Pro Mix "Mycorise"...no mycorrhizal fungi!

[gojo]

Hi all,

Sorry to be the bearer of bad news but you don't have any mycorrhizal fungi if you relied upon Premiere. The product is called "Mycrorise" and it contains the beneficial bacteria "Bacillus subtilis", not mycorrhizal fungi . They get away with it by misspelling the word mycorrhiza...I complimed to the company that it's false advertising and many ppl think there getting ecto and/or endo myco's.

Good info gojo. When I used promix I used the HP with Micorize thinking I was getting Michorrhiza. Now that I'm in coco, I bought an innoculating powder that's supposed to have michorrhiza and other beneficials, I no longer have the package it came in so I can't give you an entire rundown.

Thanks. Sorry to head about that! I had to argue with the hydro shop owner before she'd believe me...I should've just not told them but I feel bad for ppl who are getting shafted!

It's important that your myco mix has the correct kind of mico's...most due but it's worth it to read this thread (it's in depth but interesting):

Hey SB,

yea i've used that before and the results seemed fine, alone the lines of other good spore inoculum...but recentlly I'm more of the feeling that infection with live hyphae, roots and spores is the best way to go...more on that topic in the comming months when I get my VAM cultivation ebb/flow tray setup...:farm:

Types of Commercial Mycorrhizal Inoculants

There are three types of mycorrhizal fungi inoculates commercially available endo, ecto and ericoid. Most are available in dry form. Ecto is in spore form and endo is available as propagules, i.e., spores, root fragments and hyphae. Endo in spore form alone is a poor inoculant if you want results within 6 weeks according to research that has been published. Research has shown that endo mycorrhizal inoculants with spores, root fragments and hyphae are superior to those containing only spores. Research shows that hyphal fragments are most infective, followed by mycorrhizal root fragments and then spores. Root fragments actually contain many spores and are better at protecting spores from adverse environmental conditions compared to spores alone. Ericoid is presently is in dry form.

Reasons why spores alone are dangerous for an inoculant:
1. Spores degrade over time, even when dried
2. For some species, spores are the only infective propagules and when they degrade the inocula are effectively dead.
3. For many species in Glomus [eg. VAM], hyphae from root fragments can be up to 10X more infective than spores.
4. Root fragments, when dried, are not as susceptible to degradation as spores, especially in a formulation containing high organic matter.
5. Ergo (from 4 above), even if part of the inoculum degrades with storage, infective propagules still can be present for a longer period in a mixed inoculum formulation.

The reality of inoculum marketers today is that most are just that "marketers". Some sell a single strain of mycorrhiza mixed in with a carrier backed with all the claims thousands of research studies will support. Some sell liquids. Some sell powders. Some sell only one kind. Some sell tablets. Most sell "cocktails" containing a variety of organisms. Some have formulated for numbers. Some for results.

One company that has been in the industry for 10 years marketed a transplant product for trees and shrubs which contained no beneficial bacteria package. What were they thinking not to include such an obvious package. Most landscape materials are planted in disturbed soils. What logic is there in not including a bacteria package? Bacillus subtilla, for example, is an effective "mycorrhiza helper bacteria".

hay lungus when you say cocoa is that the cocoa soil. Is this a step up from the regualer soil, the reason I ask is becuase eveytime I look at soil on a web page it has cocoa right next to it ,but more expensive.

PH2,

Not that I'm lungus, and I don't mean to step on his toes...but I think you should stick with the sunshine mix you're thinking about.

Cococoir is a substrate that can be used in place of, or in combination with peat for example. Coir has pluses and minuses (like all substrates), read this thread to catch up:
https://www.cannabis-world.org/cw/showthread.php?t=4535

C-ray says coir should be used in indoor grows, not outdoor, and I agree with him.

For you, as your just getting started in "soilless" medium, I think you should stick with a peat based premix. IMVHO peat is more forgiving then coir and if go with a nice pre-mixed soilless peat based medium you do well...then later, when you have experience with growing in soilless medium like peat you can mess with coir, etc...just my 2cents! ;)

BTW. the substrates you're referring to, like sunshine mix or pro mix, are not soil, they are "soilless". :farm:

HTH,

I know this is an old thread but.....
Is it correct?
Says on the package
"Mycorise® - endomycorrhizae inoculant"

Celticman you are right about the mycorise ->

premier has a mix with bacillus subtilis but it is called subtilex biofungicide -> http://www.premierhort.com/eProMix/Horticulture/Products/GrowingMediaCat/Biofungicide/fSubtilex.htm
