Funges and your Plants?! (Mycorrhizae Roots)

So I recently read about the fact that certain types of fungeses that can be obtained to mix into you plant medium can greatly help benefit the nutrient uptake in your plants roots. Farmers use this technique with corn and other crop and it increases nutrient uptake by quiet an amount, some cases double to triple what your roots are capable of on their own. It specifically helps in the uptake of Phosphorous in your plants roots. I'm thinking this would be benificial if you were growing outdoors instead of indoors or hydroponically considering there is really only so much space for your roots to spread, when not just freely spread throughout the ground. I'm wondering if anyone has messed around with this method of Mycorrhizae roots? An if you have what'd you come up with as far as your increase in growth, yield, and overall product?

Many organic growers make use of mycorrhizal fungi and in recent years more products containing mycorrhizae\biologicals have come to market. They've already been incorporated into some plant foods such as Espoma Bio-Tone, then soil and soil-less mixes such as Fox Farm's Happy Frog, Light Warrior as well as Pro-Mix Organic and Sunshine Advanced Mix #4. Additionally there are a variety of products for inoculating with myco such as Rooters Mycorrhizae and Great White. Many brands of modern grass seed come inoculated with strains of endomycorrhizae, this is where the water-saving and increased growth capability comes from.

There's a sticky in this Organics Forum that has a lot of info on mycorrhizal fungi (MF). I recommend that you take a look at it.
Spores are available that can be added to soil mix but I believe that MF will form as long as you don't add excessive synthetic fertilizers or pesticides, add a decent amount of compost to the soil, and plant cover crops in the off season (especially plants which are known to readily attract MF). Sythetics create hostile environments for MF while compost benefits them. They also are very dependent on plant roots and will not grow without them (though their spores might remain in the soil). That's why I overwinter my soil with a cover crop.
I hope your interest in this crucial soil organism leads you toward the pursuit of even more soil food web knowledge.

That's interesting, yeah I was a curious if it was already in a mix that you could purchase to mix into your medium. You both might know something about Gibberellic acid then? I've read that it helps in the elongation of shorter plants as well as the increase in flowering plants and their fruit production. I've heard you can buy it as a spray to mist on your plant. Does this have any affect on your yield and size of your buds when your plants start to flower? Is it seen as an organic way to grow if used cuz I've heard its all natural but nobody wants to smoke harsh bud sprayed down with chemicals?

The number one natural source of things like gibberellic acid, auxins and other plant growth hormones\PGRs would be kelp meal, or a cold-pressed liquid kelp or an extract. Certain microbes are also known to produce them.
