Cannabis and mycorrhizal fungi

[TychoMonolyth]

I could have found this on the old site, but I'll be damned if I can now.

There was a discussion on mycorrhizal fungi in which a study posted in here showed Cannabis only (or close to it) used one specific fungi. Along with the study, people were posting the brand/product with the most. Can anyone help me track this down? With the outdoor season almost upon us, it'll come in handy.

The brand was probably Mykos.

I thought it was three Tycho??
40.

Could be.

Nope. Not GW either.

It didn't have a huge list of "beneficials".

 

[Gaussamer]

Mykos has a pure mycorrhizae, not sure you can find another brand with more than that. Keep in mind it's an inoculant, how pure it is really only matters to your wallet in reality.

ENDOMYCORRHIZAL INOCULUM – PTB297 Technology
Glomus intraradices: 6000 viable spores/g

That's the one that the new Pro Mix Connect uses, https://indoorgrowingcanada.com/products/pro-mix-connect-mycorrhizal-inoculant

I'm happy with mykhorriza soluble from gluckspilze.com . Has an a lot of beneficals in it and can be used for whole gardening.

 

[chilliwilli]

Iirc white clove shares some mykho with cannabis. So a cover crop with it can help to re inoculate new seedlings/clones

Ah... that's it.

I'll be inoculating 3 yards of soil mix in April for this season.


Promix is my usual goto brand, but I think WoW (Wallace Organic Wonder) https://wallacewow.com/products/best...5-10-20-pounds is where I'm going.

Promix says "6000 spores/g" and WoW says "300 propagules/g". I'm assuming they're the same unit of measure. If I was doing pots, I'd use the Promix.

WoW is $87 vs Promix for $195 - 5 lbs.

 

[TPFTFW]

Yeah can anyone explain what the difference in those terms are.. propagules vs spore colonies vs spores etc

 

[clearheaded]

well propagules count spores and peices of hyphae myc etc per gram.. so in one hand if fresh hyphae should grow faster then spore by a few days at least. but spores are likely to last longer in storage and there is no way to know if 99%is spores and 1% others in the propagules count. more concentrated isnt better as harder to get over larger surface area but if same price per gram then the higher count the better. spores might weight more then hyphae but still. CFU colony forming units i think is the same as propagules. and spores is just spores per gram. keep in mind u could make alot of propugules depending on how fine u chop the pieces up.

dynomyco i think uses the same glomus and prob cheaper.

 

[chilliwilli]

Imo propagule is more a term for plant seeds and all the other reproductive stuff.
U determin the cfu via growing out the spores on agar so its the better unit imo because it gives u the number of viable spores.

TychoMonolyth I think you're referring to the following thread.

Also maybe check out the post I had made into that thread.

How I understand it there is according to current scientific research indeed only one mycorrhizae that creates an interesting symbiotic relationship with Cannabis: Glomus Intraradices (aka Rhizophagus Intraradices).
There are several other mycorrhizae which create a symbiotic relationship, but current research shows that these aren't all interesting and might even be detrimental.

Also don't confuse endophytes with endomycorrhizae.

Here is a link to an interesting article
https://groweriq.ca/2018/11/29/living-soil-improves-cannabis-growth/

And a link to the scientific research that is mentionned in the above article about Glomus Mosseae. Which shows that G. Mosseae might be detrimental for Cannabis.
https://www.sciencedirect.com/science/article/pii/S0045653504009634

This doesn't proof that only Glomus Intraradices (aka Rhizophagus Intraradices) is the only interesting mycorrhizae. Maybe future research shows that more mycorrhizae form an interesting symbiotic relationship with Cannabis. And maybe that future research shows that G. Mosseae might be usefull for the uptake of micronutrients.

Edit: Glomus Intraradices is indeed the old name.
Recent molecular analysis of Ribosomal DNA suggested that Glomus Intraradices is not in fact in the genus Glomus at all, and should be renamed Rhizophagus Intraradices.

That's exactly the one! Thanks.

(Gotta keep moving the goal posts.)

I see Myc. and related fungi when I rake the soil & sometimes when I put it in bags and carry it down the hill for a home grow.

If you have a pile of bark fines or other soil mix, and seed it with fresh primo samples from a nearby forest, don't you see some of those gray streaks of fungus growing ?

I like Great White because it's full of goodies.

I'd use GW in my veggie garden, but if cannabis benefits from one type? That's why I'll use Wallace WoW.

 

[Douglas.Curtis]

I'll vouch for Wallace's Organic Wonder. Inexpensive and only the fungi known to work with cannabis included.
