- We've been growing mushrooms on coffee waste since 2011, and in that time have turned 30+ tons of coffee grounds into more than 7 tons of fresh Oyster mushrooms.
Yet when you look around the internet you'll find countless people saying that it's not possible or that you'll just end up with mould.
The truth is, growing mushrooms on coffee grounds is a little more difficult than growing them on straw, but if you follow the tips and advice we give you in this video, you'll find good success.
You'll learn:
- Why coffee grounds are a great material to grow Oyster mushrooms on
- Why their small particle size can present problems to your substrate mix
- How to break up the density of your coffee ground substrate by mixing in some chopped straw

How long can you use a bag of substrate?
I'm gonna need to drink more coffee lol
I've got 3 pounds used that I dried to store. pasteurising it now to use for my spawn. doing 4 indoor bags and the rest in the garden
You can probably go to a local coffee shop and get what they throw away
McDonalds now leave a bag of used coffee grounds on the counter for people to take.
They will gladly give stuff to you they have to pay to dispose of.
@@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.
My very first trying of growing mushroom was using coffee grounds and dry gress mix. it was just happened 3 weeks ago, and so far so good...
Ive never got mold at all growing with coffee grounds
But I do mix my grounds with sunflower seed hulls.
Thank you so much for all the videos from you, they all are very helpful for a people like myself
Hi,I really do enjoy your videos, find them very instructive, add to it the good energy you transmit with it, thank you...
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!!
Really great method, thanks for sharing!
best video ive seen so far.. not only steps through the process (like everyone else) but awesome incite on why to do things a certain way
Aaaag come on now! Best video my a$$
We’re going to try this for our customers of our CSA here in North Pole!
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 )
just discovered this channel, amazing!!!
You guys are amazing .pls keep it up
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 🙏
Beautiful sustainability!
Thank you. great video, great info...
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.
Very helpful. Thank you. 😄
Thank you so much!! I don't have access to logs so this is a great alternative. Good luck with all of your work!!
Thank yous for sharing... great job
Awesome videos! Thank you for sharing your wealth of knowledge. Is the 600g of straw damp or dry straw?
Great information respect G
Great stuff!!! Thank you.
Thanks guys
I really want to thank you for sharing your knowledge. I am here in the Philippines and this video is amazing. what they teach us here is different. I would love to try growing mushrooms using this technique. Thank you very much 🙏🏿🙏🏿🙏🏿🙏🏿 I appreciate what you are doing !💯👌🏿🙏🏿☝🏿
Thanks Kasikmura, happy to hear you found it useful :-)
GroCycle Yes very helpful 🙏🏿🙏🏿🙏🏿
thank you very much / from Brazil ❤
Fabulous! Thank You!!!
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
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?
I'm excited ..
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 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 TH-cam channel is teaching me a lot thank you thank you thank you
Thanks a lot for video.
Thanks for tutorial
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???
I've picked some used grounds from gas stations, and Starbucks as well.
Amazing! Which tall bags do you use? They look ideal!
Thank You
Thanks for all the great advise :) Could you use hardwood oak pellets instead of straw?
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.
with smaller bags we throughspawn (mixed throughout) and with larger column bags we tend to inoculate in layers
Thank you for sharing this 🙏 ❤
I get my from an online store, they got shroom, psychedelic and microdosing products well refined, also ships to anywhere
He,s on Instagrams with the below handle

Thanks you
Thanks for your info-video. Just wondering how to grow Morels Mushrooms.
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.
Wow your video is very insightful. Kindly inform if insect infested barley grain be used as substrate for mushroom growth
what are your thoughts on coffee and re-hydrated wood pellets mixed?
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
Do you think coffee+sawdust would be a good combo to use?
Very useful video….
Hello one question on this….
Is there no need to pasteurize coffee waste before mixing it with the straw…
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.
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?
The substrate needs air so if you don't have a filter patch then you would need to pierce/ slit the bags
Thanks, I was wondering the same thing. Very helpful!
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
How do you pasteurize the straw that you use in the substrate?
Great video, does it have to be black cofee beans ?
There are several ideas worth trying
select the best type - there are lots available.
grow them in the best conditions - some eg oyster muchrooms like cool humid conditions and can be placed outdoors
(I learned these and the reasons they work on Gregs Mushroom Grower website )
Can I use a dried coffee ground for mushroom cultivation? (Dried under the sun, packed, and shelf life = 6 months)
Great video thank u can u tell me where to purchase the long bags
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 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.
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?
thanks for your idea．can I use the coffee for shiitake mushroom?
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.
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 add orbeez to the mix? Would that help the hydration or does it have chemicals?
Have you tried mushrooms other than Oysters? I would particularly like to try Shitake, Chicken of the Woods and Miatake.
Can we use Green Coffee grounded instead of used coffee grounds from roasted coffee ?
Will it have better nutrition?
Is it possible to do this is a self sustaining way or must I keep purchasing fresh spawn? Thanks.
yield wise, is it better to have 10 bags of 1 KG or 1 long tube containing 10kg of substrait mix?
hello nice video but have one question do you add water to the mix and if so how much
Where do you get the bags... The density of material.. So spawn can protrude through at ease..
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!
We make these column bags ourselves from layflat plastic tubing and seal them with zip zies.

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
Coffee grounds work really well because they hold water. But I am still learning I’m trying to increase my enlightenment.
Would adding rehydrated wood pelletes instead of straw help the mix?
What is the best moisture content using coffe grounds?
In your opinion which kind of mush is used by Ecovative? Tnx
What is the best temperature for growing mushrooms?
I like using a coffee/cardboard mix. All the benefits of straw and can be completely recycled.
Could you mix coffee grounds with pasteurised lucerne pellets?
I watch many of your videos,, and i am searching for the size of syringes and needles you use,, can you let me know ??? hoping for a reply this time,, thank you
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?
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.
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?
Yes it would. I used it when I was a roaster. Straw chaff and grounds.
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.
how would one suggest collecting from coffee shops? im worried about mold growing in the coffee grounds before i get to it to turn intio substrate..
Do you have to poke holes in the bag or do they just pass through as they grow?
Can you please explain why do I need to use the substrate with the coffee ground?
Thanks in advance.
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.
Where do you guys get those long bags from and do you make holes in them so the mushrooms mycelium can breath?
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.
Could you use vermiculite with the coffe to help it be less compact.
Can you add tea to the mix or would that taint it somehow? (like adding sugar to the tea before you take out the teabag)
Awesome! Need to know the best place to buy the spawn. So appreciative:)

👆 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 $
Can you use tea leaves from tea bags as well as coffee grounds?
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.
I wonder if freezing the spent coffee grounds can deter mold some until your ready to mix to grow the mushrooms?
Would it be detrimental to mix several types of substrate?? any experience doing it that way (more than two types of substrate)
Hi guys can you share size if your bags?How much they weigh with coffee spawns and straw? THANK YOU!!!
do you cut holes in the bags? when do you cut the holes in the bags? What temperature should they be at? in the dark?
What about if you were using spore syringes?
Do i need to pasturize the used coffee grounds ?
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?
Hello how are you i live in Torbay a was wondering if o could have a link to the website you get extra long bags from . That I saw in beginning
Hi Elliot, we make those ourselves from lay flat tubing
can I use coffee grounds that used from brewing?
