Using Mycorrhizae for Cannabis Production

What is Mycorrhizae?
“Myco” – “rhiza” literally means “fungus” – “root” and describes the mutually beneficial relationship between the plant and root fungus.
Mycorrhizal fungal filaments in the soil colonize plant roots to improve nutrient and water absorption greater than the roots can without this symbiotic relationship.
Approximately 95 percent of plant species on the planet form a symbiotic relationship with mycorrhizal fungi.
Mycorrhizae Products and Inoculations
Mycorrhizae can be found added to many products and there are even products that contain concentrated levels for grower specific additions.
This is due to customer demand and the stated benefits this fungus can have on plants.
Mycorrhizae Word of Caution
Cannabis grown in mycorrhizae inoculated soils with Cd, Ni, and Cr(VI)to…
“significantly enhanced the translocation of all the three metals from root to shoot. The possibility to increase metal accumulation in shoot is very interesting for phytoextraction purpose, since most high producing biomass plants, such as non-mycorrhized hemp, retain most heavy metals in roots, limiting their application.”
Reference: Citterio, S., Prato, N., Fumagalli, P., Aina, R., Massa, N., Santagostino, A., … & Berta, G. (2005). The arbuscular mycorrhizal fungus Glomus mosseae induces growth and metal accumulation changes in Cannabis sativa L. Chemosphere, 59(1), 21-29.
Mycorrhizae Benefits to Cannabis
In growing substrates that are heavily amended and typically aggressively fed through out the growing cycle the benefits of adding mycorrhizae are likely reduced below economic return levels.
While no harm will come from adding this fungus growers must determine if it is worth the added cost when it comes to return on investment.

Great video! I’m wondering if my synthetic nutrients are killing any mycorrhizae that i put in the soil. I’m using the Flora 3 part nutrient mix.
Hello, professor. Your channel very interesting for me! Really underrated. For today i`m test using glomus with non-ionic surfactant directly on roots of plants, because glomus works with directly roots contact only. I grow test plant in dwc. What do you think about this method?
Second question: If I grind roots from one plant, inoculated with glomus(healthy plant) can I using this like glomus inoculant for another plant?
solution: addition of mycorrhizae inoculants at certain physiological stages , timed with fertigation schedules , constantly measuring nutrient levels with soil probes and visually observing plant status . this will help show whether nutrients are taken up by mass flow (no mycorrhizae ) or symbiosis with fungi.( showing increased vigor without nutrient applications)
👍🤘✌
There is a robust body of peer-reviewed research conclusively demonstrating that commercial inoculants applied to plants in landscaped soils have no substantial effect on the development of mycorrhizae. This lack of efficacy has induced some inoculant manufacturers to add fertilizer, especially nitrogen, to increase plant growth and fool consumers into thinking the inoculant was responsible.
I have noticed a lot of extra root growth since using media with mycorrhiza , even have to cut pots off from time to time when transplanting !
Every transplant gets the treatment. So far so good. Seems to be after a few weeks the plants exploded
Can I add this to my living soil while it’s in the cooking process? Will it be beneficial?
Please help I’m approaching the last 2 weeks and I’ve discovered a mushroom near the stem is this ok? I used mycorrhiza when I transplanted them and this has never happened also the plant itself has not grown normally its very leafy as if I’ve tried to regenerate it yet its in a 11-13 cycle
These are excellent training videos for new hires. Well done.
Always good information
Thank you
I’m using rhizophagus intraradices with raw salts in hydroponics. Glomus working well, but not cheap, because I need to use him every week(they spores not grow in salts). But glomus produce more hormones, like auxin. With him plants grow much faster. What do you think about using glomus in hydroponics for cannabis, professor?
Hey fella been using this for about five years for transplanting and it works great but I wonder if there’s any benefit in adding mycorrhizal powder to water and watering into the roots from time to time or is it a pointless waste of time money and energy
(All of which I have less of these days)
Enjoying all the uploads🌞
So how does Mycorrhizae help cannabis newly cut clones to develop roots on an aeroponics system? clone phase does not have any much nutrients to being with. Would Mycorrhizae be useful during clone phase to help cannabis root and avoid fungi pathogens rather than nutrient uptake? During clone phase, is it better to use "Mycorrhizae" or "Trichoderma"?
Why do I always see "Trichoderma" as the only fungi ingredient on commercial "Mycorrhizae" fungi products? The "Mycorrhizae" fungi is not listed on the ingredients for Mycorrhizae fungi inoculant products.
Professor DeBacco, I wonder what your thoughts are on this.
People say "bigger roots = bigger fruits" and people say that a large root system on a Cannabis plant leads to a larger harvest.
So if a grow has Mycorrhizae assisting the root system by bringing it water and nutrients, wouldn’t that lead to the plant not needing or wanting a larger root system and thereby actually working against the idea of bigger harvest?
Or is it simply that a non mycorr grow needs larger roots to uptake the same amounts that a Mycorr+ grow would uptake from a smaller root area?
I am a very new grower in Thailand and all I can say is that I transplant into 5 gallon fabric pots with Mycos and Azos and the plants explode within a few days. I also water in with Azos.
Would you do an episode on Azos for me?
I love your channel. thanks for helping me understand my plants.
I wish you were my teacher in real life! I almost watched all your videos
Professor DeBacco, I have watched and learnt most of what I know from you 👏👏,thing I want to know is, when do I get my diploma?😁
Bro, you are awesome.
great information mate
