Spray Painting bottom vs. Trash Bag Liner- consensus is that using the contractor/trash bag liner method is superior to the spray paint method shown in the video. As the substrate colonizes with mushroom spawn it will pull away from the sides of the tub (as shown in the video at 21:27). When this happens microclimates form that will cause mushrooms to grow along the sides. If an opaque trash bag is used to line the bottom part of the tub the bag will pull away with the shrinking substrate and minimize these microclimates.
Drilling the Holes in the tub- Reversing the direction of the drill will minimize any potential of cracking the tub. The friction of the hole saw will burn the hole through the tub.
Polyfil and Location of Holes- putting the holes 1 inch above the substrate seems to be ideal and less polyfil is needed then demonstrated in the video. The end holes should be slightly higher than the hole sides to help with airflow. There are plenty of alternatives to polyfill including micropore tape. Plenty of other ideas (none of which we have tested) have been suggested in the comments.
We use the word 'sterilize' in the video when we should use the word 'sanitize'. You're never going to make the process completely sterile, but you can inhibit microbial activity by sanitizing all your materials and your workspace using alcohol!
A warning about using Isopropyl! Isopropyl alcohol and its metabolite, acetone, act as central nervous system (CNS) depressants. Poisoning can occur from ingestion, inhalation, or skin absorption.
The needle coming out of the package should be sterile, but it is standard practice to flame sanitize after opening. In our laboratory we use an alcohol lamp that won't leave any carbon residue.
The fan intake filter came with a filter on the outside of it. At the point in the process where you would use the fan (once the tub is fully colonized), there isn't much risk of contamination. We've tried setting up the fan to exhaust with success too. Don't use the fan during your initial colonization period!
Ideal temperatures for colonization/fruiting will vary depending on species and strain. Check the specs on any liquid culture/lineage of the spores that you're using. Usually the hotter the temperatures the faster the colonization and fruiting but the more prone to contamination by mold. Certain species require cooler temps! - Věda a technologie
Pro Tip: instead of the PC fan blowing air into the box, it should pull old air out of the box. This will force air to be pulled in through the poly fill where it can be filtered. Otherwise blowing in unfiltered air renders the poly fill useless.
i like that
Went to the comments for that specific reason. He was so adamant about sterilizing everything and taking about the poly fill filtering out spores and unwanted stuff, then mounts the fan pointing in with no filter.
I was going to say the same thing. The purpose of a vent fan is to push old air out and bring new air in through the filtered holes, which I believe should be located lower than the fan around the tub.
@@jdsr4c c02 is heavier than air, co2 is what you want to remove. My logical thinking would make me place the air holes higher and the fan lower. Making the fan able to directly blow out c02 instead of having to "pull" c02 up first. No?
Don’t think you’ll run the fan until fruiting stage and the mycelium is pretty resistant at that stage.
I’ve been addicted to heroin for 11 years, but after trying out psilocybin treatment I will be 2 years clean.
Congratulations, that's fucking huge and you should be proud. ❤
Congratulations!! That’s amazing!! Keep it up!!
Holy fucking shit man. That’s stunning, super proud, keep it going, so glad you found your way ❤️
I would like to get off methadone using Psilocybin, but I would be treating myself obviously and do not have any idea how to go about doing this?
@@justinhayes2194research it? It’s not illegals to look up information
Several things within the first minute that might help you out 1. Get air in the bag so mycelium can breathe and spread faster. 2. When injecting spores, move the needle around to cover more area as it tends to colonize faster. 3. Shake that syringe vigorously for 30 seconds as spores tend to clump together. Separating them tends to offer more opportunity for more surface area. Happy growing✌️
Good advice, thank you!
how would you get air into the bag without contaminating?
Number 3 should be number 2. First shake, then inject :)
I have no idea and have not even started but I seen bag with vents. For CO2 exchange. His bag does not. Confusing. So getting air in there as you said seems required.
@@hou7707 the grain bags tend to have almost a medical fabric pad on the upper side of the bag that is where the air comes in. When mixing unfold your bag & you will notice air will come in as you GENTLY shake the grain upwards. also dont fold the top back down let it stay unfolded I have a UV Air Purifier close by as well. Good Luck Ren!
hell ya
I’ve never grown mushrooms before hence why I’m watching your video. I DO have a LOT of experience drilling brittle plastics. There are two ways. First is easy, DRILL IN REVERSE. The heat of the friction softens the plastic and gives you a nice smooth cut hole. Option two, use a warn out hole saw, or use a gritted diamond blade. I’ve used these methods on the same tubs for other projects (I am a professional builder and inventor. I have made terrariums for clients raising psychedelic reptiles and amphibians, grow boxes for rare swamp cultures, so on. Give it a shot and tell me your results. ) Happy Harvesting!!
Absolutely wonderful advise. The same technique works for hydroponic cloning tubs, as well.
@@adambugher4837 same advice works for hydroponic kratky tubs with rubbermaid 10 and 20 gallons then i use a pool noodle cut into 1-2" sections (with a slice down one side to insert the plant) to hold the plant in place. Learned this from kratky videos and Mike Dunzee growing channel.
I made a mono tub today, and found that using a blunt hole saw definitely works really well
You can't just bring up psychedelic reptiles without explaining what in the fuck that's supposed to mean
@@dogbless9306 yeah 🤣🤣🤣🤣🤣 what he said
Here's a tip... When drilling holes, reverse the direction of the drill in order for the friction to burn a hole through the tub. This drastically reduces the risk of cracking your tub. You can apply more pressure, which increases the friction to bang out the holes faster and you still won't crack the tub unless you're being extremely careless.
Also a good suggestion!
*Pro tip
Or heat a nail. Or better yet, a half inch pipe.
I came here to suggest the same thing, I've drilled holes in plastic a bunch, and in reverse is the way to go.
Made similar comment before I saw this one. So I second your opinion.
This dude is the best, he explains everything so well. Doesnt ramble on but gets to the point while still being thorough
Good job duder
totally AGREED!
I’m just getting into shrooms. My gf has chronic illnesses and I want to grow lions mane in addition to many others for the health benefits and we just love eating mushrooms in any dish. I love the mushroom community so far. Everyone seems so wholesome and knowledgeable. Can’t wait to get more into this culture… Pun intended. 😅🍄
You got this! Keep the passion going.
Something I've learned from other videos and research is to place the side holes lower and the holes and the short end higher up. With poly thicker on the bottom and thinner at the top holes creates airflow due to weight differences between the air and Co2
Edit: if you use a hairdresser spray bottle it will give you incredibly fine mist.
Thanks for the suggestion!
Microphone tape works better in my opponion
Does the water in the bottle need to be sterilized? Bcuz without it would have contamd
Never mist, never open your tub, nail your FC perfectly and you will never need to risk contamination by spraying.
@@ThatGuy-ul4nx honestly yes if your FC fruiting chamber is dialed in good then yeah.. some places can b drier climate etc, with.monotub should work jus fine tho. I like using tyvek instead of polyfil for the holes. Misting doesn't contaminate it though. If your substrate is fully colonized, then it's pretty dam contam resistant . I've had substrates on the dirty floor and got rflushes
A small tip to take a better look during that first few weeks; put a bit of cloth between two magnets, one inside, one outside and you can wipe away some moisture to make a window (y)
That's a great idea! Thank you.
I agree, I’ve made numerous containers for hydroponics and it’s recommended to reverse. The other comment is undoubtedly a lack of education.
Legend maintains that no matter what time you read this he is sterilizing something somewhere.
It's the truth!
Remember to really get in there
He is... the most sanitary man in the world
make sure to massage that bag
they alcohol doesnt negatively effect the spawn or substrate at all? i know some people use water with hydrogen peroxide does it make a difference?
A tip when drilling the holes is to actually use the holecutter in reverse to help prevent cracking the tub
I was going to say the same thing lol. I've had to cut plastic many times, and often enough you do need to run the drill backwards to prevent cracking, or chipping etc
or just burn it. he clearly buys better quality plastic containers than you. not everything is walmart grade plastic.
Black craft paper instead of spray paint seems a way to make the container dark too. That’s especially helpful for HSPs.
i use rainbow wallpaper myself- that way I can sell the strains as "inclusive" varieties. gotta start when they're spores or they just come out regular.
Most detailed monotub walkthrough I've seen yet. Awesome job guys. Thanks a bunch!
Thanks for watching it! There are a number of great suggestions from viewers in the comments too
And now it doesn’t show up in CZcams’s search. Weird huh?
...shrooms or mushrooms
look up Willy Myco for advanced tek's
I tried to grow Portobello mushrooms from a spore print back in college, and ended up with a tub of green mold coffee grounds. This video was quite an eye opener to how little I actually knew!
Glad to give you a little refresher!
@@NorthSpore it was not about you. it was about the video. so you are glad that the video gave him a little refresher.
@@emmagrigorian5822 He made the video?
@@mightybrake4850 some of these people man 😂, they need to chill out on the shrooms.
Very informative, thank you. My Father cultivated but I was to stupid to ask him for tips before he passed. You have a new dedicated subscriber now. Look forward to putting these lessons to the test. Bless you guys.
We're happy to help!
@@NorthSpore Stupid question and I know this is an old video, but using this process, how long can you keep your mushroom factory ''alive'' until you have to redo the whole thing? Will they just regrow themselves if you take care of their needs or do you need to inject ''new blood'' so to speak after a while?
Great video also!
To help prevent cracking, place a layer of the tape on the tub before drilling and then drill through both the tape and the plastic. A better solution to stop the plastic from flexing/cracking, is to place the tub on a firm surface such as work bench or scrap 2x4 and drill directly into the wood. Both of these methods will help, but the key factor, as you mention, is to keep your pressure light and go slow. Thanks for a great video. Your emphasis on sterility was something I wouldn't have given much thought about.
The best way is to run the drill in reverse.
@@FullCircleTravis I was going to comment that exact thing. Never had a crack when running in reverse
Just what I was thinking it's the way to go the bit won't bite in it melts through the plastic making a clean hole
I don’t drill at all, I just use a thin metall pipe or a warn out hole saw with the size i want that I don’t use for drilling anymore. Heat it up with a torch and just push it through slow by melting the plastic 😊 Smooth clean holes every time and no mess. (Do it outside to prevent breathing in the smoke of the melted plastic)
@Joakim A stencil cutter that uses heat much like a soldering iron is good for cutting some plastics. As with the alcohol, there could seemingly be toxicity issues. I would think a high alcohol % grain alcohol to sterilize would be much safer (such as vodka or Everclear), as rubbing alcohol is toxic when ingested.
It depends on the plastic type used, but yes! Don't breathe in plastic fumes.
I'm thinking glass is a better container for the substrate, especially when there is BPA and other hormone disrupting chemicals (HDCs) in many plastics.
Good stuff. Thank you!
A pro tip for drilling holes with a hole saw in the totes: Run the drill backwards and you will never crack them!
Thanks!
Just make sure you start the pilot hole with the drill going "forward"
Nice tip. This will save a Massive amount of plastic :). Good job
@@danielengsvang3126 or you can heat up a soup can and hot punch them. No cracks or burs.
Can confirm, this works with hole saws as well as paddle bits. It prevents the blade from biting into the plastic.
Hospital: "We've just sterilized the whole place!"
North Spore: *runs finger across floor* "Yeeeea, I don't think so"
hahahahahaha
Does anyone know what the stuff u inject is how do i buy it whats it called?
cxed spores I basically shroom seeds
Lmao
@@THIRTEENTH13TH ive seen tons on etsy but i havent ordered yet, i ordered colonized substrate from amazon will start tomorrow
Fellow Mainer here, I live in South Portland / Westbrook area! I was watching this video and I knew I recognized the building when you went outside, what a trip! Awesome video.
Helpful tip when drilling your air holes, hold a flat piece of wood bigger than the hole you intend to make on the opposite side. This will give you a cleaner hole and reduce the risk of cracking.
reduce it entirely by just heating a drill bit. nothing a little duck tape doesnt fix anyway.
Some updates! Here are a few top suggestions from the comment section. We'll keep updating this as more information comes in:
Spray Painting bottom vs. Trash Bag Liner- consensus is that using the contractor / trash bag liner method is superior to the spray paint method shown in the video. As the substrate colonizes with mushroom spawn it will pull away from the sides of the tub (as shown in the video at 21:27). When this happens microclimates form that will cause mushrooms to grow along the sides. If an opaque trash bag is used to line the bottom part of the tub the bag will pull away with the shrinking substrate and minimize these microclimates. The one downside I see of the method is the increase in plastic waste. We've never had issues with side pinning or losing mushrooms using the paint method, but we don't use monotubs for our commercial edible mushroom production (we use bags in climate controlled rooms). I agree that if you were doing this at scale (more than one or two tubs) it would be better to use the liner method for ease of cleaning / marginal improvement in yield and ease of harvesting.
Drilling the Holes in the tub- Reversing the direction of the drill will minimize any potential of cracking the tub. The friction of the hole saw will burn the hole through the tub. I haven't tried this yet myself, but it's shown up in the comments a few times.
Also, using a heated can to melt the holes has been popping up in the comments.
Polyfil and Location of Holes- putting the holes 1 inch above the substrate seems to be ideal and less polyfil is needed then demonstrated in the video. The end holes should be slightly higher than the hole sides to help with air flow. There are plenty of alternatives to polyfil including micropore tape. Plenty of other ideas (none of which we have tested) have been suggested in the comments.
We use the word 'sterilize' in the video when we should use the world 'sanitize'. You're never going to make the process completely sterile, but you can inhibit microbial activity by sanitizing all your materials and your work space using alcohol!
70% isopropyl is better than 90% . The water content in the 70% isopropyl solution helps in the sanitizing process.
A warning about using Isopropyl! Isopropyl alcohol and its metabolite, acetone, act as central nervous system (CNS) depressants. Poisoning can occur from ingestion, inhalation, or skin absorption
The needle coming out of the package *should* be sterile, but it is standard practice to flame sanitize after opening. We use a cigarette lighter in the video because they are easy to obtain (and work), in our laboratory we use an alcohol lamp that won't leave any carbon residue.
The fan intake filter came with a filter on the outside of it. At the point in the process where you would use the fan (once the tub is fully colonized) there isn't much risk of contaminations taking over your tub. We've tried setting up the fan to exhaust with success too. Don't use the fan during your initial colonization period!
Ideal temperatures for colonization / fruiting will vary depending on species and strain. Check the specs on any liquid culture / lineage of the spores that you're using. Usually the hotter the temperatures the faster the colonization and fruiting but the more prone to contamination by mold. Certain species require cooler temps!
North Spore I concur with everything you have here with one possible addition. I used some micro filter discs from a popular competitor of yours, normally used on canning jars with lids for air flow during colonization of grain, instead of polyfill. It’s still excellent air flow filtration but doesn’t seem to fluff out so much, making for cleaner lines, so to speak. Plus, the filter discs can be run through a pressure cooker for sterilization and reuse. It’s worked well for me and I live in the desert in central New Mexico. Just suggestions. I only found your channel about an hour ago with the monotub. I like the way you think! I wanna grow more, expand to supply the local garden market. You’re proof that it can be done!
North Spore another question please: growing in summer temperatures of 30-35C (86-95F) with fairly high humidity.... is this a problem?
Nick Anderson paddy straw shrooms grows at that temp. Look them up, otherwise you will experience contamination hell
To prevent contamination you should also wear a surgical mask, maybe a hairnet. I suppose the water in the spray bottle should be distilled water or purified water, because there are micro-organisms & chlorine in tap water
You can use drill in forward direction safely and without cracking tub, just put a flat, thick enough peace of wood that wont let drill pass through quickly and press it from inside of tub (2cm is about enough)
I love how you replied to almost every comment
There's been a bunch of great suggestions, hoping the comments add to the video
Got my tub, my spawn bag is almost completely white!!! Super excited to get to the next step! Thanks guys.
Send it!!!
how’d it go? thinking about getting myself a kit!
How did it go? How long after the initial culture injection do you massage the bag again?
> at home technique
> positive pressure flow hood
Lmao precisely
lol
Jokes aside, a flow hood is actually pretty simple to build yourself and not ridiculously expensive. Tons of guides online for them.
Just use a still air box. If at first you don't succeed. Try again. It just takes a few attempts and providing you're rigid with your technique your confidence will soon grow. Saves for hundreds of pounds and really isn't much hassle once you realise that the technique, when done correctly, works
It's certainly not necessary. We debated about using it in the video or not. Ultimately we wanted to convey the importance of doing the process in as sanitary a space as possible.
I feel like this can only be done really high at 3 a.m.
currently watching at 2:35 am
True
You never know when inspiration will strike!
3:41am close enough
2:15 a.m.
This was so incredibly helpful. I have wanted to try growing mushrooms myself for a while but my adhd always makes me believe I can't but this was so so helpful. Thanks.
Awesome, we're happy to hear that!
Your doubt holds you back 😉 grow hard, dude
99% of people diagnosed with adhd, do not have it. Its all about the money.
keep on growin' all! Fantastic people taking charge of these opportunities
Boy, he's really getting in there!
A clean environment is very important!
Me: will never do this
Also me: emotionally invested in this video and channel
You can do it! But thanks for the emotional investment!
It's awesome how inexpensive and accessible you guys are making it to grow your own delicious mushrooms! I've been trying to grow more of my own food, but have always had problems with space living in a small studio apt. Eventually I'll upgrade to a grow tent with some lights and then I can start growing a wider variety of veggies!
Love that you added the high speed/little pressure tip for the hole saw part! Lots of folks dont know that! A good way to save drill bits too ✌🏽
If you're wearing out hole saws drilling through plastic, you have bigger problems... A sharp hole saw run in reverse after setting the center hole in fwd will never chip or grab while boring holes in thin plastic
i don't even intend on growing shrooms, but this was so entertaining to watch from start to end.
glad you enjoyed it!
I feel like this is the only video I need to watch to know how to grow mushrooms. He chose good products, nothing you might feel is too expensive or too complicated to operate. He explained everything very well and showed it to give you a clear idea of what things are supposed to look like, and with how sterile he was with the alcohol and how through he was at explaining everything from material to process I'd say i feel pretty confident in doing this myself.
Thanks for your support!
How did it go
Same! This video was the final catalyst for me.
Soooo do I have to use all substrate for it? Can I use my own human substrate?😂 cause I'll harvest if it it actually works🤣

Best video I've seen to date. Incredibly helpful with clear instruction. I ended up buying your Boomr Bag Monotub Mushroom Grow Kit. Thank you!
Hey do these mushrooms need light to grow?
After about a month and a couple weeks, I finished growing my mushrooms using this method. It works well! Thank you for this video demonstration it was super helpful.
Thanks for the update!
Instead of risking cracking my tubs I put an empty tin food can on the stove, get it hot, and push it through the tub.
So many great suggestions for cutting the poly holes! Thanks.
Or use a piece of wood on the other side of the plastic when drilling.

Tyann where do you order your stuff from and whats a good way to start for a beginner
You just saved me 30 or so bucks 😅
Thank you!
I'm late to the party but glad as hell I started the journey. Your content is informative and has helped me get started!
The products I ordered held up very well. I am currently just about ready to case my first tub, the second spawn bag I did one mix on vs two so its colonizing slower but still steady. Going to leave a review on the website soon but I will be returning for future purchases and recommend them wholehearted! I'll be doing a few logs this year and definitely will be getting my additional supplies from you guys. Thank you for the video it was very helpful!
Edit: when you buy a tub don't make a mistake I made and get one with a red top. It makes it annoying if you want to take pictures or time lapses
Your support is mush appreciated!
You have a next level understanding of the grow process. You're helping countless people, and saving lives.
Happy to be of service! Reach out with questions anytime!

Hands down the best video on the subject. Thanks very much.
Thanks!
Just a small thought:
I've recently experimented with liners/paint.
The tubs I used a liner on had 0 side pins.
The tubs I didnt use a liner but painted on had tons of side pins.
Upon researching why, I learned that as the cake shrinks it developed the ideal microclimate for mushrooms to form on the sides.
The point of a liner is that it sticks to the sides of the cake as it shrinks not allowing this microclimate to form.
Thanks for sharing your experiment. Paint is just one option to black out your tub, a liner is another great option and can help with unwanted side pinning as you observed.
Exactly, this paint suggestion is painfully naïve and does nothing to address the microclimate introduced by the fully colonized sub pulling away from the bin. When you use a liner the sub attaches to the liner and pulls it with it, putting the gap on the other side of the plastic and eliminating side pinning. That's when I tuned out on this vid.
Thank you for this suggestion. Do you just mean the typcial HDPE black liners you would use for drainage for ex?? First timer researching and trying to find the right set up! Thank you for your experience/experiment and sharing
@@ManGo-mu5rd hopefully you already found the answer in your research but a black garbage bag works best. Not the thick, good contractor type ones but the thin dollar tree kind.
@Hayley you're cutting the bag? Single layer that fits about half the depth of the bin?
I'll try this with some straw instead of the boomr bags since i'm kinda broke but the technique itself seems flawless! Thanks a looot.
One tip with working with plastic is if you got a torch like oxy or even just propane heat up your circle or hole tool and you can melt your hole in the plastic and it’ll prevent cracking. I’ve found it really depends on the type of plastic. Clear and white can be brittle and sucks to drill but colored and more thick and more of a rubber feel I’ve found it doesn’t crack like the clear plastic
Heat up the top rim of an empty soda can works nicely
Best video I have ever seen. The editing too! NICE
Thanks for watching!
I've watched a 100 videos on this subject, and so far, this video is the best.

I love this video. Thank you for including the written walk through and materials used.
Seriously, so helpful in every way. This video is a staple!
Thanks for your support! Let us know if you have any questions!
Thank you so much for walking me thru this.
Thanks for your support!
I have watched this video several times as well as a couple others on the subject. I have been purchasing the materials/equipment for this project and have the following observations, comments and requests for comment:
1) I live in the high desert, and so have special concerns about the amount of humidity that my mushrooms receive.
2) I have purchased a small reptile enclosure sonic humidifier for my Monotub which I will control with a humidity controller.
3) The 4" inline fan that Northspore is selling for use with a Monotub moves air thru it at 129 cubic feet per minute (since the fan specs list the air flow at 220 cubic meters per hour) at full power. If the air replacement inside the tub didn't mix, the fan would replace the air in the tub every 1 second. The mushrooms don't need this and the humidifier won't keep up. Yes, there is a speed control, but I suspect it won't work well. The video does show installation of a computer fan. The very smallest fan of this type that I could find replaces the air in the Monotub once every minute..... so it needs to have a short period timer to use this small fan.
4) Should we use the fan to blow the fresh air into or out off the enclosure? The discussions on this video appear to center on the desire to blow air out of the enclosure because blowing air into the enclosure would introduce contaminants that could threaten the mushrooms.
In viewing the Martha Tent video, Northspore (and others in the mushroom community) is concerned with allowing spores to escape the enclosure. My understanding is that spores can make a mess, can be harmful to our health, and can even start mushrooms growing on wood elements in your home (like wood house framing members). Their system sucks air out of the Martha enclosure and either filters it or blows it outside the home. This negative pressure system allows replacement air to enter around the bottom of the tent which is, of course, not filtered and possibly full of contaminants. Apparently, during fruiting, the mushrooms are not at much risk from these contaminants. I am therefore more concerned with keeping the spores out of my house.
5) It appears that the simple way to address the concerns listed in 3 and 4 above is to use a very small computer fan on a short period timer, and blow the air into the Monotub enclosure. The air would escape through the filtered holes and through the humidifier (unfortunately unfiltered), or... blow the air out of the enclosure with a filter installed at the small fan, or... somehow put the little fan inline with the humidifier... I am looking for ideas and comments on this thought process.
Thanks for any ideas/help with this. John in Flagstaff, AZ
I have a big suggestion: Don't modify your monotub. It's a beautifully passive system and modifying it usually just creates problems. If more humidity is needed during fruiting, it's easier to just mist a little with clean water. The inline fan we sell is for the BoomRoom or larger grow chambers. We prefer to blow air and spores out and pull fresh air in from the bottom edges (negative pressure), but positive pressure works too.
@@NorthSpore Thanks for the heads up. The place in my house that has high enough heat is the boiler room with less than 20% relative humidity. I was planning on humidification with a small reptile model with controller, and a 2 cfm computer type fan. Humidifier blowing in and fan blowing out on a short duration timer. I plan on installing a filter at the little fan. I will monitor the humidity and temperature with remote weather station sensors..... I am an engineer who lost most of my first oyster grow kit to lack of humidity.... I am sure I will make corrections as I go. Thanks for your response!
Usually simple is better! Some videos that I have watched all seemed to generate mushrooms with small caps...... too much CO2 was the message. Do you have experience with monotubs in the high desert?
Highest quality n most informative I've seen yet

I was actually going to buy a mono tub from North spore but after watching this, I think I will make one and just use them for my book substrate. Awesome video.
Honestly that makes a lot of sense. You can make the tub easily, but the substrate is much more difficult and very important.
Hey man I’m from Maine so cool getting a tutorial so close to home
The way life should be!
Can you do a video on how to use the spent mushroom substrate to start an outdoor bed?
yes !
We have a video on how to try for round 2 with our Spray and Grow Kits that could be applied to your spent monotub cake! northspore.com/blogs/the-black-trumpet/what-to-do-with-your-mushroom-grow-kit-when-its-done
Just ordered my growing supplies let’s see how it goes! I’m excited
Let us know if you have any questions!
This is great! Thanks for doing this. Could you make another video with the upgraded mushroom results so that we can see the difference?
Thanks for your support! We may release an update in the future!
You rock dude that was the most informative vid ever.
Thanks!
🍄 Thank you so much for this video walkthrough. I just transplanted the grain spawn into your brand monotub kit and crossing my fingers that i dont get contaminants. As a first timer, im very excited to see the results. 🧑🔬
How did it turn out?
How did it go?
How did it go bro?
how'd it go brotendo?
Bro let’s us know
Thank you..I REALLY want to start growing mushrooms
Watched this at least 10 times over the past year, finally got it done last night. Such a helpful video and y'alls customer support on Instagram is thoughtful and friendly. Really appreciate the company and the resources your provide. Much love
Awesome! Thank you!
Ty for getting all in there
The drying advice was psuper helpful! thanks!
Reach out with questions anytime!
Hands down best mushroom growing video. Going to be trying this out soon! Thanks for the great info!
Mush love!
Ty for making this awesome video!
This looks really comprehensive! Thank you sir!
Thanks for your support!
When he starts the time laspe you can see how the mycelium is breathing like lungs from the condensation on the bag :) it's so cool!
The whole process is so interesting and fun.
I did it maybe this is my calling. I'm going to try
This is a lot of great information. I ordered two bags of grain spawn, would love to connect with you guys.
Thanks for your support!
Best video on this subject by far
Thanks Ian, it was quite the undertaking!
Not really lol
@@robertyoung8871 wheres the better one then? . . .
@@robertyoung8871 Yes please enlighten us master Tang-Wu. Your fruit growing skills are remarkable.
Amazing video! Just to put my two cents, run your hole saw in reverse as others have mentioned! Hope to buy some of your products soon and start growing my own culinary mushrooms both indoors and outdoors.
Tthis is what I'm looking for . Thank you very much.
Just tried this tek complete with the pimped out add-ons, a few suggestions to would-be growers if interested:
First tip is to buy North Spore's grain/substrate if you're a first time grower, the grain colonized really quickly and the substrate produced a great couple flushes of agaricus bisporus, some of the best I've ever had.
Use 2 spawn bags instead of the 1 they suggest here, I got a great yield but it was really uneven bc the substrate didn't colonize uniformly throughout the cake. Pinning started before full colonization, despite my best efforts.
It's probably easier to run the fan and the fogger manually based what the conditions are, provided you have the time to do this. Those humidity sensors don't work so well at high humidity, and the fan will run too frequently if you're using the cycle timer. I ended up running the fogger 3x a day for 20 minutes each, and the fan for a couple minutes 3x a day with the lid slightly cracked for better airflow.
Cover the fan hole/screen when you're not running the fan and when you're fogging. Too much moisture was escaping through the hole and my cake would dry out pretty quickly, and covering the hole solved this problem.
As others have suggested, use a black trashbag instead of painting the bottom. It'll provide better side pin prevention by both blocking light and preventing the sides of the cake from getting oxygen, since the bag will stick to the cake when it contracts so fresh air won't touch it.
Fantastic suggestions! Thank you for taking the time to write this out and we appreciate your support.
This helped me a lot. I'm about to try buy a right kit and grow for the first time!!!
Do you put the bad inside the tub then?
Great video! Can't wait to get started. My first attempt was not the best but I learned a lot for the next time. I really loved just how energetic I was after eating fresh oyster mushrooms.
If you don't mind me asking , what was not ideal about it? Any contam ? Asking because I'm considering doing it for the first time soon.
Glad you weren't dismayed! Keep trying. You'll get better at it!
@@kevinanderson9752 sorry so late on the response. And yes the sanitation is a must! I got a good first harvest and then I tried to innoculate a second time but I wasn't as careful. So it got contaminated. I'll be trying again soon! The energy is amazing and I'm wanting to feel that again!
This is great, its exactly what im looking for!
Awesome Video! Very informative! Thank you! 😊
Glad you enjoyed it!
This is an awesome video thank you so much
Glad it was helpful!
Great video! Super informative. pro tip: remove tape while paint is still wet for clean lines.
Nice tip! Would have looked better.
Also Pro tip - Use some unrecyclable paper from the tape *upwards* to avoid paint spray-over (the little flecks above the tape line.)
this is a great and instructive video
Yes, another video shedding light on going from all in one grow bag to tub. So basically, I'm already in good shape at day 6. I can't contaminate my spawn mixing into my substrate unless I wanted to. At a certain point, I'll mix the mycelium and substrate from my all in one bag together and with sterilization and then GO STRAIGHT INTO THE TUB. That's awesome. I'm going to top/case/frost with coco and vermiculite, but no other video has had these visuals and instructions and I APPRECIATE IT dude. lmk if I'm wrong, but this hobby is starting out to be mad easy and I love it
Recognize that this video is a little dated and we've added to is on the walkthrough on our website. See that here: northspore.com/pages/mono-tub-cultivation-method-walkthrough
@@NorthSpore thank you 🙏 I'll read up
edit: I like the updates, thank you I will forego the vermiculite in my casing and update my notes!
Can you use this method for magic mushrooms?
Very informative.
this is th ebest video on this subject ive seen so far
It has it's issues, but thank you. We're hoping to make a new one soon!
Run your drill in reverse to etch the plastic cutting it slowly. Works great on house siding also.
Been researching a lot because I LOVE mushrooms and want to grow them. I put them in all my food dishes. What’s funny, I already have a LOT of substrate since I own tarantulas. 😂🤣 So I guess I can check that off the list. Once I get paid definitely buying a kit so me and the kids can grow them. Then once I’m more experienced, I’ll upgrade. But this is so very helpful.
Awesome! I'd love to see some tarantula x mushroom content come from this.
@@NorthSpore I mean random mushroom's do grow inside enclosures sometimes haha
❤much love thank you
From a carpenter standpoint, if you will put a solid wood board/block behind your tub as you drill you will run less chance of cracking/breaking the plastic.
I don’t see why you couldn’t heat up a hole saw or something similar and just push it through the plastic
Wow, so much great information!!
So happy to share!
To prevent it from cracking just run the hole saw in reverse. That’s a good technique used to put lights into thin soffits in a house.
or just use a soldering iron instead.
Thanks!
"Other types of mushrooms in tubs will enjoy a casing layer as well."
It all depends on the species!
A lot of oyster farmers out there
