who wants to run a mycorrhiza experiment?

hello, new here, but long time gardener. and always curious.

does someone want to try an experiment?

for this somewhat scientific experiment you will need:
2 or more similar-sized clones (beans wont work as plants may differ too much)
pots
dirt
nutrients (mycorrhiza + beneficial microbes / tea / whatnot)
a host plant to grow myco fungi, like grass seed.

problem: every grow guide says to put the mycorrhiza in the dirt when you put the plant in the dirt.

theory:
if you grow your mycorrhiza and bacteria/microbes for 2 weeks (or more!!) in dirt before you put in your clone, will the plant grow faster than in a pot with a fresh innoculation of mycorrhiza?

experiment:
put your dirt, mycorrhiza, tea/whatever and grass seed in some pots and water them , keep them at a good temperature and lit etc.

after 2 (or more) weeks, put clones in.

you will have one pot with mycorrhiza growing alone (or with grass) for 2 weeks
and one pot with mycorrhiza freshly mixed when you add your clone to each pot.

please let me know if there are any problems with my theory or experiment. or if this has been done before.

i read a bunch of the mycorrhiza threads on this forum. i dont think mycorrhiza requires a plant to grow , theres plenty of things in the dirt for it to flourish.

this might only work with organic ferts, as non organic may give nute burns.

Things to increase myco fungi growth:
1. Addition of autoclaved oat kernels (oatmeal??) to a potting medium results in tremendous stimulation of shoot (and root) growth,
2. myco fungi do not do well with high Phosphorus. if your compost is high in P you need to use less of it. do not add any fertilizer with Phosphorus.

i will try to update this post as i get new information.

I got 4 baby clones that have not rooted yet, from different plants though. I am just getting in the organic side of things and would like to see people joining in, only since I grow 12/12 from seeds its hard for me to get many clones from the same plants. speaking of clones, I gotta run and bring the 4 girls inside for the night. I have not much experience with clones either, I am hoping I can get one to root out of 4... I will follow the experiment for sure maybe in time do it as well, are you doing it or have you done it?

Too many things cooking to start new project but all mycos are not the same. Mycos are actually a way to feed and accelerate the microbes that are already in the soil. You don't grow mycos you use mycos to grow microbes.
My short version is mycos enhance the roots ability to use nutes more proficiently and that results in more growth.
2 people testing same mycos are subjest to get a different result. All soils are different for best way to benefit with mycos;
Contact your local extension service to find out which "cocktail" of mycorrhiza fungi will work best for your plants.

Extension service does not want or need to hear about MJ but they can tell you what will work best in your soil for tomatoes and that will work with MJ.

mycorrhiza is the word for the relationship, not the fungus

but anyway... it couldn't hurt, but i don't see it proving a substantial advantage. the fungus is not going to grow too well without roots to adhere to

its a chicken and the egg question.

which came first, the plant roots or the beneficial fungi roots?

re: organic forum. i forgot that petroleum based fertilizer salts will build up and burn everything , you could run the experiment without ferts until your plants are in.

re: 2 people getting diff results: thats good too. science is about reproducing experiments. maybe we'll learn the proper ph for fungi to grow in? maybe we'll learn fungi grows quicker in low temps or warmer temps? maybe air pots are better or worse for myco? maybe one type of myco fungi does better than the other when its alone?

re: me doing the experiment: not right now. no clones atm. i know i should have done it myself. mostly i posted this to remind myself for next time.

Myco's need roots to grow on. They just don't 'grow' in the soil like bacteria, nor or they produced in a lab like some ad copy would have you believe.

the science on this has been done

we're not going to discover anything new here, sorry

Mycorrhizae needs the plant and it's roots. Skip the threads by questionable internet sources and instead read books by reputable authors with experience in horticulture.

You mean everything I read on the internet isn't true? I've been fucking lied to!

ok, what about starting the myco fungi with a host plant (grass seed?) before planting the clone in it?
that way the fungi has time to grow. my experiment is trying to show if myco fungi helps if its already established. the way to establish it may change (growing alone or with grass plant host), but its still the core question i want to get answers for.

this site has some tips for propagating myco fungi:

i guess reusing dirt (without composting) between grows will be similar to my experiment. i'll have to read up on reusing dirt (without composting) to see if it helps other people.

looks like adding co2 to your soil, (either by rotting plant matter, or possibly with an airstone? can someone check the full study?) will help the arbuscular mycorrhizal fungi grow larger. be interesting to see if that helps or hurts the plant.

Elevated levels of carbon dioxide did significantly increase the size of the AMF colonies
"We found that, under elevated carbon dioxide levels, AMF supply more nitrogen to their host plants by acquiring ammonium directly from decomposing residues,"

When there are higher carbon dioxide levels, the plant's ability to take in nitrates is inhibited and it then adds more carbon to fungi like AMF to acquire ammonium

Ok so I did this and I can say that it does work Bud tastes real flavorful.

However, thru much reading mykos doesn't do much just in the soil it needs to be in contact with the root.

what happen to the days of just growing weed in just dirt. nothing else but mother nature and god.. the shit was beautifull and got you just as high as today's weed ..

Mycorrhizae is a part of nature. It's a natural part of the soil outdoors. We're just trying to bring it inside so that our indoor plants can benefit from them. Just like they would if we all got to grow them outside with nothing but dirt, mother nature, and god.
