Thanks for your continued cogitation of this Keffka! The most popular non-water-soluble brand when I got to the site was Xtreme's version, and that contains Arbuscular Mycorrhizal Fungi and Rhizophagus intraradices. Our sponsored version lists theirs as Glomus intraradices, Glomus intraradices, and Glomus mosseae,
Those names are beyond me, so are they all just mycorrhizae as you would define it? I may have a tub of Great White somewhere (probably 6 or 7 years old now) so I'm going to go read the label to see if it's the same as yours.
Yes those are different species of AMF. There’s been some renaming and reclassification going on. Researchers realized that a lot of the initial names and classifications weren’t detailed enough. Some of the samples were too degraded to be accurate, cultures weren’t grown long enough, etc.
I believe the current name for Glomus intraradices is Rhizophagus irregularis. Glomus mossea is now Funneliformis mossea. These are species that form a symbiosis within the roots and their cells, usually forming what’s called an arbuscule to trade nutrients, exudates, and instructions. I’m sure even the names I know are in the process of being changed or updated.
Here’s a shot of the Great White for everyone who doesn’t have it:
There’s ecto and endo myco in this bottle, and below that there’s a list of the trichoderma and beneficial bacteria it supplies as well. You could see a benefit from the trichoderma, and bacteria, even after chasing off the fungus. The ectomyco is overkill as far as we know but it can’t hurt it.
Real Growers Recharge has some of the same ingredients, and that seems to work well in synthetic gardens. Although the organic acids do, do (heh I said do do) the heavy lifting in that product.
Unfortunately, this does mean that synthetic growers using certain myco products that contain only mycorrhizae and nothing else, are wasting their money.
