- เผยแพร่เมื่อ 17 ต.ค. 2024
- Learn how to grow mushrooms! Most gourmet mushrooms grow on supplemented sawdust fruiting blocks that have been fully sterilized. The fruiting block recipe is as follows:
Per 5 lb Fruiting Block:
5 Cups Hardwood Pellets
1.4 Liters Water
1-1/4 Cups Wheat Bran
Mix ingredients, add to grow bag and sterilize for 2.5 hours at 15 PSI.

Don't put the jiggler on until your canner has steamed for a full 10 min, then add the jiggler and watch for the pressure reaches 15lbs. Adjust the heat (lower slightly if pressure climbs over 15 lbs) then time for 90 min.
Thank you!
No
@@pianchick yes… maybe not every time but it’s good practice.
@@natewheeler1806 Why? I've never had to do this
This is helpful and timely. Thanks for sharing. One note, taken from my experience.. venting of the PC is an important step, it helps to purge the air and raise the internal operating temperatures during the heating cycle. It also makes for a much quieter heating cycle, particularly with the wobble weight type cookers like the Presto. Cheers.
Thank you, so much for detailed instruction and tips. I just got my first flash of Shiitake I grew on saw dust and brown rice cakes in vitro. After finding your video I decided to go the next step with blocks. They have been inoculated with rye grain spawn on 2/3/19 and everything looks great!
how did it went?
we are growing them in deep mulch, i really hope they work. I love mushrooms. Im growing wine caps and blue oyster mushrooms
Your videos provide a lot of value. Thank you for sharing and your generous spirit. 🍄💖
I followed your tips and now I have four jars of mushroom spawns (two white oyster mushrooms, two pink oyster mushrooms) ready. I acquired som sawdust, plus wood shavings and will attempt to make my first fruiting block
Here a legend was born not a famous legend but a mushroom legend.
You did not mention if you used rain water, spring water or treated municipal water. I live in a town that treats our water with chlorine, so I can always fill a large container with water and leave it in the sun to help evacuate the chlorine or I can catch rain water the same way. Thanks for the videos and information.
Did not know Aaron Rodgers was a mushroom farmer. Thanks for the video!
What do you think he does between games?. That's right Mushroom blocks from Saw Dust.
What are you using for the filter sleeve? Does it need to be something specific to hold up during sterilization?
Interested in this also
I like that filter sleeve ! Brilliant ! 🍄
Will this work without the extra filter sleeve inside during pressure cook?
Also does Turkey tail need a sterilized block?
Usually if you let it cool naturally it "seals" itself. Also, 3 quarts should suffice for up to 3 hours. My question is, you put them right up to the edge of the canner. I've had bags break that way but you never have that happen?
Dude your hair is perfect!
Hey Tony, love your videos man. I followed this recipe to a tee but I had some problems with bacterial contamination due to excess water. I believe it should be 5 HEAPING cups of HWFP to end up with 5lb block. What do you think? Oysters were fine but some other picky strains did not like the excess water. All the best man! Keep making awesome videos
always squeeze your substrate to check for field capacity.. if you squeeze and a few drops come out, it's perfect. if none comes out, add more.. if alot comes out, you have too much
Hi Tony, thanks for all your great videos (and for looking good for all of us ;)). I found wood pellets 80% beech and 20% spruce - will this work? I heard spruce resin stopps shrooms from growing...?
Thanks for these videos, they're really helpful!
Thanks for the video, very informative. Where can I buy oyster spawn?
Love there products and videos ! Started growing a few months back to make tinctures. I’m hooked
Shot every time Tony says "I like to."
Good tutorial. See yall on the facebook group.
You could have a Shot every time he says "Go ahead", but you wouldn't make it to the end of the video.
Bad idea. I do not recommend this. I have a horrible hangover now.
How do I know if my pressure cooker is running low? Will there be a change in the pressure itself? Also how do I add more water? Does that mean turning it off adding more water and then allowing the pressure to build back up again? Sorry, I’m a newbie🍄🍄🍄
thanks for the most user friendly, informative videos online hands down. question: does pasteurization in this case simply mean your adding hot water? i thought it involved letting the sub mix sit in that hot water for many hours?
Woods substrate takes sterilization. Couple hours at 250f usually in a pressure cooker
Is that sawdust only and dont have any added subatrate??
Thanks for this helpful video. Our pressure cookers are rated max working pressure is under 12 psi in UK. I bought one just as I can’t afford a good All American one yet. How long is long enough in this cooker do you think? I’ve a horrible feeling it’ll run out of water before the optimal time in there.
I have been following all your lessons and good ,now do you prepare the seed of mushroom ? preparation for what to plant ?
do they need to be pellets? or can you use straight saw dust. there is a harswood mill near me where i could get a crap tonne of the stuff.
saw dust will work too
Did you heat seal those bags before they went into the pressure canner, or were they left open? Were they sealed after? Without a laminar flow hood, what would you recommend for closing the bag, and also what would you recommend for inoculation? Self-healing port a must?
Is it a good idea to bring your PC to a boil and let it vent with the lid on for a good 10 minutes? I've read that unless you expel all of the free air inside the PC, because of partial pressures, you won't actually reach the temps necessary for sterilization at 15psig.
Yeah it would have been helpful to mention venting. 100% need to vent according to your PC instruction manual
Is it possible to mix hydrated lime into the water, similar to the process you used with the straw for oyster mushrooms if you don't have access to a pressure cooker?
That would pasteurize it, but not sterilize it. For most oyster mushrooms that would be good enough but especially for Shiitake the substrate needs to be fully sterilized.
hydrated lime works fine for oysters let it soak for 12-18 hours. Soap also works.
Would magic mushrooms be able to grow on this medium ?
Can you seal the bag with heat sealer befor PC-ing it?
it won't sterilize properly if you seal it, even with the filter patch
Do I need to use distilled water or is sink water ok. Will one cause contamination?
Great video, clear instructions with some tips you don't see many other places! One thought, as the PC is sterilised after 2.5 hours, couldn't you just put one filter patch over the air intake on the PC as it cools?
Good point! Actually since this video I haven't been using the filter sleeve and things have been going just fine.. no contamination.
I tried doing that my first few runs, as soon as the pressure hit 0 and the release valve dropped, I put micropore tape over the rocker hole. All of my bags blew out until I quit doing that.
Great vid as always… what size pressure canner is that? Any recommendations on where to pick one up?
Is Coco lumber saw dust good for substrate? I'm fr the Philippines.
Can you explain why so much substrate is used for making mushroom blocks or when growing in a monotub?
Why if the mushrooms are only growing from a handful of points on the block, why is some much needed?
Hey Sir. Are you using hardwood pellets for a pellet stove, or are you using ones for a smoker that are food grade, or? Also, any kind of wood better than another? Thanks!
Wood pellets don't need to be sterilized. At most you can pasteurize them and they'll be fine, even with the wheat bran.
Great video thanks so much! If using aspen woodchips for 5lb bags instead of pellets how much would you use?
Hi Tony, do you sell grow bags? If you don't, please tell me where to buy them. Thank you.
Ahh a good ol presto cooker! That s what I use and it's why I call it ol faithful :) great video!
Yup! Last for a long time too!
@@FreshCapMushrooms What size pressure cooker is that? Great video!
Could I not do the pressure cooker part by dumping boiling water into the wood pellets and the wheat bran when I'm mixing it essentially I've seen people do that with other substrates Like Straw woodchips excetera if you happened not to have a pressure cooker
Is it true you should not use tap/chlorinated water? To wet the pellets?
Can you microwave the "blocks" for 20mins to kill off everything inside instead of using a pressure cooker?
Do you seal the bags at any point?
if you grow in your back, ie you sterilize a substrate bag, and then transfer grain spawn to it, you would do this in a still air box and then seal the bag.. then after you allow the mycelium to colonize, you'll cut the bag open to fruit it, and place it in high humidity.. at that point the humidity and air exchange will make it start
is this substrate good for champignons? i'm doing a trial with some champignons leftover from cleaning of last day of cooking... Same content, but all done at a smaller scale (a small plastic container with all tape around but with a transparent lid)
Is that just pellets for smoking food or heating pellet stove?
Hi here in the UK we usually pc at 10psi , is this ok for this job also? Or does it need to be 15psi no matter where in the world you are
Hi Tony thanks for your helpful videos on mushroom growing. Would it be be ok to use oak wood sawdust which hasn't been compressesd into pellets? And apply the same recipe for everything else? Many thanks
Yes
Just a thought in those quantities it may be a good idea to invest in a cheap electric concrete mixer. It will save a lot of wear and tear on your arms.
So I work at a sawmill and our sawdust is like literally dust. More like the bran consistency honestly. Can I use it for anything? Red oak and white oak mainly.
Great video mate, could you tell us what sawdust among Jarrah, Pine or Red gum works better for Shiitake ? Cheers
Every video for sawdust actually uses the pellets. Can we use actual sawdust and would the amounts change if so?
Great Info mate I will try on my mushroom farm.
where do you get these filters for the bags?
Love tonys vibe you straight up know this fuckin gangster making loads of cubs
I enjoy your videos, and will be using this recipe soon.
Why do you switch between US measurements and metric?
Thanks!
I love your vids, they're the best on the "net". The one thing I can't find are any filter patches. How did you get these nice square ones that fit perfectly? Would grow cover for a garden work instead? Thanks..
you can buy the bags with filter patch on amazon
Hi Tony! I am from Brazil and I can not understand the measurements that you used of pellets and wheat bran, which would be in cup .... here we use Kg (kilograms) I'm sorry for my ignorance, but could you convert those amounts into Lb or kg?
gregory Gegembauer generally it’s a ratio of 40 lbs of bran or soybean hulls and 40 lbs of sawdust and 50 liters of water it’s called a masters mix
Divide pounds by 2.2 to convert to kg
Where do you get the filter sleeve? Can I use a pressure cooker thing used for canning to sterilize the bag?
Yes, that's what he was using, just a big canner.
Great video my man! Your right up my alley with the way you teach🙏🏽 Thank you for putting me at ease when I needed it most. How much spawn do to each 5lb bag?
Cosmic Healing glad you like it! I usually put about 1 quart of spawn per bag ( 0.5 lbs)
can I fruit mushrooms from grains without any additional substrate?!
I’m growing golden oyster mushrooms. My can was fully colonized when I brought it out into my fruiting chamber. It’s getting between 85 and 95% humidity, 75 to 80° and enough light. It’s been eight days I haven’t seen a thing start yet. Am I just being impatient? This is my first time.
It's possible to cold pasteurize (lime) this recipe? Cold pasteurize sawdust?
Question! Could you seal the mushroom bags prior to sterilization? maybe in a food sealer? I understand this would be a little counterproductive because they have to be opened for innoculation. Would tying them up help reduce contams?
they would explode. When you do canning you have to put the ring on over the lid but not tight as the steam inside the glass jar has to come out. When it cools it sucks the lid on and they pop. The same with the plastic bags. If they are sealed when cooked they may puff up and explode.
It's possible to make a cold pasteurization with sawdust, for shimejis cultivation?
hello all, 3 weeks ago i made some oyster mushrooms blocks, i used only and only pine wood pellets, i wanted to try only with pine wood . and this mornig i had a nice surprise......, so for whom is asking if u can use pine wood pellets, they worked fine for me.
have not grown my own...always foraged...your video interests me....how many types of mushrooms can be done this way?
where can i buy that filter sleeve?
At what point do you mix in the mushroom spawn? Do you mix it in when you mix in the soy bean hulls? And then sterilize the block with the spawn in it?
You mix it in (inoculate) after it has been sterilized. The process of sterilizing it would kill the spawn.
Thanks for sharing. Do you think it´s possible to use wood shaving instead of sawdust?
what if i dont have a pressure canner ?
What is your cost to make a block of substrate and what is your yield per block of substrate? And what is the average price per pound of product you get?
NoYezz oyster shitake sell for 6 to 12 lb idk cost
@@marlonsmith713 I just bought some oysters for 399 lb! Very nice specimens that I'm going to actually I already started making prints for liquid culture. I don't know if I should make great big blocks to grow these or a couple of little 5 pounders which to me is pretty big anyway. Any clues?
Can you make a video on mushroom house. Can you show us the outside and inside of the mushroom room.
I use the masters mix. I just put it in a Pot pour boiling water, mix it wait for it to cool then mix in the Spawn. That’s it. No contamination. Also have used aspen pet bedding with great results.
Really? How have you not gotten any contamination? I accidentally ordered masters mix instead of hardwood pellets and am not sure what to do once it arrives I'm not sure if I can sterilize it affectively. I ordered mushrooms bags and grain spawn aswell btw so I was planning on just hydrating substrate with boiling water then adding into bag (maybe pressure sterilizing) and then let it cool, open bag add grain spawn and then seal with ziptie.
Btw when its cooling down isnt the bag releasing hot air not sucking it in ?
I've heard that you can increase yields by adding gypsum to the substrate, but haven't seen any professional growers using that method. Have you any idea, why?
Gypsum is usually only used in the grain spawn, helps to keep the kernels from clumping up. At least, thats what i've seen from some other youtube videos. I only put it in my grain spawn.
Its true.the legendary RR highly suggests it on the Shroomery
On Paul Stamet's Growing Medicinal and Gourmet Mushroom / Peter McCoy's Radical Mycology books, they both list Gypsum in their nutrified sawdust block recipe. I'd then say it is useful, though I also saw people in forum mentioned they tried with/without and it was not a big difference. So yeah.. I guess you have to try and see by yourself! I do it with gypsum.
I am in France, and can't find anywhere Hardwood pellets. Locally they are all softwood from coniferous trees (some kind of pine family). Do you think it would work? otherwise any other alternative (straw/vermiculite/coco coir) that could recommend?
Will oat bran work for pink oysters? I read once online that it was fine but just more expensive then other brans so that’s why people tend to use wheat? Someone please let me know!
I hope you can help me. I bought Mycelium and I brake and put it in a box with moist and steriliesed sawdust, but the Mycelium is growing very slowly. It is there by 1 April: can you give and any tip?
Do you have a video on how to inoculate your bag?
Very informative and straight forward video
this is what i have been looking for thanks
Mixing imperial and metric units in recipe 😉
Great video though, very informative!
Hello Toni, How many time you recommend to sterilize empty petri dishes? 45min like the agar could be enough? Thanks in advanced
15-20 mins @ 15psi....along with your agar media.
Would is be possible to steralise first, then mix the fruiting block?
I don't have a pressure vessel- but its easy enough to whack the dry ingredients in the oven for a bit.
No
Hey Tony - I`m in the middle of my first attempt following these instructions with Lions Mane and Italian Oyster, 4 weeks into colonizing now. The moisture inside the bags seem excessive, water droplets on the top as well as yellow liquid at the bottom of the Lions Mane bags as well as Lions Mane fruit trying to fruit prematurely. Without a flow hood, do you have any recommendations on getting ideal humidity within the spawn bags when inoculating as well as what I should do at this point with my lions mane situation?
If I have pure sawdust could I simply mix boiling water in the wood and bran and wait to cool to make the blocks?
yep
I am new to mushroom growing but I am having success with oyster mushrooms on straw following your video, but Im trying my hand at pasteurizing my own grain. I have watched your videos on this but my problem is that my bags expand and get more moisture in them. I stuff rags around the bags to fill all the voids. What am I doing wrong becouse I want to pasteurize sawdust blocks for lions mane and I dont want the same issue to happen.
You ever use gypsum in these types of fruiting blocks ?
Question, about 20 days ago I introduced lions mane grain spawn to coir sub in a grow bag. It seems to be growing healthily but it’s growing very slowly. Can I shake my fruiting block bags like I shake my grain spawn jars in order to encourage growth?
Hey man thanks for the knowledge. I’m getting ready to copy this, what number filter do you use and what material do you use for the filter sleeve ?
This work for cubensis right???
How do you determine your percentages tho? You want 60% water prolly... idk let's say im shooting for 5lb blocks ... so I take .6 times 5 to see how much water goes into a 5lb block?
Can you grow them in a bucket rather then a bag?
Hi, I'd like to try bag cultivation of shiitake. Will this recipe work with shiitake, are there any other required aditives? Best regards and thank you for the information on your channel, it's really good stuff.
Yes it should!

Hi, thanks for the video first of all. All your videos are very helpful. I have a few questions.
I was wondering if you knew what type of tree the hardwood pellets are made from? Do you think it matters?
I have researched and found out that shiitake grow naturally on timber from the family of trees that include beech etc
I have access to a lot of eucalyptus wood chip and was thinking of using that as beech doesn’t grow in my area. Do you have an idea if this would work and if the mushrooms would be healthy to eat? I’m a bit concerned that some of the toxic chemicals in eucalyptus might not make it such a good idea.
Is there a preferred wood? Traeger has oak, ash, hickory, mesquite, apple...and the list goes on, for their hardwood pellets.
I am not an expert at all and am quoting from Paul Stamets "Shiitake will fruit on a wide variety of deciduous wood so it's a great mushroom for first-time cultivators...Thick-barked hardwoods like oak are the most preferable species to inoculate. Other suitable hardwoods include sweetgum, ash, chestnut, hornbeam, ironwood and hickory. "Scrub" hardwoods like alder, beech and birch will typically work fine, however the logs inoculated may not fruit as many years as oak. Poplar, cottonwood, and willow are suitable but tend to break down very quickly as well. There have also been reports of Shiitakes successfully fruiting on koa and on eucalyptus logs." I hope this has not stepped on any ones toes and is helpful.
Michael Vanecek You are looking in the BBQ smoker section. Get the hardwood pellets for home heating (pellet stoves) those are about $5 for 40 lbs. Save the mesquite for the ribs.
I just noticed fly larvae in one of my mushroom blocks :( how do you control the pests?
It definitely happens once and a while, especially if fruiting outside.... hard to avoid entirely, best way to fight it is just general cleanliness
@@FreshCapMushrooms also BT larvae killer (bacteria that only kills insects but not plants or animals) per RogerRabbit's suggestion
I know oyster mushroom grows better in straw, but have you tried to grow them in sawdust? thanks
