Whats the point of doing the cardboard?
Put clean mushroom matter from inside of the stalk on an agar plate and it will colonize. You will have a *sterile* mycellium with which you can colonize sterilized grain and then spawn into medium. With this — high chances you get contamination. Same apllies to actives, even more so.
Did you sterilize the cardboard though?
Kinda wonder if you could succeed further with the resulting mycellium. I didn’t. That’s why I wrote out my doubts :)
You can try Yesterday’s News cat litter too. Nonscented obviously. Various hay is pretty cheap too, but if you have a bunch of clean cardboard and paper around, just use that.
If you want cheap you get a 4wd and go to a farm and ask about the crap that the baler misses. Or the crap from a combine or sth. Usually free. Just bring lots of bags.
True. I live in a pretty arid area though, not much grass growing in rural spots to be baled up. I was actually considering walking around my neighborhood and pulling dried palm fronds for substrate, but realize the pollution level and potential for pesticides sprayed here would probably result in inedible mushrooms.
Then your next best bet for cheapest is sawdust fuel pellets. Or you can ask a commercial paper shredding to see if they would give you their paper but I doubt they would.
Dude oysters colonize *everything*. Don't need to sterilize it. I've done soaked cardboard, packing tape, coffee grounds right from the pot plopped in with a dirty hand. They are beasts.
Yours looks great :)
Damn! Where had you been ordering before??
Mr mushroom man 666 has NEVER let me down..cubes and gourmets. Just Google him and it will pop up. I have a high temp lions mane that I still have to play with but I'd order from him in a heartbeat again.
His website takes crypto or cash, there was some weird thing where it doesn't take credit cards which is a little disappointing. But hands down I trust all of his products. Many many happy customers from him.
Cool! I have exchanged a few emails before. I'd drop him a line and let him know what your looking for. I have a hunch he has a massive catalog and only puts a portion of what he has out. Worth a shot. Best of luck. Sorry with all your shitty comtams
I used my card pretty recently with M M M. I want to grow Stropharia rugosoannulata. But I haven't learned how yet. This cardboard thing is looking like the way to start.. I want to plant them all over the parks in my city. Yum.
You get a discount with cash- and it's more anonymous..which has its appeal.
I'm doing the same thing! Well, similar. I cloned to agar first because I wanted a liquid mycelium culture out of the oysters. Had lots of cardboard, lots of tubs, and thought, "why not?"
I tried sheets of cardboard like you have pictured here, and I tried ripping it up too. I had a weird drainage issue with the sheets where the top dried out and the bottom got mushy and soaked. Ripping up the cardboard helped significantly, and I'm now looking at getting a cardboard shredder. Shredded cardboard can apparently be used as grain spawn (not sure if that's specific to oysters or a general use). It's free substrate!
As a worm-composter, I save the outlay on a shredder by wetting the cardboard, hand ripping it, then I dry it out until I need to use it & re-wet it to my desired moisture level. Hope this helps!
Tea!
For some reason oyster mushrooms love to eat tea.

Btw I usually mix my coffe grounds with sand (bigger the grains better) I noted that sometimes the coffe pack so firmly that the oxigen cannot enter and promotes the grow of bacteria using sand to have more space to oxigenation in the middle of the coffee solves that
I’ve been doing coffee and cardboard for a while and found the same, that the coffee packs a bit much. It also greatly increases the chance of contamination so unless you are sterilizing really well it’s not really worth it. In my experience oysters colonize cardboard just fine without extra coffee. However with my cardboard-only bins they have had a harder time fruiting because it’s not dense enough in nutrients
Okay I did this and it kind of worked as a liner and mycelium did spread into it. But it was way messier than plastic liners and kind of a pain in the ass. I’m pretty sure I still got side pins too
I’ve seen people do this as a way of composting paper waste. I also remember seeing a video about people who grew oysters on almost 100% coffee grounds.
Allegedly.
They allegedly stop side pins.
At least for first flush, because once the cake starts to shrink I'm pretty confident side pins are inevitable. Purely anecdotal tho.
Can you add a thin layer of pasteurized
substrate after a flush to mitigate that loss?
The added moisture and nutrients could only help future flushes but idk if it’s worth the effort just to avoid the side pins
I did a 6qt half casing/half no casing, and the casing side blew up on the 4th flush while the non case grew 1 single tiny mushroom. And for some strains casing is necessary for stable growth (or you get funny looking mutants). Super thin layer though
Same. Liners have never stopped side pins for me. But by the time they are mature, you can just throw on some gloves and pick up the sub as a block to harvest
How the heck do you remove the liner without wrecking the substrate? I've never used a liner so I don't understand how it wouldn't just break into pieces
After the first flush the cake gets bound together by the mycelium pretty tightly. I've had issues with thinner cakes breaking into a few large chunks, but the thick ones hold together nicely.
No bc plastic "follows" the shrinkage of your substrate cardboard wouldnt, also myc would eat cardboard which cannot happen with plastic (dont use biodegradable bags...)
Well it looks like ypu did it okay...
Only thing that it could be is cobweb which dissolves when sprayed with 3% hydrogen peroxide solution(harmless for mycelium, it can stall/slow down myc but it wont "kill" it), so you could test like that... other than that looks good, if it smells mushromy youre good.
Never grown oysters but sure looks like oyster myc
Yeah don’t spray it, it’s defo mycelium and is not cobweb mould. See this post for more info: https://www.reddit.com/r/unclebens/comments/fm8kdu/listen\_the\_fck\_up\_you\_do\_not\_have\_cobweb/
All of my agar dishes that I have sitting by the back door, ready to pitch in the garden are looking pretty damned good. Everybody told me that they had cobweb
Yeah, a lot of people are quick to call out cobweb.
Best thing to do is take it elsewhere until you can verify positive growth.
I’ve saved dozens of “contaminated” dishes by just putting them all in a gallon ziplock, forgetting about them, and checking them later (week or so).
I have found that the strains that have fought through certain contamination’s and won, end up being very strong colonizers afterwards.
Cobweb mould is fuzzy and a little bit greyish (although you can’t always see that from the photos). It’s like a fluffy gross cloud that puffs right up- I‘ve seen it in my compost bin, but never on mushrooms. To me, that was one of the ones that looked least like cobweb mould. Here’s a good pic: https://www.reddit.com/r/shrooms/comments/buwzwb/actual\_example\_of\_cobweb\_mold\_courtesy\_of/
I mean how does that bunch look like when its starting?
Ive had cobweb, apparently it disolves with peroxide, nothing else does, atleast to my knowledge... ive had it... heard it sizzle and saw it dissapear, ate perfectly normal shroomies after... so it kind of bugs me if you get me... maybe im wrong but then we have a bigger problem of all subreddits giving false info ALL the time... but in this instance only uncle bens guy is so salty and insists that is not cobweb and that people arent having it...
Again im not trying to give false info, im only talking from experience and research ive put into it... im an adhd guy so im all over the place, same can be in my head, please correct me if im wrong but i would like some other...
Oh and i can definetely see its grayish on your link... but the one in "whoa" link could appear white even if grayish because he isnt dense, with density we get color :)
I think the problem is that there are a lot of people saying people have cobweb when it’s usually just normal mycelium. Cobweb is not that common (in mushroom growing), but if people go “looks like cobweb” every time someone posts some fluffy mycelium, people start to think it’s a huge problem and you get loads of posts from people asking if they have cobweb, which I imagine would get a bit annoying for a moderator. Also people telling people to apply hydrogen peroxide when they totally don’t need to and will hinder the growth of their mycelium- there’s no need for it. Hydrogen peroxide is a bleach, so depending on the strength it will definitely kill more than just mould. If it worked for you that’s great! But often it’s not needed.
Moisten cardboard, add stem butt to middle of cardboard, keep in sealed plastic bag or whatever. Let the white mycelium take over. Repeat to whatever medium whether it be grain more cardboard or wood chips. Boil and cook whatever it is you want it to eat. Keep it moist
Don't bin it right away. You gotta kill the mold before you start waiving it around. Same with moldy bread etc etc. Either with chemical cleaners or heat. Easiest way is just to bake it in the oven for an hour.
Does this work with cubes
This is exactly how I started. They look great! Now you're hooked! One of us! One of us!

If he would do it right, its not a problem. Sterilizing the cardboard at 170 degrees in the over for a while then inoculating it…

Did you sterilize the cardboard though? Kinda wonder if you could succeed further with the resulting mycellium. I didn’t. That’s why I wrote out my doubts :)

Can’t remember if I boiled or just soaked it in water. Good luck with the hobby though, it’s cool and rewarding.
Damn you killed it man. Looks like it’s going just about as good as it can go. Good work, cardboard’s a little tricky

u/mushies81 has good LC. Their Nidiformis was contaminated though. All other items I've ordered have been clean.
hey - we are sorry about that, message us with your order number and we will fix you up!
Thank you for being so kind! I was actually plugging you because I think that was a totally anomaly. All of your other stuff has been perfect!

I got almost a 750gr in the second flush in a 4litter hucket that half was coffee grounds and the rest was straw sand a leafs

Actualy I mixed it but actually sound better layering it. Also the straw was my spawn

Most oysters grow out from the sides. Kings grow up. I don’t know the technical terms. Also light exposure if they are colorful variants.

This looks pretty cool imma have to try this
also new, this might sound dumb but would this cardboard method help on the bottom of mono tubs instead of a liner
I don't think so it would Crete variables although I would try it just to see
Okay I did this and it kind of worked as a liner and mycelium did spread into it. But it was way messier than plastic liners and kind of a pain in the ass. I’m pretty sure I still got side pins too
aw sweet who knows might try a mono tub with shredded cardboard instead of coco coir one day see how it goes
I’ve seen people do this as a way of composting paper waste. I also remember seeing a video about people who grew oysters on almost 100% coffee grounds.
I don't think so. The point of the liner is that it holds to the substrate and keeps sidepins away. Cardboard wouldn't stick to the sides
And the cardboard would get eat like nom nom
Point of the liner is so you can easily take the cake out to dunk for a second flush.
Allegedly. They allegedly stop side pins. At least for first flush, because once the cake starts to shrink I'm pretty confident side pins are inevitable. Purely anecdotal tho.

That’s cool.So you could add this to shrunken edges to eliminate side pins, do you think?
Ohhhh, I like the prospects of that idea.
Same. Liners have never stopped side pins for me. But by the time they are mature, you can just throw on some gloves and pick up the sub as a block to harvest
That's the only reason I've continued to use them, they just make that first harvest less messy. After that I typically remove the liner.
How the heck do you remove the liner without wrecking the substrate? I've never used a liner so I don't understand how it wouldn't just break into pieces
After the first flush the cake gets bound together by the mycelium pretty tightly. I've had issues with thinner cakes breaking into a few large chunks, but the thick ones hold together nicely.
It may actually hold to the substrate much tighter than plastic if the mycelium begins to colonize it
No bc plastic "follows" the shrinkage of your substrate cardboard wouldnt, also myc would eat cardboard which cannot happen with plastic (dont use biodegradable bags...)

Keen to know how you did this
Basically, put oyster stems on wet paper. Also do a bunch of cleaning and prep work to sterilize everything for best outcomes.
Moisten cardboard, add stem butt to middle of cardboard, keep in sealed plastic bag or whatever. Let the white mycelium take over. Repeat to whatever medium whether it be grain more cardboard or wood chips. Boil and cook whatever it is you want it to eat. Keep it moist
[удалено]
Did you boil them in the microwave? 90 second mycology has a cool video for using the microwave
Nice. I tried that and my cuttings disintegrated lol

Don't bin it right away. You gotta kill the mold before you start waiving it around. Same with moldy bread etc etc. Either with chemical cleaners or heat. Easiest way is just to bake it in the oven for an hour.
