How do you choose the right mycorrhizal product for better business?

When it comes to competitive markets, the cannabis industry is up there. To increase profitability, growers are trying to find their edge. Most businesses and cannabis lovers want to discover a way to produce better quality cannabis at a reasonable cost. But how? Premier Tech's latest article explains.

This is when active ingredients come in. Active ingredients, such as mycorrhizae, offer incredible advantages for your culture, and ultimately for your business, which should not be neglected.

However, with all the mycorrhizal products available on the market, how do you know which one is reliable and will provide actual results? Some might benefit your plants, but most will have no effect on them. Although mycorrhizae are a fairly well-known topic in the industry, they’re still not fully understood by the community. That, paired with the wide selection of products available to growers, makes it hard to make an informed choice when buying a mycorrhizal inoculant.

So what considerations should you have when assessing whether a mycorrhizal product is worth the investment?

Propagules VS viable spores
What makes the number of viable spores more important than the number of propagules?

Let’s start from the beginning. Mycorrhizae are a beneficial symbiosis between a mycorrhizal fungus and the roots of a plant. Many positive effects of this symbiosis on cannabis plants are well established (Table 2).

When viable mycorrhizal spores sprout, they develop hyphae which explore the soil for a root to colonize. Vesicles and arbuscules are created once the hyphae enter inside the root. More hyphae will then grow out of the new vesicles and spread in the soil to attain nutrients and water. The nutrients and water will be brought back to the plant and exchanged for carbon (lipids/sugars).


Table 2 

When mycorrhizal products are identified as propagules, it entails that they are not filled with exclusively viable spores. Why does that matter?

Like seeds for a cannabis plant, spores are how fungi reproduce. Only viable spores can create a mycorrhizal symbiosis with the roots. Because of that, a product, to be worth it, needs to indicate that it contains viable spores.

In short, you should always seek a mycorrhizal inoculant that indicates its concentration in viable spores or at least guarantee its propagules’ viability. 

Not all mycorrhizae products are equally effective
Not all mycorrhizal products are equally effective, especially when it comes to short crops like cannabis, where you have little room for mistakes. To see its full benefits in the plants, the product needs to work fast and well. There are three factors to consider when choosing a mycorrhizal inoculant:


Table 4 

Designed for cannabis growers, PRO-MIX Mycorrhizal Inoculant CONNECT has been specially created with these three factors in mind: viability, concentration, and application. It’s the most concentrated inoculant on the market, with its 6000 viable spores per gram. So, when transplanting, applying CONNECT as a slurry on rooted cuttings will put around 30 000 viable spores in direct contact with the roots. The symbiosis will take place quickly.

Analyzing the product performance
Testing two different products for comparison purposes can be a difficult process. Many cannabis growers will apply different products to different plants and set up a demonstration to verify their efficacy. However, with all the variables and possible fluctuations in compaction, lighting, fertilization, temperature, ventilation and more, testing various products that way will not give statistically significant results.


Germination and root colonization of mycorrhizal spores 

In controlled conditions and following rigorous scientific protocols, Premier Tech analyzed the product efficacy and viability of several mycorrhizal inoculants available on the market. Premier Tech was verifying if the product tested contained the guaranteed number of spores they indicated and if these spores were capable of colonizing a cannabis plant in a timely manner.

PRO-MIX CONNECT was the most concentrated product (proven by a spore count test). It was also the only product to colonize every single plant, 100%, with a 40% root colonization rate. The nearest competitor colonized 63% of plants with only a 5% root colonization average. Out of seven products tested, four did not colonize plants at all.

For a better terpene profile, bigger yield, and higher cannabinoids concentration, the cannabis plants’ root system is essential. Spending more for a great quality mycorrhizal product with a high viable spore count is worth it in the end. It ensures faster growth with less vegetative time, increased resistance to stress, larger yield, enhanced trichome density, better potency (THC, CBD, etc.), and improved terpene profile.
