Mycorrhiza and Trichoderma

Mycorrhiza and Trichoderma: Two key organisms for healthy soil and productive cannabis cultivation

In the world of organic farming, especially cannabis cultivation, there are two microorganisms that are increasingly gaining attention: Mycorrhiza and Trichoderma. These fungi each offer unique benefits that have a positive impact on plant health, nutrient uptake, and the overall soil ecosystem. On this page, we'll explore the differences and benefits of both organisms, specifically in the context of living soil and cannabis cultivation

Mycorrhiza: The symbiotic nutrient supplier

Mycorrhizal fungi form a symbiotic relationship with the roots of plants, expanding the plant's root network and improving its ability to absorb nutrients and water.

Benefits of mycorrhiza in cannabis cultivation:

  1. Improved nutrient uptake: Mycorrhizal fungi increase the root network and improve the uptake of essential nutrients such as phosphorus, potassium, nitrogen and micronutrients. For cannabis, this means faster growth and a more robust plant.

  2. Increased water uptake: By increasing the size of the root system, mycorrhiza helps plants use water more efficiently during dry periods.

  3. Protection against pathogens: Mycorrhizal fungi strengthen the immune system of plants and help to ward off harmful soil pathogens.

  4. Better soil health: Mycorrhiza contribute to soil fertility by breaking down organic material and thus improving the availability of nutrients in the soil. In the long term, they stabilize the soil structure and contribute to the formation of humus.

  5. Long-term symbiosis: Mycorrhizal fungi establish themselves in the soil over the long term and support plants over several growth cycles.

Trichoderma: The soil guardian and disease fighter

Trichoderma is a soil-dwelling fungus that is particularly known for its antagonistic abilities against plant pathogens. While mycorrhiza forms a symbiotic relationship with the roots, Trichoderma is primarily known as a biological protective agent.

Benefits of Trichoderma in cannabis cultivation:

  1. Disease suppression: Trichoderma fungi are known for their ability to suppress harmful pathogens such as Pythium, Fusarium and Rhizoctonia. This is done through direct competition, with Trichoderma taking up nutrients in the soil faster than the pathogens, or by producing enzymes that attack and kill the pathogens.

  2. Improved root development: Trichoderma can stimulate root growth and branching, leading to better nutrient uptake and overall healthier plant growth.

  3. Increased stress tolerance: Plants treated with Trichoderma are more resistant to abiotic stress factors such as drought, saline soils or fluctuating temperatures.

  4. Fast establishment: Compared to mycorrhiza, Trichoderma is able to establish itself very quickly and exert initial positive effects on plant health. This makes it particularly useful in emergency situations when pathogens are already present in the soil.

Mycorrhiza vs. Trichoderma: Differences and synergy effects

Although both types of fungi have different functions, they are not mutually exclusive. In fact, mycorrhiza and trichoderma complement each other extremely well and can be used together to optimize soil health.

  1. Different modes of action: While mycorrhiza enters into a symbiotic relationship and improves root growth in the long term, Trichoderma acts as a “watchdog” in the soil, fighting pathogens and stimulating root growth in the short term.

  2. Synergy effects: In a balanced soil, both fungi can work together harmoniously. Mycorrhiza improves nutrient uptake, while Trichoderma protects the plant from pathogens. This combination leads to a healthier, more resilient root system.

  3. Application: Mycorrhiza is often introduced during the cultivation phase, as the symbiotic relationship takes time to develop. Trichoderma, on the other hand, can also be used in later growth phases or when there are problems with soil pathogens.

Conclusion: The perfect combination for successful cannabis cultivation

Both mycorrhiza and trichoderma play a crucial role in the sustainable cultivation of cannabis, mycorrhiza strengthens long-term nutrient uptake and plant growth, while trichoderma offers quick help with disease control and root development. That's why we at Love Living Soil have decided to use both organisms.

The combination of these two organisms creates a stable, healthy soil microbiome that provides cannabis plants with an optimal environment for growth and resilience.
