Mycorrhizae Information

Summarized from "Soils in Our Environment", 11th edition, Copyright 2008:

Mycorrhizae are mutualistic associations between plant roots and fungi. In mutualism, both the member of the relationship (the plant and the fungi) benefit from the relationship. In a typical mycorrhizae relationship, the plant transmits organic substances to the fungi, and the fungi transmit nutrients and water to the plant's roots. The fungi extends what are called hyphae into the soil which can extend the length of a root 100-fold and can increase root mass by as much as 800%. The hyphae also help absorb nutrients, particularly phosphate, zinc copper, and molybdenum. Certain mycorrhizae also form a protective sheath around roots, and can increase tolerance to drought, high temperatures, and infection by fungal disease.

There are tow kinds of mycorrhizae - Ectomycorrhizal, (Ecto meaning outside) and Endomycorrhizal (Endo meaning inside). Ecto sheath the host root, and penetrate between the cells of the root's cotex where as endo penetrate into the host cells. Some of the hyphae of the endo form abruscular mycorrhizae (AM) which are particularly helpful in phosphate absorption. Endo are the most common form found on plants.

Benefits from myccorhizae have been shown in all major plant families except mustard. Regular applications of these fungi has also been shown to boost yield and increase disease resistance in most crops.

Mycorrhizae's relationship to a plant is also usually very species dependent.
There are benefits, but for many plants its minimal.
I don't mean to diminish everyones hopes, just don't start grinding ushrooms into your soil mixture

I wouldn't recommend grinding mushrooms into your soil mixture either, but the use of myccorhizae, particularly in the form of an aerated compost tea most certainly has very noticeable effects on cannabis.

Regular applications will greatly boost nutrient uptake, help prevent disease, increase root mass, increase drought resistance, as well as improve the structure, texture and moisture holding capacity of the soil.

These are the documented, scientifically proven effects of myccorhizae - they do work, and they work amazingly well.

ANYONE GOT ANY INFO ON AZOSPIRILLUM MAXIMUMYEILD.COM DEC 2009 ISSUE, I READ ABOUT IT THERE,INEED MORE LINKS TOO THIS INFO HELP

i use stuff called Great White, you should be able to find it at the hydroponic store, this is a product i use from start to finish. check it out

The information you'll here (on the boards) from experienced growers, is a much better source of valid information than the guy at the hydro store with no cannabis growing experience beyond selling you everything he possibly can.

Were cannabis an evergreen (not an annual) I'd say the addition of specific beneficials are a cost-effective benefit. Otherwise the benefits from adding costly beneficials are infinitesimal. (un-noticible)

Regarding compost teas...their original purpose was to kill insects and to spray on diseased plants. That didn't work, so some added molasses, kelp, nutrients to the mix. But that doesn't really work either because of the inability to control the plant's uptake, and lockouts and leaf damage can occur.
But my biggest problem with the teas, is listed below:
(wanna kill a med cannabis user that has lowered immunities...?)

If compost tea doesnâ??t do anything,
then how can it hurt to apply it?
â??While the scientific evidence is
certainly lacking for aerated compost
tea activity in disease control, there is a
serious, documented concern with these
types of compost teas,â?� says Dr. William
R. Schneider, a research scientist in the
Biopesticides & Pollution Prevention
Division (Office of Pesticide Programs) of
the Environmenatal Protection Agency.
He continues, â??It is very difficult
to do a microbial pesticide risk
assessment on a mixture of unidentified
microorganisms that could easily
contain human and nontarget organism
pathogens.â?�
Indeed, this risk is significant in
aerated teas that have been â??enhancedâ?�
with molasses, kelp, and other highnutrient
additives. Such aerated teas have
been documented through scientific
research to contain E. coli and Salmonella
populations, both of which are human
pathogens. The recent deaths due to
E. coli-contaminated spinach illustrates
how dangerous compost tea applications
can be, particularly on food crops.
