Hi,

I have been inoculating my seedlings with Xtreme Gardening's Mykos and the soil keeps growing what appears to be mold. How can I tell if this is the Mycorrhizae or if it is mold?

Thank you

[mdgg4]

if its white fuzzy looking stuff its indeed mycellium, probably not spelled right but thats good shit you got growing in your medium. if it was a fungus or mold you would definetly smell it. what the roots look like?

PEACE!

they are one in the same. mold is a fungus. Mycorrhizae literally means fungus in the root zone. Mycorrhizae can be good, bad, or neutral to the plant. chances are if your plants are not dying then it is either a good or neutral fungi.

Thanks for the replies.

It's hard to tell the color at this early stage. Looks white(ish) but that could be wishful thinking. I will check on the color daily though as it progresses. Edit: [I just watched this crappy video https://www.youtube.com/watch?v=lZVniNFTWh4 and apparently mycorrhizae are white and green]

If it's potentially mold, I'd rather not get close enough 2 smell it and 21 years of smoking tobacco have destroyed my sense of smell.

Usually, I germinate in paper towels then transfer to peat containers. Last batch had a growth in the soil and the container so I threw it out b4 remembering I had innoculated them. Didn't look at the roots.

This batch, I just popped the seedlings in expandable peat pellets a few days ago. Not even sure if they have sprouted yet, but b4 I throw them out (if it comes to that) I will have a look at the roots.

I read mycellium can't survive without roots so hopefully it's a sign that they rooted already. I also used twice the recommended dosage this time so I can't call it.

From what I read, mycorrhizae means mutually - beneficial fungus as opposed to pesky mold.

I hope you're right, but I've heard several stories of people harvesting mature moldy MJ and the dangers of smoking it, so I would appreciate a 3rd/4th/20th opinion if available. That's a slightly different situation tho, as humidity should be lowered during flowering. I guess time and a magnifying glass will tell tho.

i would get rid of anything on the surface with a mild h2o2 solution, if its the colony intended and growing all over like that its plenty healthy to benefit your plants and belongs near the roots anyways, drive it back! lol

if it disappears with a few sprays consider it a pathogen avoided and keep it knocked down, where theres smoke theres fire, i personally wouldnt encourage that kind of stuff

happy growing and good luck!

I just bought about 20 cubic feet of steer manure.

Every third bag had a big streak of gray, like it was celebrating its 45th birthday or something.

Sounds reasonable. Thanks.

Manure & fungi ... like PB&J

As already pointed out mold and fungus are one in the same. Many scientific papers use the word mold (mould) to refer to fungi.

You have not even stated what species of mycorrhizal fungi you are inoculating with. This is the trouble with the commercial growing industry. All these miracle fixes are sold to consumers with no educational material on how the product functions.

Usually the seller does not know themselves. Disgusting.

If you are growing cannabis, then endomycorrhizal fungi is the type you should be using. The most common species is Glomus Intraradices (Rhizophagus intraradices) followed by Glomus Mossae. These infect root systems as microscopic hyphae and appearance on the soil surface is rare. This could occur after heavy infection [infection being good] and frequent use of topfeeding.

If the so-called mycorrhizal product you used is mixed with trichoderma and/or ectomycorrhizal species then these could very well form mycelia which will appear on the soil surface. Trichoderma is a good thing and not a worry, however it likely means there was no infection by endomycorrhizal fungi.

I do not personally like seeing fuzzy fungi on the soil surface and I generally turn it under, cover it with mulch or stop watering too much. I have posted photos in this forum showing the difference between good looking fungi and suspect fuzz.

If it begins climbing your plants, you'll know you have a pathogen.

It's always good to research thoroughly BEFORE acquiring a product.

Thanks for entering the conversation, Microbeman

I got it the first time. That's like me asking for the difference between apples and oranges and somebody goes, "It's all fruit, baby!" That wasn't the question and maybe I'm allergic to oranges so those answers are the opposite of helpful. I never used the word fungi in my OP because I'm not looking for any old fungi. But if it helps someone else's understanding of the issue, I guess I'll allow it.

As mentioned in OP, I am using Xtreme Gardening Mykos. According to the website,

"This single species of arbuscular mycorrhizal fungi contains only Rhizophagus intraradices, formally known as Glomus intraradices. "

Interesting. More from the site:

"Mykos does not contain any other microbes such as trichoderma or ecto-mycorrhizae."

I will look 4 those photos, appreciate it.

Before AND after, I agree. That's why I'm here. That's why I've been studying Cannabis and mushroom growng for 20 years in my limited spare time, and that's what got me interested in mycorrhiza many years ago. I'm far from a know - it - all, tho. Education is a life-time pursuit 4 me.

[Microbeman]

My bad, I should have looked up the species or known it. That is good that you are not using other inapplicable species mixed in. If you inoculate seeds or cuttings in peat pellets or some other media where the roots poke through you sometimes will see even tinier 'spikes' coming off the roots which I believe are an indication of infection by AM.
