high presence and teamwork status makes it the ideal match for growing cannabis.

Are all fungi beneficial to growing high-quality cannabis?


Generally, if you see some form of fungi or mold growth, it’s a bad sign that can lead to root rot and a variety of other issues and symptoms that no one growing marijuana plants wants to deal with. So, most fungi are actually detrimental to anyone who is producing high-quality cannabis. However, some types of fungi occur naturally, which are suitable for most plants, like those that are found in super soils or living soils and use natural ingredients that will slowly break down as the plant matures to offer it a constant food supply.

How to get mycorrhiza fungi

Growing high quality cannabis doesn’t require any particular set of skills. What you will need instead are the right tools to provide the ideal environment for your crop.

It is also the most foolproof, which is ideal for both new and more experienced cultivators.
