how to grow mushrooms the easy way

I thought coco had no nutrients in it? Like canna coco bricks?

Yeah, it has no nutrient value for plants, mushrooms are not plants.

Mushrooms will eat lignin and break down straw. I grow oyster mushrooms and they love consuming coir.

What type of coir should I use then?

So I use coco coir bricks in my substrate mix for mushrooms. I have refrained from adding much to this discussion though because I don’t grow using canndo’s jar method.

SWIM is doing canndos jar tek and they used coco coir. First cube picked was July 12 and they are still being harvested.

I just got 6 jars from midwest grow kits along with golden teachers from apex spores xant wait to noc em , if everything goes good I wanna do blue meanies in the tub

In case it helps any user who starts with this...

Its been 4 days since inoculating the jars with my syringe and cant seen anything yet...how long can it take to start fuzzing?

I believe that can all depend on your environment. What are your temps? You want the temps up towards 78°f, no higher than 84°.

keep misting or stop or reduce???

Keep misting, once a day should be good. All you want is to keep the fruit from cracking.


After you pick, spray a little more.

Use sphagnum peat

Pure coir prompts your casing to overlay or "tuft up". It doesnt promote those tendrils of mycelium to coarsely travel up through the casing. These sort of fingers are what the primordial start on.

Certainly, no casing works and using a very dilute mixture, say 10 or 15 percent coir works ok but much more sort of defeats the purpose of casing at all.


Further, this method does not work very well fruiting from all grain. Best you case with a nutrient poor mix.

But be sure you balance that ph. (Secret is that it will work even if you dont but the thing will contaminate earlier and have trouble growing through.

Looks very good! Pretty nice pin set, probably not too bad on the sides


Makes me a little nostalgic. They get downright pretty when they open up above the jar.


I trust you were patient enough to let that happen.

Ok, I'm confusing people. I originally said to use coir. So use coir and stick to the plan. The dilution factor is key. And the picture looks like it was done perfectly.

You should see something in a few days more at most.


If you dont then the spores were no good or your jars were too hot.

@canndo Awesome read man You ever watched any of home mycology's vid's on youtube? Guy walks his own path for sure..... Not knocking the guy but the throws the big FU to being sterile and seems to do well.......

Here is the thing, aside from isolation of strains, sterility is a crutch.

The point is to work with the environment, have it selective for your chosen species.

Exact ph, exact air flow, exact humidity and moisture. It is about encouraging your species to thrive and the others not to.

My tech just adjusts for the inevitable, things get contaminated. Let them, and continue with the units that arent.

Nature baby. You do the same in any pot grow.

I'm working with tomatoes. My area is heavily infested with soil born pathogens.

Should I solarize my soil? Or should I graft my heirlooms to root stock that is naturally resistant? This is not some nutzoid aversion to "chemicals". If you inhabit this place you likely enjoy "chemicals", it is strategy. Understanding of environment and adjusting for it.


Capitalize on the fact that all mycelium is highly resistant to contamination. The quicker you have full colonization the less you deal with competition.

And it is surrender, finally, to
The inevitable.


Thanks for your complement.

Second try using this tek. First try I did some things right, and a few mistakes, mainly with temperatures and using fine vermiculite . Made some adjustments , Temps were pretty good and I ended up six for six. All are producing on first flush, started about a month ago. I am an 68, never would have tried to grow mushrooms until I read this tek, what fun it has been learning about mushrooms and watching each stage. Not huge, but I am super happy, two strains, b+ and golden teacher, thanks Canndo.
