Some clarifications please. You say that coffee grounds have already been pasteurized. But from what I gathered from other videos, they say this only applies to newly (no older than 24hours) used coffee grounds. If this is the case, can old coffee grounds still be used by pasteurizing them again?
@@j.l.thurman2725 Every time I try to use coffee un sterilised, I get mad contamination, Trichea is common but sometimes some of that white bacteria that's all over humans too. I always sterilise my grain, substrates of straw + coffee and agar media, I just sterilise the lot, every time I've experimented with pasteurising, utilising a still air box sterilised and left for air to settle, I've gotton contams that grow out of control and stunt the mycellium, sometimes cutting off whole areas of substrate. Even when I do the mixing in open air, I always get contams that way.
Thanks for this video Adam! Very helpful. I'm a total fresher at this, so I have a few questions. Is water to be added to the substrate? How much? Should the bags be pierced for the fruition process? or the mushrooms just tear the bags and grow out? What kind of environment/temperature needs to be maintained throughout the process? Can button mushrooms be grown using coffee grounds?
Dear Nieha .....so it's been a whole yr now.....have you pressed forward with growing mushrooms??? Anything you'd share would be a blessing.....I don't know if it's actually worth it....seems like waaaay to much work....the thing that gets me is all the grow labs I see on these videos..... always makes me think my house isn't even that much of a controlled environment....how the heck am I gonna do that for mushrooms???
Super! I'm living in Vietnam but am from Canada. I have been gifted boxes of these at home to grow on the kitchen counter. Super awesome! What I am wanting to do is show a young struggling family here during covid, how to make some extra money by making these as they have a tiny coffee shop. I thought what a great idea. As it's very difficult times for the average vietnamese person right now. Question ❓ where would I get the straw from? Or is any straw good? They have really strange mounds all over the country side whee they produce mushrooms for markets but I thought this guy could do it for gifting like in the west. Cheers great video 🙏
Hi I really like the video and the idea of using spent coffee grounds. So far I'm using them only in my vermicomposter with great success. The issue I have with them is although they are sterilized in process of making coffee, they tend to catch mold very quickly. How do you address this issue? Are there any storing methods to help this?
Yes, this is what I also noticed. I think it is not practical from the coffee grounds that come out of a single machine. He mentioned that they use the coffee ground within 24 hours. So, my guess is that they procure coffee grounds from large number of coffee shops and use it within 24 hours. Storing grounds won't help in this case.
Love the experiments/experience here. One question? Have you ever tried to inoculate a coffee/straw substrate bag with a spore syringe? Skipping the grain spawn all together.
Thank you for this demonstration! I'm trying to practise at home currently and have a quick question. Do you pierce the bags during incubation phase, or only fruiting phase when the mycelium has taken over the substrate?
its rare that Ive been impressed however watching this certainly would make anyone say wow I need to ask - have you checked out the site called gregs mushroom grower just google for it
@@GroCycleTV yes I have seen and read about using coffee grounds to grow mushrooms 🍄 and Mushrooms 🍄 can me grown on any farm substrates I have watched a video of you talking about that all we need to do is look and following you was the best 👌 idea 💡 from 🇨🇦 #YSW I follow you 💯 from Domenico Monteleone
I'm wondering too, but assuming the straw has been pasteurized (they have a video) at least, or sterilized (which they wouldn't recommend for Oysters). So I think the straw is pasteurized in this case, but they didn't state it in the video.
We own a coffee roaster so I’ve been wanting to do this for a while now. Would it help to grind the coffee more course? I also was wondering if mixing in the coffee chaff would work the same as straw or sawdust. Which mushrooms work best or do only oyster mushrooms work?

Great video. A few questions. What kind of bags? How do you seal them? Where do you store them? How long does it take? Where do get 'spawn'? Thank you!

I have been studying for a year and how to grow mushrooms I think the best thing to do is get a closet Martha I believe closet I tried both on my own time it gets contaminated lots of alcohol and a warm old-fashioned steam also I do believe that you do need it’s a monitor and a humidifier gauge if you use a bucket you need to put a holes in them with filters you need to use sterile water. They did great this time except for the last phase the fruiting phrase you have to be extremely careful not to use any kind of water that has bacteria in it. Also you have to make sure that you have the proper light the proper heat in the proper humility is very difficult to grow mushrooms but I swear it’s worth it. DM me if you need more information 248-807-4607 enlightenment abound
I would say your technique using coffee ground is awesome.. Have a question - While closing the incubated plastic bag , do you let air inside the bag before securing it or do you puncture them for natural air to pass through for mycelium to grow and formation of mushroom pins? 2) 20 % mixture of straw is definitely a great idea , can we use any other form of substrate? Have you experimented on any other type of straw or similar stuff 3) Can you send me a link of your app or something..love to follow you guys..
1) the bag at the end has a 2 to 5 micron filter patch. This is where fresh air exchange takes place. The long bag that are hanging would need to have some small one-inch x’s cut into it for air exchange and for a place to pin. 2) oyster mushroom are aggressive eaters. You could mix in pasteurized peanut shells, Aspen chips, cardboard, that doesn’t have a glossy surface or colored ink, and other carbon rich materials.
I'm trying to start out growing my own mushrooms for food.... I'm super broke but I have a lot of imagination and a pretty big lot in the backyard so this video was the first one that makes me feel like I actually got my foot in the door on how to do this cheaply and semi proficient.....can anybody please point me towards some more videos like this one in terms of step by step/ strategies/ do's and don'ts pleeeeeeees????? Thank you for any help in advance!!! Mother nature is free and should not be monopolized !!!!
Thanks. I will do this. I live in a city and it seems the easiest and best! Im cooking up a pound of coffee. I also like that you put it back into the same bag!!
I am new to growing mushrooms. This is my second attempt and I’m growing it in the tub is taking so long the fruits I see no mushrooms growing I see them Iceland it’s been two weeks how long should it take to start growing mushrooms. I mix sterilize dirt with my spawn was completely colonized. I do see one black fuzz growing in one of my pockets is that what I should cut out of a hydrogen peroxide on it is that a sign that it’s contaminated? Thank you so much for your UA-cam channel is teaching me a lot thank you thank you thank you
Hi Eric & Adam do you think that instead straw that I can use grass weed what is plentiful here on the beach, to be honest it’s posedenia oceanica, a very kind off flaky material what withhold a very good water content.
Thank you for your video! I have a question that might be obvious, but I just want to know for sure: How do you cut your growbag to allow the fruiting bodies to grow out of them?
👆 that's the Instagram handle of the legit dealer that ships mushrooms spawns and spores to me, after i was ripped off my 💰 severally by online scammers. Dude is a life saver I was scared at first but when I received my package I was so ecstatic because it was worth the $
Great content, thank you. I’d like to know more about how you go about reaching field capacity of the grounds and straw. Meaning, how to do go about hydrating the straw to 75% and coffee to 50% before bagging?
I've started growing mushrooms, and I know the owners of several local shops. I'd love to get my hands on the spent grounds and mix it with sawdust and a rye grain spawn.
Coffee shops..... Just ask coffee shops for them. They are usually happy to give them to people for free. Starbucks coffee shops in my area usually has big bags of used grounds that they put out for people to take for free. Just ask them for them if you don't see any. They're usually very happy to help. OR... You could just save your grounds whenever you make a pot of coffee, just put them in a container and place them in your freezer until you have enough grounds saved up. Then you can put them all in a large pot, add some water, and boil it. This will kill off any mold or other harmful pathogens you don't want in your grounds. I hope this helps you.
Heather Donigan One thing Heather like they said it’s better if you mix straw with coffee grounds but never throw coffee grounds because they’re good for roses and all kinds of different plants. Including the enlightened ones meaning Magic mushrooms. And don’t forget if you do and just them they turn from 37 says Celeban do your homework and it’s not something that shows up in a drug test. If you’re interested look at John Hopkins study and they’re calling it a miracle and that would be the scientists. Good luck to you all I will spread this as far as I can it’s worth 20 years of meditation because it dissolves the ego. Love you I’m Johnny Appleseed I don’t want to spread it everywhere I’m still working on my part because I can’t I’ve done it twice and I can’t seem to do it but I actually know what I did wrong this time do you have to have at least 4 inches of dirt, sterile dirt in a bucket or get Martha’s fruiting chamber. Good luck to you guys love you all
Thanks for sharing this! I was wondering if I could mix wood shavings from my workshop with the coffee grounds and how I would go about pasteurising them
Excited to get my mushroom farm rolling. When storing coffee grounds in preparation for making the substrate, should the coffee be dried out to prevent mold or will it be safe just stored in a jar in fridge?
They recommend using fresh coffee grinds (ideally from an espresso machine) within 24 hours after they've been used. The heat from the steam running through the coffee puck, pasteurizes the C grounds.
if the coffe is moist for too long you can get get some unwanted mold! you can dry and store it until it's time to use it, and then pasteurize it again
Great, but do you make holes in the bag or do they break through? Where do you get the bags? Do they need to be in the dark or is light fine? Can you provide where you get your supplies?
Eric and Adam, thanks so much for the generous and informative materials you put out about your process. I’m unclear about whether your substrate mix is homogenous with spawn mixed throughout, like the mix that’s made at the end of the video, or whether the spawn is added in layers. Your bags in incubation, as photographed, seem to have layers of spawn that have been added, at evenly spaced intervals throughout the bags. Or is that just the spawn growing out in a layered sort of way within the homo mix? Greetings and thanks from NYC. We’re experimenting growing mushrooms in NYC, on coffee fermented with EM/bokashi.
A question here and not on Google just because I love your vid and I believe that in my city all coffee shops just dump their grinds, this is a great way to reuse that matterial. When you put the mixture in the bag, do you make holes, or how does the mushroom get to grow on the outside wall? Edit: downloaded the ebook, let the comment stay just to tell you how awesome you guys are :D
Great video! I am just curious about one thing, I see when everything is mixed you get a uniform mix but when you show your bags on video with different level of spawn progression I see properly arranged layers. What do those layers consist of?
It looks like he's adding a layer of the coffee/straw substrate, then a layer of mushroom spawn (usually on grain), then repeating those layers until the bag is full.
If all goes to plan your coffee will be fully colonized, this you could use as spawn for a new batch. I think the rule of thumb is to add to your total substrate mix 10% of spawn. So if you have a fully colonized bag that has fruited several times, just take out 80/90% of the bag and mix the remaining spawn with fresh substrate, I think that should work.
@@Supergn0me 185* F, for an hour or more to pasteurize. 250* for 25 min, in a pressure cooker to sterilize, let it cool naturally before decompressing. good luck.
Thanks for your video. I keep watching it. Just a note that in coffee grounds there are also non-brewsed coffee grounds as coffee shop staff says they sometimes put coffee grounds leftover from the grinder in the coffee waste bag. Maybe it can create mould too. A question: how about using wood pellet? Can I use it in the same way you do with the coffee grounds as it's pasterized already?
good point about the unused coffee.. and you can use wood pellet instead. i used coffee grounds, but didnt work for me - always got contaminated -so now i only use wood pellet and recently started experimenting with cardboard as shown in one of their videos.
Nice channel. So happy I've found you. I was thinking, you said that coffee ground would actually develop competing mold if it's old than 24hours, so I was wondering, can I deep freeze the coffee ground until I have bigger quantities? So that way I shouldn't have competing molds in it? What do you think? Thanks!
I know this is a dumb question, but after filling the bag do you poke holes in it? If so, how big for the bag size that the gentleman with gloves filled? I thank you in advance for your advice.
Where can you get coffee from ? Can the coffee be frozen for freshness ? I saw your course and once I get my self on my feet after lockdown I’ll get the course
Hello, I have read your e-book. But I got 3 questions 1. How do I water them during the first 2-3 weeks, when the mixture is still sealed in the bag? Or simply I don't need to water them during that stage? 2. After the first 2-3 weeks, you said that we need to cut some holes and water them. Should I water it directly to those holes or from the top of the bag? 3. Will wooden furniture next to those mushroom farms affected by those newly growth mushroom spawn? If yes, is there any suggestion to avoid it?
1) no need to water during incubation, there i enough moisture in the substrate already 2) spray water where the holes are cut 3) this is not normally an issue unless the room the wooden furniture is in is very humid.
Hi, might not get a reply since its been many years. I've recently tried this with brown oysters (winter variant) took 44 days to fully colonise, but have been trying to pin for 20 days without luck (at temp of 10C). I have other medium (bags) in the same conditions which have fruited and harvested. Growing in 100% coffee, what type of oyster did you have success with?
Awesome, thanks! Just a quick question..... I can only get hold of a small amount of coffee grounds each day, and I see they need to be fresh to use. Can I freeze them until I have enough?
I've been spending time with the help of my son researching into growing mushrooms at home then we discovered an awesome website at gregs mushroom grower (check it out on google)
here's several things worth trying pick the best type - there are lots available. grow them in the right environment - some eg oyster muchrooms like cool humid conditions and can be put outdoors (I read these and why they work on Gregs Mushroom Grower website )
Has anyone tried using this method outdoors with strains chosen for the outdoor temperature parameters? I am interested in doing this in reusable 5 gal buckets to minimize plastic waste. Also curious if anyone has tried with wood chips in place of straw or a combination of the two with coffee grounds. Paul Stamets mentions that wood chips promote prolific fruiting in combination with other more finely ground substrates as they provide dense pockets of nutrition. I am also experimenting with lime pasteurization of sawdust pellets and straw. Had anyone tried this method with coffee grounds that are not optimally fresh?
Thanks so much! Such an inspirational video! I am gonna start growing mushrooms on a small and self consumption scale soon and, as an Italian, coffee ground is something we are never running out ... may I use one of those big yogurt boxes (1.25 kg box) with small holes instead of the plastic bag for the process? What do you reccomend? Thanks!

Hi Adam and Ian. Thanks for the videos. For incubation, what is the recommended moisture content during that time? Is water added?
Field capacity. This means if you squeeze it gently it would just produce a drop or two. If you squeeze it hard it runs.
What do you do with the coffee and straw mix that's left over after several flushes? Can it be broken up and used as compost in a garden?
The left over will still have mycelium in it so you could let it produce again or you and put it in your garden for the mycelium to help your plants

I’m unclear about whether your substrate mix is homogenous with spawn mixed throughout, like the mix that’s made at the end of the video, or whether the spawn is added in layers. Your bags in incubation, as photographed, seem to have layers of spawn that have been added, at evenly spaced intervals throughout the bags. Or is that just the spawn growing out in a layered sort of way within the homo mix?
Greetings and thanks from NYC. We’re experimenting growing mushrooms in NYC, on coffee fermented with EM/bokashi.
with smaller bags we throughspawn (mixed throughout) and with larger column bags we tend to inoculate in layers
Could I use coco coir instead of the straw?
1. Why do you use only 10% spawn with coffee grounds?
2. Is it wise to add sawdust and do you need to pasteurise sawdust?
Thank you!
What type of the bag do you use?
A question here and not on Google just because I love your vid and I believe that in my city all coffee shops just dump their grinds, this is a great way to reuse that matterial.
When you put the mixture in the bag, do you make holes, or how does the mushroom get to grow on the outside wall?
Edit: downloaded the ebook, let the comment stay just to tell you how awesome you guys are :D
Great video! I am just curious about one thing, I see when everything is mixed you get a uniform mix but when you show your bags on video with different level of spawn progression I see properly arranged layers. What do those layers consist of?
white layers are spawn growing at different stages during colonizing from your left all the way to the last two on the right fruiting stages
It looks like he's adding a layer of the coffee/straw substrate, then a layer of mushroom spawn (usually on grain), then repeating those layers until the bag is full.
Do the mushrooms eat through the plastic?
Is there an alternative to those plastic bags?
Can you please explain why do I need to use the substrate with the coffee ground?
Thanks in advance.
I think the hardest thing to do with all this is pasteurizing the straw. What (how) is best way to do this at ones home? Thank you!
Hi, thanks for this very informative video. I’d like to know if you can re use the coffee ground after you harvested your mushrooms? Thanks
If all goes to plan your coffee will be fully colonized, this you could use as spawn for a new batch. I think the rule of thumb is to add to your total substrate mix 10% of spawn. So if you have a fully colonized bag that has fruited several times, just take out 80/90% of the bag and mix the remaining spawn with fresh substrate, I think that should work.
Thank you so much for all the videos from you, they all are very helpful for a people like myself
Is mould dangerous, or does it just reduce yields/cause complete failure?
What about if you were using spore syringes?
What about adding cardboard to the coffee instead of straw?
Great video! One question because I didn't catch it, do you need to pasteurized the straw before you add it and how?
@18 Hands Ok, so exactly how does one heat sterilize properly?
@@Supergn0me 185* F, for an hour or more to pasteurize. 250* for 25 min, in a pressure cooker to sterilize, let it cool naturally before decompressing. good luck.
Thanks for your video. I keep watching it. Just a note that in coffee grounds there are also non-brewsed coffee grounds as coffee shop staff says they sometimes put coffee grounds leftover from the grinder in the coffee waste bag. Maybe it can create mould too. A question: how about using wood pellet? Can I use it in the same way you do with the coffee grounds as it's pasterized already?
good point about the unused coffee.. and you can use wood pellet instead. i used coffee grounds, but didnt work for me - always got contaminated -so now i only use wood pellet and recently started experimenting with cardboard as shown in one of their videos.
Nice channel. So happy I've found you. I was thinking, you said that coffee ground would actually develop competing mold if it's old than 24hours, so I was wondering, can I deep freeze the coffee ground until I have bigger quantities? So that way I shouldn't have competing molds in it? What do you think? Thanks!
yes freeze it and then when your ready thaw it and pour boiling water over it to help re sterilize it
I'm drinking as much coffee as I can to try this!
Lol ask Starbucks or other coffee houses for free grounds! I got a big sack from them and I’m going to go back for more 😆
Wow! U gave me an idea, thanks
“Grounds for your garden” is a program Starbucks started back in 1995 I think. There are many great uses for coffee grounds.
Hi guys can you share size if your bags?How much they weigh with coffee spawns and straw? THANK YOU!!!
Wow your video is very insightful. Kindly inform if insect infested barley grain be used as substrate for mushroom growth
Really great method, thanks for sharing!
I know this is a dumb question, but after filling the bag do you poke holes in it? If so, how big for the bag size that the gentleman with gloves filled? I thank you in advance for your advice.
what are your thoughts on coffee and re-hydrated wood pellets mixed?
Have you tried mushrooms other than Oysters? I would particularly like to try Shitake, Chicken of the Woods and Miatake.
I’ve tried many times to grow on coffee grounds, with zero success.... but I’ll try again
Thanks for all the great advise :) Could you use hardwood oak pellets instead of straw?
Can we use Green Coffee grounded instead of used coffee grounds from roasted coffee ?
Will it have better nutrition?
Where can you get coffee from ?
Can the coffee be frozen for freshness ?
I saw your course and once I get my self on my feet after lockdown I’ll get the course
Could you also use coco coir instead of the straw?
Came here to ask this.. did you ever try it?
Hello, I have read your e-book. But I got 3 questions
1. How do I water them during the first 2-3 weeks, when the mixture is still sealed in the bag? Or simply I don't need to water them during that stage?
2. After the first 2-3 weeks, you said that we need to cut some holes and water them. Should I water it directly to those holes or from the top of the bag?
3. Will wooden furniture next to those mushroom farms affected by those newly growth mushroom spawn? If yes, is there any suggestion to avoid it?
1) no need to water during incubation, there i enough moisture in the substrate already
2) spray water where the holes are cut
3) this is not normally an issue unless the room the wooden furniture is in is very humid.
What are the dimensions of your plastic bag?
Hi, might not get a reply since its been many years. I've recently tried this with brown oysters (winter variant) took 44 days to fully colonise, but have been trying to pin for 20 days without luck (at temp of 10C). I have other medium (bags) in the same conditions which have fruited and harvested. Growing in 100% coffee, what type of oyster did you have success with?
yield wise, is it better to have 10 bags of 1 KG or 1 long tube containing 10kg of substrait mix?
I have plenty of muslin, could I use it to make bags for growing mushrooms in coffee grounds?
I'm not a mushroom expert, but I worry that the mushroom would eat the bag if it's made of organic material.
Where do you get so much coffee waste from?
Awesome, thanks! Just a quick question..... I can only get hold of a small amount of coffee grounds each day, and I see they need to be fresh to use. Can I freeze them until I have enough?
Could always ask your local coffee shop to set aside a day or two worth
use within 24 hours.
just discovered this channel, amazing!!!
Wow! Thank you! I'm so excited to try this 🙌
I've been spending time with the help of my son researching into growing mushrooms at home then we discovered an awesome website at gregs mushroom grower (check it out on google)
here's several things worth trying
pick the best type - there are lots available.
grow them in the right environment - some eg oyster muchrooms like cool humid conditions and can be put outdoors
(I read these and why they work on Gregs Mushroom Grower website )
Has anyone tried using this method outdoors with strains chosen for the outdoor temperature parameters? I am interested in doing this in reusable 5 gal buckets to minimize plastic waste.
Also curious if anyone has tried with wood chips in place of straw or a combination of the two with coffee grounds. Paul Stamets mentions that wood chips promote prolific fruiting in combination with other more finely ground substrates as they provide dense pockets of nutrition.
I am also experimenting with lime pasteurization of sawdust pellets and straw. Had anyone tried this method with coffee grounds that are not optimally fresh?
Can you use tea leaves from tea bags as well as coffee grounds?
Do you not add any water to your bag mixes?
would it affect the nutrients in the coffee grounds if you were to ix it with the grain spawn that you are about to PC cook?
Thanks so much! Such an inspirational video! I am gonna start growing mushrooms on a small and self consumption scale soon and, as an Italian, coffee ground is something we are never running out ... may I use one of those big yogurt boxes (1.25 kg box) with small holes instead of the plastic bag for the process? What do you reccomend?
Thanks!
I use plastic sandwhich bread bags sometimes and just cut small holes in it.
Can you grow mushrooms on unused coffee grounds?
Could you use vermiculite with the coffe to help it be less compact.
Where do you guys get those long bags from and do you make holes in them so the mushrooms mycelium can breath?
Would it be detrimental to mix several types of substrate?? any experience doing it that way (more than two types of substrate)
Do you have to poke holes in the bag or do they just pass through as they grow?
Would adding rehydrated wood pelletes instead of straw help the mix?
I wonder...could you use coconut coir instead of straw?
No direct experience but am sure other growers have used this.
thanks for your idea．can I use the coffee for shiitake mushroom?
Is it possible to do this is a self sustaining way or must I keep purchasing fresh spawn? Thanks.
is it possible to use bags from other material than plastic? Or is this plastic compostable?
