Let me start off by saying Im a super noob & reading through this thread seems like "michs" is something I should know about. Can somebody give a brief explanation on what "michs" is & the benefits please, also It would be really helpful if you can name some brand that have it readily available in Hydro stores.

Not exactly.. Bad proportions of chemical ferts may kill them, but then again, so will bad proportions of organics because they do infact break down to the same compounds as chemical ferts are made of..
Organics also provide a plethora of compounds beyond the typical NPK salts though, and microbial life tends to require these.. They don't need to come from organic ferts though.. Well they do I guess, but healthy soil is more organic than some ppl realize.. You don't necessarily need to add more organic products though, and proper addition of salts won't hurt them if they are types that are indeed symbiotic with cannabis..

Great post. High P foods can kill this group of fungi. If I was doing soil-less, ecto and endo forms of myco might be beneficial. Only by running a control group can you get an answer.

If you are stupid enough to buy Voodoo Juice (or anything AN sells for that matter), then you deserve to get burned. 1 l. for $69?????? I bought a product for $39 that makes up to 200 gallons of a soil drench, and that's a one time hit too. For starts, "Voodoo Juice is not a mycorrhizal mixture." http://www.hydroempire.com/store/product_info.php/products_id/504?osCsid=433d781fceebacb62ca878f16497b9a1

Buyer beware!

I'm always telling ppl to look towards the agricultural sector for soil products, and the contracting sector for lights/hardware.. The hydro-store is a good place to get phosphoric acid for pH down, and rockwool/H2O2 if you need those, but for anything else its analogous to buying candles for $25 from some store that also sells crystals, and fertility statues..:)
Here are a couple products I found that are intended for large-scale application..

I got a vasectomy early on, so the fertility statues were never a "big thang" for this here bendejo.

Deals with a fungicide.

Very limited amount of species (3) and only one kind, endo. There are many species that thrive under different environtments regarding temp, moisture, soil structure, pH, etc. This brand covers all conditions by providing a broad array of species.

"VAM" is just another "confusing" label for the basic fungus spores.

Thank you Uncle Ben. I can't add any meaningful feedback right now, but I wanted to acknowledge your scientific approach. Most of the comments on the web come from folks who have no clue of how to go about objectively evaluating nutrients, supplements, and technique. I will be interested to hear your findings. I have been inoculating with fungi and bacteria, but have not done a controlled study. I grow in a hybrid media composed of coir, perlite, and a small amount of compost/peat moss. I end up with a very healthy dense root matrix, but really don't know if the fungi and bacteria make a difference in development and nutient uptake. Please keep up the good, objective, and valuable research. Thank you for sharing.

Thanks for the nice post. Let's put it this way....none of the stuff we're experimenting with is of ANY value without a control group (non treated) to compare it to. Without using a control group, such "results" will reflect the never ending cannabis forum drill of folks seeing what they expect (or hope) to see.

Have fun,

This is the first time I have used this supplement....I am growing in DWC in a 4'x4'x6' box....scrog style.....the first yielded 17oz with 1 600wt, the second 15oz of heavily crystallized bud (attr lower amount to extreme cold temps and low humidty through most of the grow -stunted-), the 3rd running right now has the addtn'l supplements. I have noticed the diff.....It might be my 3rd grow, but I have been around it for some time....The growth I am experiencing right now at day 24 is ASTOUNDING....I have added a second 600wt, but the stalks and piping are absolutely amazing....The inside of my box looks like a weed recliner.....I am shooting for 2lbs plus this run for various reasons all of which I don't think would have a chance if it wasn't for the "mich" supplement...

Grow well

p.s. I apologize for all the double posts early on...

I think that worm castings are probably the best value for your money. Also for 15 dollars root organic sells a product that has fungi and bacteria. Bacteria is what mj likes best as it is an annual. Annuals prefer bacteria to fungi. Fungi fine, but dont forget bacteria teas and compost and worm castings to get them. Also place in soil. Aerate your teas with worm castings in them to stimulate the aerobic bacteria herd. That is the varitey you want. Aerobic. Add 1 tbsp of balcstrap unsulphered molassses to a gallon of RO water to feed the bacteria. Then aerate it for at least 24 hours with as much air as you can pump. You will have all the bacteria and fungi you want for a few startup dollars. I have my own wormxompost bin and am compost reg style too. I also by a product called super plant tonic by Blue Mountain Organic for 8 bucks off ebay. They add a lot of bacteria to this and other benes. It lasts a whole grow. Add a tbsp per gallon of tea. A lot of this would work great in a hydro reservoir.
