[Grow Tek]Growing Shiitake In Jars
« on: January 05, 2019, 09:02:48 pm »

My first time growing mushrooms in a jar. I had shiitake plugs leftover from my log(pics of that in my grow log), so I didnt want to waste them and decided to grow shiitake in jars. F%$k it. <3

I did the standard method. I will try to lay this out like a tek I guess? maybe it can help some folks out who havnt got the money for better techniques. Warning: My terminology is terrible. Nor am I a writer or amazing at speaking typing etc.. anyway on to the main topic.

Gather your supplies first, if you havnt got em. Jars, brown rice flour, vermiculite, pressure cooker, or big ass pot with a lid, still air container( I did not use one in this), and your medium of spores/cultures for inoculation.

For this I followed a video online.

5 mason jars, with a hole in the lid.
2 cups of vermiculite.
1 cup of brown rice flour.
1 cup of water.

I mixed the verm and the water first to get it moist. Mix nice and evenly for a couple of minutes. Add brown rice flour, and mix again for a couple minutes until verm is nice and evenly coated.

Pack the jars with the mixture and leave like a small amount of space to pack some fresh dry vermiculite on top of that, and then close the lid on top. Cover with foil when done.

This step you can use a pressure cooker if you have one. Im consistently broke for such items, and had to use a pot hence why I chose BRF + verm method. I just layered the bottom of the pot with jar lids, and aluminum foil until I had a nice layer for the jars to sit on top of without being submerged in water. Remember you only want to steam the shit out of these, not boil the jars, not that a little submerging wont hurt. It boils off rather quickly. So yea, dont submerge the jars. Close the lid on the pot and simmer/boil the water for 90 minutes.

Take the jars out and let them cool naturally to room temp before opening.

Get the still air box ready, and everything cleaned and sanitized with whatever you have. Assuming most people have some knowledge of this cleaning aspect. I did not have the money at the time to buy a container for the SAB so I just did the best I could with what I had. No air movement, some candles, and some high hopes.

I opened each jar one by one, and placed in each, 3 wooden plugs of shiitake spores. Some of them even had colonized grains attached to the plugs, very exciting aye. I did not waste time, and was very careful as I did this.  I initially did not push the plugs down far enough into the BRF+verm and was questioning whether this was going to work or not, but no worries it found its way. BUT if you do this, try to push it down far enough lol.

To cover my holes, I did not have anything I truly needed so I did alternative I guess? I cut the ends off q-tips with some of the stick attached, and stuffed them into the holes in the lids. I figured some air exchange wouldnt hurt, and the q-tip is dense and packed tightly in the hole to protect from 'some' contamination.

All done at this point. I threw my jars into a small shoe box that fit perfectly, and placed it on my shelf. Its pretty damn humid down here in Ga, so humidity isnt a problem right now lol. Temps stay between 68-80F in here so its not too bad.

My jars have been colonizing for over a week now so they are pretty far along but that is the only good pic I have of this method so far.

Remember I am learning as this goes along, as Ive never done this before. Fruiting will be a new experience and any advice and tips will be appreciate. More pics will be posted as I update with more information!!

Peace.

That is awesome darkpines congrats!  8) you probably already read all this but:
Quote
Shiitake grow in groups on the decaying wood of deciduous trees, particularly shii, chestnut, oak, maple, beech, sweetgum, poplar, hornbeam, ironwood, mulberry, and chinquapin (Castanopsis spp.).
The Japanese cultivated the mushroom by cutting shii trees with axes and placing the logs by trees that were already growing shiitake or contained shiitake spores. -wiki

https://freshcapmushrooms.com/learn/growing-shiitake-mushrooms/ some info there

so after it colonizes completely, (because the BRF would contam if it doesn't)
you might could spawn that to something like sawdust or woodchips..
maybe you could keep a continuous growing supply of mycelium.

Thanks for the links! I def appreciate that!

So, after reading this and thinking, I was pondering the monotub idea after my cakes brown? I can mix up a substrate I guess with some sawdust and things. I dont have a lot to work with, and my jars are completely colonized now, besides one at 75%.

Some of the threads I was reading before though, a few people mention growing in jars and opting out of sawdust because it slowed down mycelium growth I think? Something was wrong with it, anyway. Idk. LOL

Now that you sent me those links, I kind of want to trash the idea of fruiting cakes, and just bulk fruit these somehow? Keep in mind this is my first time. I might stick to my jar idea and just see what happens? I can always start over, or carry on this mycelium I have now. I mean, I only have 5 half pint jars fucking packed full of it now LOL

Any other suggestions maybe?

ive never grown shiitake either, though it would be a fun project..
Maybe you could make some more dowels to inoculate more logs?
I'd be interested in some if you ever get enough going to spare :)
Maybe find one of the trees listed, cut off branches, turn into logs.
youtube probably has some info. Here is another link looks good..
https://cpb-us-e1.wpmucdn.com/blogs.cornell.edu/dist/d/958/files/2014/03/Shiitake-BMP-3-11-1osfnxs.pdf

i wonder if small branches could be turned into dowels?? idk,
One picture in that pdf looks like they used a small metal pipe
to make dowel size sawdust sections, that what it looks like.

Not a bad idea. Id prefer not to cut down any trees around here because the only good ones are live oaks and I want to say those are protected against cutting. There might be some better ones around here but yea unless I can import some logs from elsewhere like I have been, I might find another way to do this. I can get plenty of saw dust and possibly some wood chips too.

Reading paul stamets mycelium running is filling me with SO many ideas.... :o

heyyy good-looking! ;)   ;D


ive never done shiitakes before, so idk the best way to fruit
but pretty sure shiitakes gonna need some wood

i would soak woodchips for 3-5 days
hardwood, hickory or alder chips for bbq smoking are usually easy to find, but dont use fruits like apple or cherry
gotta hydrate the chips
and id use rainwater, if available, but tap water should be fine
id toss a lil gypsum in
after a few days soaking n woodchips mostly sink, boil these for a bit, ~45 mins
strain n let chips steam off & cool overnight

now you have lots of options, idk which is best, for shiitakes, or for you
gotta figure out how you want to get the spawn to colonize wood, without contaminating over time
youll probably want to end with a cake or block of some sort

i think they do well coming off the sides of things, not just the top, which is why cakes/block are good
so i think some sort of large bag method would be best
you could try like xl spawn bags, idk if youre set up for all that.
mix with some grains or bran, PC for a while, dump some spawn in, seal, wait till colonized then cut the bag open, poke some holes in the side,
or just remove the whole block from the bag once colonized, enter fruiting conditions

you could maybe just pasteurize the chips, then load up heavy duty garbage bags with chips & colonized cakes
you can do oyster on straw this way, but oysters move pretty fast on straw and are fairly resistant to contams.
wood is pretty contam resistant as well, but slow to colonize, vile things might catch up
mostly worried about your colonized spawn turning green once exposed
idk how clean fresh garbage bags are, what kind of "clean room" environment you would have to load them in, how vigorous your shiitakes are
so this method could be risky business

i know i have seen large garbage-bag -sized bags fruiting... not sure what kind of bags these are or how to do it in a kitchen,
but thats what i would try to do

you could also try a monotub type setup
they will fruit from the top only, idk how they would like that
you could poke holes in the side.... that might get you some more weight on the side, but then your totes likely ruined for future use
or you could maybe try small bins, and once colonized, pop the whole mat out as block

ive been using jars for years, but i just received my first spawn bags and other new supplies, feels like i just leveled up!
so im about to start some similar projects!
best of luck, keep us posted!

Much appreciated information!

My jars contain inoculated dowels from which the spores grew from in the jar. Each jar contains 3 dowells. I did consider this more afterwards too, and have already been planning on my next shiitake jar grow. I will be doing monotubs in the future for these, and I will be doing some outdoor bulk growing as well.

In fact if anyone has some good information on growing outdoor shiitake with cakes to bulk, I will read it!!

But my original idea came from this thread here https://www.shroomery.org/forums/showflat.php/Number/11897262/fpart/1/vc/1
Very cool stuff!! Thanks again! <3
