- This video demonstrates the inoculation method I use to grow a variety of mushrooms, including Lions Mane, Tree Oyster, Golden Reishi, Bears Head Tooth, Turkey Tail, and Garden Oyster.
The hardwood pellets are simply hydrated with cold water, and then inoculated with grain spawn. I use no heat or chemical treatment on the pellets.
Go to my educational website at coldmushrooms.w... for more information and pictures.
2017 Edit: Checkout this video { • Growing mushrooms as a... } showing mushrooms grown using this method, except with smaller 10 and 20 lb. bags. Also check out my commercial website at www.organicturk...
Music is a Vivaldi concerto for 2 mandolins in G major.
Hey please create next video of this project. Please let us know how was the result using hardwood pellet with cold water.
Go to my website at coldmushrooms.weebly.com to see the results and learn more about it. Every mushroom on that site and in the flickr albums was grown using this method.
Update 2017: A new video showing mushrooms fruiting outdoors from blocks grown using this method. ua-cam.com/video/eraFjLDmZI0/v-deo.html
beautiful flickr
Thank you. For the curious, here is the direct link to my unsorted photostream, check out the albums as well. www.flickr.com/photos/wildbranch/with/37043711946/
Glenn Coville very inspiring to see your photos!

That is one of the best videos on how to grow I have seen to date. clearly a well thought out process that is easily replicated. If you had included the results of the demonstrated process the video would have been perfect.
+SocietyofEnoch Yeah I want to see what the fruiting bodies look like as well :D
+SocietyofEnoch I had seen few of your videos. Great videos though however You haven't posted the result of those videos. Ex : 2b. Growing Oyster Mushrooms at home - Wheat straw
Just tried this today. With Blue Pearl King Oyster mushroom. Used 10 to 15 percent grain spawn to hardwood pellet mix. Total of 12 bags each 4.2kg (2kg pellets, 2kg water, 0.2-0.3kg grain spawn)
Will update progress as it goes on. Temp ranges between 14-20 C
Update: day 2 - mycelium is starting to spread, no contamination so far as far I know (am new to this..)
day 5 - slow mycelium growth, but no contamination so far, people report contamination on day 10, so we will see
day 9 - found 2 dots of green mold in 2 bugs but mycelium is growing strong around them. Sepereting them and leaving it to see what will happen
day 12 - all bags got havey contamination of green mold...
day 20 - green mold spreded over mycelium.
Should had added double amout of spawn, mycelium held the laine vs contamination for a very long time. And should had mixed pellets with grain spawn before puting it in bags. Witch made it way harder to mix it, contamination apered where it wasent mixed as it should had been...
Typically contam will overtake desired mycelium. You may be able to get away with this if the pellets are pre pasturized, but even then it's a huge risk bc of spore contamination during transit.
You're best off pasturizing your substrate to reduce loss from contam, and even then it's not 100% perfect
This is because in the video he used straw pellets. You used wood pellets which require sterilisation
@@SamJohnson-gt3oj well not really, repeated it later with more grain spawn and it worked
@@Vinc94Machinimadid you use black pearl again the second time?
@@pajo2012so far did it with black pearl, normal oysters, shiitakes, lion mane... It works, but takes a lot of grain spawn (20% atleast) and you really need to mix it well... I just upgraded to pasutrazing my substrate with "EZ Bake Barrel" method. Way less contam, and using only 5-10% grain spawn.
Point is, yes it works but mix it really good and use lots of grain spawn
Love the simplicity of this Tek man. And my compliments to the cleanliness of your working area.
from his website - "This "cold" method requires no heat or chemical (lime or hydrogen peroxide) treatment because the sawdust has already been subjected to pasteurization temperatures and thorough drying when it is made into pellets. Mold spores are going to be present in the mix, but I can out-grow them by using plenty of quality grain spawn, and by creating environmental conditions that favor the mushroom mycelium."
manvstaco I call bullshit. 7-10 days he's got some green fuzzy shit in those bags. And..he wasted 40-50 dollars worth of spawn which he could have done hundreds of smaller logs the right way. Silly shit.
you don't have to worry about contamination if you use low nutrient wood pellet.
I just get a bucket, put 20% spawn and and wood pellet. then pour in pure water.
@@davidmiddlekauff6248 it seems strange he wouldn't show the results, that's for sure
I’ve tried this twice now with filter patched bags and incubated at about 77 degrees F for whites/goldens.. green mold both times in about 10 days.
If you follow him, you will see many, many spawn bags fruiting in his yard.
how many pounds can you expect to harvest from the 40 pounds of substrate you start with?
If the people asking all the questions would just go to your website, they would see that it answers many of their questions.
Why is your commercial website not working?
Any chance you can figure out how to grow cordyceps mushrooms? I didn't find that anywhere on your site.
By the way, I love your choice of music on this, and Moonlight Sonata, movement 1 on whichever other video that was.
Hi Glenn, do you think it is possible to re-use the plastic bags after peeling back to harvest turkey tails?
Trying to cut out the need for single use plastic
Do you increase the amount of spawn used to make up for lack of supplementation?
hi glenn! Thanks for sharing your experience. A few months ago I tried your technique with reishi obtaining very low results (no contamination), perhaps it is because I did not use spawm enriched with minerals. Can you tell me what% of gypsum and dolomite is recommended by weight of substrate? Cheers
I received an Oyster Mushroom Growing Kit from Dunecraft which has hard wood pellets, which lead me to this video. I feel like an entirely new world is opening up to me! I've been watching "Grow your own mushroom" videos for the past two days, lol. Thank you for sharing this video; I love your set up! Nice and clean. I can't wait to explore your channel and website. Thanks again!
Nice Vid Glenn ! in 0:54 you shake your spawn bags before dumping them in to the saw dust. That's not the 1st time you do that I believe. Would you tell how many times and on what period of time you shake them before they are ready for the pellets?
Thank you !
Impressive to say the very least. great video. If you don't mind my asking, what is the expected failure rate (hope I am using the correct term for it) for contaminants such as trich given that there is no pasteurization step? Genuinely interested in this technique as I am having to do this on a shoestring budget so anything low-tech and simple is definitely of interest. Thank you for your time and info and for releasing this video.
Dread - Yo, how's the mush coming?
Really enjoyed this video, really simplified a lot of concerns I had from simply reading articles. With this video seeming so simple I feel a lot more confident in taking a step into trying to grow some mushrooms for personal consumption. As a quick question how long would you estimate the entire process from start to finish this takes you to complete this. Thanks
Can you please show the outcome of the growing process. Also what is your contaminant rate using this cold method?
What is your ratio of spawn to substrate?
Nice vid. Would this method work with softwood pellets as well? Or would the need pasteurizing first? Also, What mushrooms are you growing with this method? Thanks for the video (make more) ;)
+Don charbonneau most mushrooms dont grow well on soft wood that is why it would not work.
I can't stand people are keep asking the result. Just go to this website and see the results. Is it too hard ?
Glenn Coville says Go to my website at coldmushrooms.weebly.com to see the results and learn more about it. Every mushroom on that site and in the flickr albums was grown using this method.
Interesting, so I guess that sterilization and humidity control isn't really necessary? Other mushroom growers on youtube show that.
Imo contamination is different for everyone, cold temps help but in different parts of the world and times of year you are going to have extremely varying amount of contaminant spores in the air so this method can work but it depends on these factors.
Now this will have a higher contamination rate than sterilized substrate but how much will vary and it's up to the cultivator to see if the numbers add up.
Thank you for your thoughtful reply. And yes, I can agree with your assessment. I would add that the biggest single factor is the species and variety of mushroom. For instance, P. ostreatus and T. versicolor almost always work for me in a variety of parameters, while H. erinaceus is more difficult and I need to absolutely keep the temp below 65F during the first 72 hours after inoculation. I've also tried shiitake, maitake and G. lucidum, but had little luck. Although, I've had consistent success with G. curtissi.
Overall, this method should be considered experimental and generally risky.
Did you build that metal frame that the barrel is mounted to or did you re-purpose it?
I'm still running your same technique 3 years later! Hope you are well!
how much grain spawn, in pounds, do you add to the 45 pound pellets?
why not just put the pellets, the water and the culture in the bag, shake it, seal it and be done?
I would like to have seen the mushrooms resulting, though
Great video loved the music. keep up the great work and need to see the harvest video too.
Nice! Thanks for speeding the action so we aren't bored stiff and.insulted by watching the same basic moves for many minutes.
Hi Glenn, thanks for this video, i gather a lot of inspiration from this; what are the dimensions of the bags you were filling, and where might one get some of them? i'm a new subsciber, i'm going to binge on your other videos; i'm wondering what area of the world you occupy? thanks again.
No follow up showing results.
Молодец!!!
Have you tried supplementing? and Do you see any differences with supplementing them with some food = wheat/oat bran like in other guides?
This blows my mind after watching video after video of growers sterilizing their sub straight. You make it look so easy and look at the success your having! Bravo!!!! Do you offer more educational information?
very good ive been using this method succesfully for my operation!
would you say you like this medium more than cotton seed shells/straw? also I'm looking into getting into cultivating mushrooms. Would you ever do this as a full time job if you had the space? Also, I've seen many different ways to grow mushrooms (specifically oysters) such as hanging log, lied down log, bucket, and then these half bags that they grow out of the top. What have you found to be the most cost effective and most productive method overall? Thanks for the help!
What is the time frame like after the logs are fully inoculated do you see pinning and eventual mushrooms start to come out? What kind of temperatures do you keep the logs at after mixing?
I can't read this fast!!! Lol
Think I'm sold. I'm going to try this method. Excellent and concise video. If it works and we get off the ground, I'll definitely make a small donation!
What is you contamination rate at?
No pasteurization needed?
When sterilization is...?
Hermosos tus vídeos, la música, el tiempo. Saludos desde Chile 🌌🌾🌅🌄🐎
OMG!!!! LOve this video....I so want a mushroom farm!!!
Im digging the music. Anyone know who composed it?
in the description
Genius!! Thanks for posting. You seem to have figured out the formula for low labor mushroom growing.
Would it be ok to use mahogany saw dust? Thank you
Can you use stale nuts as a substrate or a supplement to grow mushrooms? No shells or salt.
You ever have issues with contaminants or do you cold incubate? still dont understand how this is done open are and with out sanitation? thank you
Thank you for the video, Glenn. May I learn what do you mix the grain spawn with before adding to the pellet slurry? Actually I'm trying to understand the exact amount of grain spawn you added.
How'd you rig up that mixer, what tools are involved?
Hey Glenn, thanks so much for posting these wonderful instructional videos. I was wondering at what temperature and humidity you keep your grow room, and what methods you use for regulating this indoor climate? Also, I was wondering if you have to fluctuate these settings much for different kinds of mushrooms? Thanks again!
Wondering if you've tried a similar method using straw? Maybe boiling the straw for 20 mins or so then cooling quickly then bagging up with the mycelium..
dont boil straw, pasteurize or lime soak....also he is not growing oysters.
Hi Glenn! I know it's an old video.. but how much spawn did you use in this video in relation to those 82 pounds of substrate? Very much appreciated 😃
1 bag (7-8 lbs.) for oyster, turkey tail, golden reishi. 2 bags for bears head and lions mane. Check out coldmushrooms.weebly.com/ for more details.
No pasteurization at all?? And the results????
That is good ..it is manual prosses..nice 👍👍
Beautiful music ,nice video ,thank you 🙂
You're the man!!!!
One of the best videos on reishi mushroom cultivation. Simple and easy. Though this remind me of charlie chaplin.
You have not realised it but this is the best video on mushroom substrate treatment so far
Do you use this method with all your mushrooms, or just oysters?
Great video! Thank you for sharing - I'm curious what kind of grain you use for the variety of fungi you grow? Do you use different recipes for different species or have you found one that all these wood lovers thrive on?
no mold or bacteria issues? I don't see a lot of pasteurization or sterilization going on there.
Hey Glenn, do you re-hydrate your log-bags?
I love this. Zero talking straight to the point and definitely some great ideas in here I'm going to steal
I haven't seen sawdust (pellets) grown in those kind of bags very cool!
That's so cool
Do you supplement the substrate at all to increase yields? What is your biological efficiency using this method?
Please May i know what do you call for the plastic bag you are using.. Thanks
Poly-tubing, 4-mil for the tall bags shown here. 3 mil for the smaller bags shown in other video. Just cut lengths and tie off ends with string. www.uline.com/Product/Detail/S-5866/Poly-Tubing/3-Mil-Poly-Tubing-Roll-14-x-1500
where do you buy those large bags you filled with spawn material and poked them? What is the size please?
I'm using 3 mil 14" (flat measurement) poly tubing now: www.uline.com/Product/Detail/S-5866/Poly-Tubing/3-Mil-Poly-Tubing-Roll-14-x-1500
However, this is for the smaller 20 lb. bags that I'm using for outdoor row cropping as shown in my other video. For bigger bags, as shown in this video, I have used 4 mil.
verry impresive where i can bey the empty bags.? thx
Hi. Can I ask you to show me the sawdust pellets, how do they look like
Did you sterilize anything at all? Hands? Loading chute? Tub?
No. The barrel and tub get rinsed with cold water. The chute gets wiped down with a clean cloth. My hands are washed with soap and water.
Nice! And apparently this works well?
+Tharindu Tharuk Kindly remove your spam. You have been reported.
***** Not sure that reishi would work out with this method. Oysters maybe, reishi........not a good chance in my opinion. Let us know how it works out.
Xanous Lan exactly . He's using about 15lbs of spawn to 40lbs (dry weight) of substrate. That's a really low ratio that's almost 1:2. Definitely curious to see the yields
untreated, meaning not even pasteurizing?!
can you do this with sawdust spawn or does it have to be grain spawn??
Thanks for the video!
I'm attempting to grow saffron milkcap spores, and can't find any info on growing them indoors. Since the grow in pine tree forests, I bought pine sawdust, and collected some pine needles. I also bought some coco coir to possibly add to the mix. I plan on following your method as far as putting everything in a propylene bag and punching holes in it. I'm open to all suggestions or recommendation you have! Do you think the pine sawdust/broken pine needles/coco coir mix would work for the coniferous loving saffron milkcap? Thanks:)
If you'd put it trough a pellets machin i guess it would work better, at the extreme heat caused by pressure to do it will sanitze enough your substrate if it is still enough 'selective'
Excellent. Everyone else is teaching the heating method which has not worked for me that well. I get a lot of green mold for some reason, no matter how careful I am and how much alcohol i use to clean everything. I will try this technique. I will visit your website as well. Thank you for sharing your technique Glenn. Cheers...
@Thomas Hancock I think his success with this method is due to the very high spawn innoculation rate. He used 3 bags (estimate 5lbs each) on one bag of sawdust pellets ( ~40-50lbs). So, about 1/3 of the substrate is spawn which can outpace any bacterial growth. This high spawn rate also explains the huge flushes. So, I guess there's a trade-off.
@tekno mytekno his website says 7lbs spawn to 40lbs pellets. So closer to 1:6 ratio. I’ve tried twice at that ratio and got green mold both times.
I thought there was pine wood in those pellets? Maybe not so much that you can't grow shrooms on them?
It depends on the brand.
And what is grain spawn looks like in close site
After the mycelium has spread through the pellets, could you use this to inoculate oak logs?
I think you could. It's essentially sawdust spawn. Perhaps you could even fruit the bags 1-3 times, and then use it to inoculate logs. I'm going to try some of that this season.
Sorry, 1 more question: How and what is your barrel mounted to? :)
Looks to me like he has a pipe going right through the middle of the barrel. He doesn't have to worry about water leaking out because he's only putting 5 gallons in there, and it gets absorbed by the pellets pretty fast. My theory, anyway.
Thanks for this video Glen.. I was just wondering if you have ever made grain spawn without sterilisation... I was thinking a 15 minute boil to hydrate and kill unwanted pathogens then cool quickly, bag up and inoculate with spawn.. Have you tried that and if so have you had good results? Thanks again.
have fun wasting time and money that way....do proper or go buy spawn
It seems that grain is too rich, compared to woodpellets, so it attracts too much différents pathogens.. thats why it need to be so much sanitized
After the 2-3weeks then where do you put them? How's your BE with this method? Thanks
The larger bags are put into a growroom, but I also have been making smaller 10 to 20 lb. bags that are put outside under row cover as shown here ua-cam.com/video/eraFjLDmZI0/v-deo.html
I don't have BE numbers ready right now. I think the BE metric is flawed because there is too much variation in the weight of fresh mushrooms, especially oysters and lions mane. I can take the highest quality low-moisture mushrooms and literally double the weight by turning up the humidity. It would be far more meaningful if biological efficiency was figured using dry weight.
How do you make the grain spawn?
Very helpful video, thank you!
Love your efficiency!
Have you tried this tek with Shitake at all?
Yes, but only with 2 different varieties. Both didn't work, massive contamination within 7-10 days. Same with Maitake. But those were alsodone on northern hardwood mixes. Next, I would try with pure oak pellets.
Thanks. Very helpful.
Will these method work for growing “shiitake” mushrooms?
I have not been able to make it work for shiitake, but I have only attempted it twice.
Great video. Do you have to sterilize the saw dust before you inoculate?
The sawdust is just mixed with cold water, there is so much spawn added that it outgrows the bad stuff. He has this info on his website in the description of the video.
No gypsum or coir or anything?
Could you share where you get your medium bags from? thanks David
Either 4-mil unpunched 8" diameter convection tubing available at hydro-gardens.com/coolingventilation.htm#ConvectionTube or 4-mil 14" flat poly tubing available at www.uline.com/Product/Detail/S-1986/Poly-Tubing/14-x-750-4-Mil-Poly-Tubing-Roll
Both products are basically the same thing (but measured in different ways), they both work well, and the price is about the same. I thought the convection tubing was a little stronger and less likely to get stretched out during packing.
When should you start to see mycelium running in the larger bags? What's yours incubation area factors, is there fresh air coming into it? Thanks just tried a batch of oysters this way yesterday. Thanks again
You should see healthy growth around the grain spawn in the first 2-3 days. Within a week, you can tell by the uniformity of color in the sawdust, if it will be successful. At this stage, the mycelium is hard to see. At 2-3 weeks, it thickens up and you should be able to see mycelium everywhere.
My incubation area is open to fresh, unfiltered outside air. However, I found mushroom gnats will lay eggs directly into oyster bags, through the punctures, even before they fruit, so now I keep them under bug screen.
Glenn Coville I think my room is too cold the bags read around 40f.
Tradd cotter uses a needle paddle for the fresh air holes first. He says this makes it so you get air flow in the bags but the holes are too small for fungus gnats. Then when ready to fruit just make bigger holes.
Great process you have going there.
No heating?
someone tell me why that barrel keeps moving? Ive been researching propetual motion energy generators and that right there might be a key component!
I see you havn't sterilized the sawdust in the video, is this nessesary?
It's a waste of time....after few years in this business, I.ve realized u can grow mushrooms in an unsterilized sawdust
Amazing
Totally awesome set up.
i love the Vivaldi in this!
When did you put the lime with your sawdust?
Iirc he didn't use line or heat, simply high amounts of spawn for a given amount of pellet so that the spawn outgrows the bad stuff. I'm personally going to go ahead and continue to sterilize everything just as a preventative measure and since the grain spawn is more expensive here by a large amount but maybe I'll give it a try some time since he was able to get it to work consistently.
@@lazyh-online4839I I understand why somebody only cook straw or coffee ground without lime.
The music....what is it?
read description
Ye that’s fine for your “little batches” but get serous forces sterilization!!! Wait till he gets multiple bags that all are contaminated!!! It’s sucks!!!
He also adds so much more spawn to the bags than normal inoculation, this helps it outgrow the bad stuff.
