    Mycorrhizae, a term derived from the Greek words ‘mykes’ meaning fungus and ‘rhiza’ meaning root, refers to the symbiotic relationship between mycorrhizal fungi and plant roots. In the realm of cannabis cultivation, understanding the role of mycorrhizae is essential for optimizing growth and health of cannabis plants. This article delves into the intricacies of this relationship, highlighting its importance in the cultivation of cannabis, a plant with a rich and varied history detailed in our Cannabis 101 section.

    Understanding Mycorrhizae and Its Types

    There are two primary types of mycorrhizae: ectomycorrhizae and endomycorrhizae. Ectomycorrhizae form a sheath around the root’s surface and are less common in cannabis. Endomycorrhizae, however, penetrate the root cells and are more prevalent in cannabis cultivation. These fungi play a vital role in nutrient exchange, facilitating the absorption of water and essential nutrients like phosphorus and nitrogen, which are crucial for the healthy growth of cannabis.

    Benefits of Mycorrhizae in Cannabis Cultivation

    The incorporation of mycorrhizae in cannabis cultivation offers numerous benefits:

    1. Enhanced Nutrient Uptake: Mycorrhizae increase the surface area of roots, thereby improving the plant’s ability to absorb nutrients and water.
    2. Improved Soil Structure: These fungi help in creating a more porous and aerated soil structure, conducive to root growth.
    3. Disease Resistance: Mycorrhizae can enhance the plant’s resistance to root diseases and pathogens.
    4. Reduced Fertilizer Need: Due to efficient nutrient uptake, the requirement for fertilizers is reduced and in fact less is more, aligning well with practices of organic cannabis cultivation.

    (It is best for boosting organic grows: At low fertilizer levels, mycorrhizae increased plant biomass significantly by 86%. However, at high fertilizer levels, there was a decrease in biomass by almost 26%.,

    Application in Various Cultivation Systems

    Mycorrhizae find their application across different cannabis cultivation systems. In organic setups, they aid in nutrient cycling and soil health maintenance. Even in hydroponic systems, mycorrhizae can be introduced to improve water and nutrient uptake. Additionally, their role in pest management, as outlined in our pest management guide, is pivotal in maintaining healthy cannabis plants.

    Mycorrhizae’s Impact on Soil Health and Cannabis Plant Nutrition

    Healthy soil is fundamental to successful cannabis cultivation. Mycorrhizae play a crucial role in enhancing soil health, as they create a network of hyphae that improves soil structure and stability. This network aids in better aeration and water retention, vital for root development and overall plant health. The symbiotic relationship ensures efficient nutrient cycling, particularly phosphorus and nitrogen, essential for vigorous cannabis growth.

    Influence of Mycorrhizae on Cannabis Genetics

    Cannabis genetics play a significant role in determining the plant’s characteristics, such as THC and CBD content, flavor profiles, and resistance to diseases. Mycorrhizae indirectly influence these genetic traits by creating an optimal root environment and enhancing overall plant health. This healthy state allows cannabis plants to express their genetic potential fully. Our comprehensive cannabis genetics guide provides more insights into how genetics shape cannabis cultivation.

    Incorporating Mycorrhizae into Cannabis Cultivation Practices

    1. Selection of the Right Mycorrhizae: Depending on the cannabis strain and growing conditions, selecting the appropriate type of mycorrhizal fungi is critical.
    2. Application Methods: Mycorrhizae can be applied through soil mixing, root dipping, or as a foliar spray in certain formulations.
    3. Monitoring and Maintenance: Regular monitoring of soil and plant health is essential to ensure the effective symbiosis between mycorrhizae and cannabis roots.


    The role of mycorrhizae in cannabis cultivation is multifaceted and profoundly beneficial. Understanding and leveraging this symbiotic relationship can lead to healthier plants, better yields, and more sustainable cultivation practices. By integrating mycorrhizae into cultivation strategies, cannabis growers can enhance nutrient uptake, improve soil health, and support the expression of desirable genetic traits in their plants.
