First timer: Was gifted a mixed mushroom package and want to use the stembutts to try and grow them
    #26992677 - 10/19/20 10:31 AM (3 years, 3 months ago)

Hi everyone, have been reading around here a lot as I was planning on buying a king oyster fruiting block to grow my favorites at home. My partner grabbed a mixed mushroom package and told me I could probably get started with growing stembutts! Not what I had been researching but sounds fun, and since I don’t want to let them sit in the fridge for too long I need your help to pull this together quick! I promise I’ll do more research once it gets going safely :smile:

(Edit: Maybe I wasn’t very clear with my question, I do apologize and will try to rephrase:
I heard you can grow mycelium from stembutts onto cardboard or coffeegrinds. What is the best method to do this?) I have king oyster, shiitake, and beech mushrooms.

How can I best start? I have loads of cardboard and a bit of coffeegrind. I can get straw/woodchips/pellets/sawdust after next weekend. I have no pressure cooker but a bit of knowledge about pasteurizing on the stove and I own a slowcooker. No possibility to make agar.

Bonus question: Once I have mycelium growing, what would be the best way to store part of it so I have some backup if my main grow goes sideway?

If you have fresh mushrooms and no way of making agar I don't know how you will get a culture. If you somehow get a culture you would want to make master slants to save the culture. But again you need a pressure cooker and agar.

You can buy spawn and make it easier but you really need to get at least a 23-quart pressure cooker...

Maybe I wasn’t very clear with my question and you misunderstood, I do apologize and will try to rephrase:
I heard you can grow mycelium from stembutts onto cardboard or coffeegrinds. What is the best method to do this? I have king oyster, shiitake, and beech mushrooms.

I don’t have time to order agar supplies and set all that up, by that time the mushrooms will be too far gone to do anything with it.
I know there is a high chance of contamination and fail, but please remember this was a gift and we are just newly discovering the world of mycology and are super excited to try something fun at home while we wait and learn and save up for “the correct way to do things.” For now we just want to try something basically free, fast, loose, and fun!

you can do cardboard or coffee. but neither are appropriate substitutes for agar. we are suggesting agar for a reason. it really is not hard to do at all

Once you have a culture you can grow them. But you must take a clean specimen from the inside of the mushroom and place it on agar 1st. That's why I said buy spawn but then you will still need a PC to sterilize the substrate unless you are going unsupplemented. It really does not sound like you are ready you need some sort of fruiting chamber if you are not fruiting outdoors. We can help you get to where you want to go but you need to decide what you are wanting to do.

It will never work with shiitake or beech, but try it with the kings for fun if you want, that's the only one out of those that has any chance of working, so give it a go!

Sorry I can't help you with a preferred write up, as I've never done it, but there's loads of YouTube videos and blog write-ups out there.  Good luck!

shitake and oyster where fresh and locally produced, but the beech mushroom where imported from china and took some more time to recover than the others...maybe also the culture is more spent, anyways the oyseters and shitake are growing really fast and nice

@el gordo

Did you even read what they were talking about or you said "NOT TRUE" just because?

sorry dont wanted to sound rude😇😇😇😇 u said it was impossible to do that with shitake and beech mush, just showing u some plates of shitake and beech mushroom done that way, cloned from the supermarket, hence my statement

Well, you did it on agar (which is the right way to do it). But the originator asks on cardboard or coffeegrinds.

@el gordo: your experiment looks very fun! It worked very well, especially the shiitake is surprisingly keeping up with the oyster. I think being locally grown and fresher makes all the difference for startup times :smile: I love seeing these pictures, thank you so much for posting these. Do you have plans to grow these out?

My king oyster and beech mushrooms are growing on the cardboard very well. They needed some time to get started but growth is rapid now and they are ready for another feeding of cardboard.

For anyone searching: I tried two methods (of course with cleaned supplies, area, hands, etc.)
1) boil long strips of cardboard, let it cool down, squeeze out the water and put mushroom pieces from the insides of the mushroom inbetween cardboard layers, roll up the cardboard and put it in ziplock-type bags. I didn’t quite close the baggie all the way to allow some air.
This method was the most unsuccessful, there is some growth but it is negligible so do not recommend this
2) I put long strips of cardboard into a strainer, boiled water and poured this over the cardboard. Let it cool and squeezed out excess water. I layered the mushroom bits with the cardboard and rolled it up, put it in a plastic bag that I tied a knot into, pocked some holes in the bag with a needle and covered with maskingtape.
This method worked much better, there is lots of growth. I think the cardboard staying a little dryer mattered a lot, as well as less air coming in to the bags by using the tape.

The mushroom are not getting many nutrients from the cardboard so the best growth will come from fresher mushrooms that have not been imported (just like el gordo noticed!). The reason to grow on cardboard with old stembuts is because it is very contamination resistant and not much will grow on it. Because of this you are giving the very weak mycelium a chance and time it needs to restart it’s growth. Coffegrinds for example are very prone to contamination and lots of things can get nutrients from it not just the mushrooms. If you where to try the exhausted mycelium on Coffeegrinds it would be difficult not to get mold but the cardboard will get the mycelium growing without competitors. Of course your mycelium will not be clean at all as the cardboard is very dirty, but it is a fun little project to witness.

- - - - - - - -

I am not sure why so many people here want to discourage experimenting and having some fun to people new to the hobby. Did they expect me to be hoping for a huge professional yield from cardboard? Seeing mycelium grow for the first time is very new and exciting to me, and I am enjoying myself with this experiment. I am also learning a lot, and there always seem to be more which I really enjoy.

What would be very useful to me from more experienced growers is information on how to do agar or grain spawn without a pressure cooker. I am completely willing to do agar, that is not the problem.
On english speaking forums it is not easy to find this information, mostly the threads I find end in being scolded that you can absolutely not grow mushrooms or do agar without a PC. The world is a big place (with a very old history) and pressure cookers are not an option everywhere in it the way it is in america. Some people (like me) also have chronic disabilities that make operating such things even more impossible even IF they could get one.
Some days it makes me very sad to know I can not ask advice without being told I will never succeed, and then I need to remind myself that mushroom cultivation has been a thing on this earth for a very long time, long before PC’’s and laminar flow hoods even existed. I understand that a PC has the highest probability of working clean and succes, but other parts of the world will just have to work with what is available to them. I have an old microwave and a big pot to steam in and those will have to be my tools going into this mushroom adventure :smile:

Apologies for any mistake in my tekst, english is not my first language and I am also sick this week. I am learning a lot and doing my best with what I can. I hope everyone and their loved ones are healthy in these times

It's pure science, it needs 121 deg.C to kill anything.

People before could not know that information and that is the reason most mushrooms were never cultivated before. The button mushroom that grows on compost was cultivated since 1600s, but that is probably due to properties of compost, it gives mushrooms a chance to outcompete.

You will not find cultivation of oysters, lion manes, etc. in old times.

I live in South Africa, there are only electric pressure cookers on the market which are useless as they cannot reach 15psi pressure. So I had to start saving and then pay even more money for delivery from Amazon.

I understand your frustration as I had the same, I watched many stupid videos on YouTube about cardboard etc, but it can only work on occasion. My advise is to start saving money right now and order it (usually Presto 23quart), there is no way around it.

Do it even if it takes a year to collect the money.

Just searched, first high pressure device (Steam Digester) was invented in 1679. So in theory since that time it was possible to sterilize, although I did not find any information about if it was actually used for that purpose.

Germ theory started to be understood only from 1850s with the work of Louis Pasteur (see the name!). So even if they could sterilize prior, nobody would understand why bother to do it.
