How to Grow Mushrooms in Buckets! A Step-by-Step Guide

Growing Mushrooms in Buckets! Step-by-Step Guide to the Bucket Technique (Bucket Tek / Tech)
For information on this technique, check out our blog post on growing mushrooms in containers: northspore.com...
North Spore's homepage- northspore.com...
Growing mushrooms on buckets is one of the easiest techniques for growers wanting consistent flushes of mushrooms on a routine schedule. North Spore used this technique to scale from a micro business with a handful of productive buckets to a commercial mushroom farm servicing dozens of Maine restaurants, farmer's markets, and grocery stores.
In this video, we'll show you how to start growing on buckets and scale up your operation if you're hoping to turn it into a business!

Some answers to frequently asked questions! We will continually update this list to answer questions that frequently come up. Q: What species tolerate the high pH growing medium, can I grow x species with this method? A: Any of the various oyster species work well (Pleurotus ostreatus, P. citrinopileatus, P. djamor, P. pulmonarious) as do Chestnut mushrooms (Pholiota adiposa). Lion's Mane (Hericium) does not tolerate a high pH growing media, but can be grown on buckets if you are using hot water pasteurization instead of the lime method. Shiitakes are not suitable to bucket growing and should be grown either on logs (outdoors using plug or sawdust spawn) or indoors utilizing filter patch mushroom bags Q: Can I use the spent straw substrate from the buckets to inoculate more buckets? A: Maybe, though it's not best practice. You can use the spent substrate to inoculate more substrate, however, the more times that you expand a mushroom culture to continue growing mushrooms, the more it will lose vitality and vigor. The process of the mushroom losing its vigor is called 'strain senescence'. You can't continue expanding spent substrate indefinitely, and it's probably best practice to inoculate bucket substrate with high quality spawn. That said, you can get another flush or two from old bucket straw by inoculating an outdoor bed or simply composting the mushroom straw and allowing it to fruit in your compost area Q: What do you do with your lime bath water? A: Lime water is not toxic, but will change the pH of the area where you dump it. We chose a grassy area we didn't mind altering the pH, diluted the lime water with fresh water, and dumped the straw water out. When we do the technique indoors, we dump our water directly into a floor drain. Q: Can the lime water be reused for subsequent batches of straw? A: In our production we always started with fresh water, but I see no reason you couldn't reuse your water bath one or two times as long as you check and adjust the pH (I imagine adding straw affects the pH of the water) and you make sure the water hasn't been sitting around so long that other pH tolerant microbes start to grow. If anybody has attempted this and has insight, feel free to chime in!

wanna know a secret? If you rehabilitate your land back into a productive patch of ecosystem, mushrooms like these will start to grow everywhere. And wildlife will return. And the ecosystem you rely on for every millisecond of your gift of Life will thrive instead of being digested by machines in a far off land that you can't see and don't care about. Separating and isolating organisms from ecosystems is dangerous to the survival of the species, carries diminishing returns in production/nutrient density/soil degradation, and creates an escalating rehabilitation cost vs output value that eventually overwhelms the business model/nutrient requirements of any system you attach it to. Buckets are fun. But ecosystems are cheaper, more efficient, abundantly productive, and are the least we as humans can do to thank whatever we sprang from for the Life we've been gifted. Unanimous scientific consensus says we evolved from fungi. So at the very least, you, me, and every human being on this planet should be responsible for feeding and growing as much fungi as it took for our Life to exist. And really, once you've gone that far why not put enough back to exchange for your children's lives, and the lives of friends and neighbors that you know maybe can't do it for themselves. I mean depending entirely what motivates someone to grow mushrooms like this in the first place. Maybe you don't concern yourself with the equivalent exchange Life demands. That's entirely your right. But that's just another reason for those who aren't sentient piles of human shaped fertilizer to put more Life back than it cost to support them. Because Life costs one equal portion of Life. Your Life, my Life, every microbe, every invertebrate, every bird, bee, and fish. Each Life costs exactly one Life. That's the deal. There is no escaping this reality no matter how many layers of industrialization and consumerism we line the bubble we surround ourselves with. Every Life owns a Life. Are you paid up?

How long does it take to mix the lime and get a consistent pH reading in the big tank? The reason I ask is just because stirring with a big stick looks slow af. Assuming the extra aeration didn't hurt anything, I'd get monster air pump from a hydro store and chuck like 20 airstones in there. You get constant vertical mixing that way.

[@firstmighk]

This is one of THE most informative and actionable videos I've ever seen, and that's across all kinds of subject matter, not just mushrooms. Thank you so much for your generosity in sharing such valuable information! Liked, sub'd, and will def be purchasing my first spores from NS! Dumb question: Seems like inoculating the whole substrate would lead to wasting the spore in the center of the bucket - 1. Am I way off on that? 2. If not, would there be any benefit to say, placing a vertical 4" pipe (or some other space-taking material) down the center of the bucket to make the inoculated substrate go a little further?

[@NorthSpore]

Thank you so much for watching the video and the kind words about it! We put a lot of effort, energy, and time into our videos. To answer your question- mushroom biology works differently from plants in this regard. The mushroom mycelium will colonize the entire bucket all the while consuming the substrate as food. When the mycelium reaches the ends of the bucket and no longer encounters fresh uncolonized substrate, it triggers the fungus to produce mushrooms. In a way, it realizes that there is no more food for it to consume which means it's time to reproduce, spread spores, and hopefully find some more food for the next generation. All of that food in the middle of your bucket that may seem useless, is all converted into fruiting (i.e. mushroom producing) energy by the fungus. The more food, the bigger the flushes and the longer the buckets will produce. Minimizing the substrate held within the buckets would only diminish your yields and the longevity of your buckets. The inverse consideration is that the larger your substrate vessel, the longer it will take for the mycelium to fully colonize it and have that fruiting event triggered and the more likely that other competing fungi or bacteria are able to make their home in the substrate before your preferred species has been able to fully colonize it. There is something of a sweet spot with the size of a 5-gallon bucket. Just enough food for great flushes, but not too much for super slow colonization or risk of contaminants. Hope this helps!

[@noway2451]

22:22 with all due respect to these two gentlemen who are teaching me so much i didnt know but just one idea that came up: if you packed the straw bags into the container and secured them down first with a metal grid and then added the lime solution on top you wouldnt have to surf on them to submerge them. Also you could take the guessing work out of the creation of your lime solution and just measure the water and the lime to get it right quickly everytime. This would also tell you how much water, lime and straw you need which could make your cost calculations more predictable.

[@NorthSpore]

Great idea! I think that would work well, it will just involve more planning and infrastructure. The nice thing about weighing down the lid with the cut off top of the IBC tote is the simplicity and ease of sourcing and working with the IBC totes.

We're committed to making mushroom growing accessible and open sourcing what we've learned. We keep our business going by selling spawn and helping people find success!

Do you have any best practices for cleaning your buckets? I am trying to target restaurants as I feel I could scale easily as I add customers -- do you recommend sticking with a single type of oyster at first or diversify from the beginning? Is there a type of oyster you saw as the most sought after for restaurants?

We definitely prefer straw! I'm not sure exactly how many buckets that recipe will fill. Starting with a mix of oysters is fine, but blue oyster as the bedrock is the way to go.

I must admit that we aren't compost experts, but I don't think the final product would have a super high pH. As things compost, it it will move towards neutral. Especially with other ingredients, proper hydration and turning, I have no doubt this would make great compost and attract the right microorganisms.

could newspaper and pine wood shavings work in combination? I'm just beginning to think about how to grow mushrooms, I've heard pine and other conifer woods have anti-fungal properties them, would using pine wood shavings be counter-intuitive? The newspaper I'm thinking of using uses food-grade ink, but again how food safe or viable is that, since I've heard mushrooms absorb whatever substrate they grow from.

[@NorthSpore]

I think you'd be likely to grow mushrooms, but I would also be hesitant about eating anything grown off of treated materials like newspaper. Pine shavings can be tolerated by some species, but usually only when they are mixed with some type of hardwood substrate

I always thought you had to put the Hydrated Lime into water first, then add that to the substrate. Mixing the lime right in provides the same outcome? Thanks!

[@IkeOzurumba]

Amazing video! I find mushrooms so fascinating. One question I've always had is, how does the size of the bucket/substrate relate to yield? Why a 5 gallon bucket over a 1 gallon? And if more substrate equals higher yield, why not go bigger bucket? As far as I understand it, once the colony runs out of food it fruits. So does the size of the colony when that happens equal a higher yield? And ia it not worth it to go too big of a bucket because it takes to long to run out. So many questions hahhaha. Thanks for the awesome video! Please keep em coming.

[@UmamiPapi]

More substrate or more nutritious substrate is (generally) more yield. I imagine 5 gallon is a sweet spot for workability, since you still have to carry it around. And as you saw you just stack them to scale up. One gallon wouldn't grow much and larger would be hard to work with. 5 gallon is also easy to source, like they mentioned getting them free or cheap.

[@NorthSpore]

the larger the amount of substrate, the slower the colonization process will be and the greater the risk of there being areas within the substrate that go anaerobic and contaminate. As Umami Papi stated, the 5 gallon bucket is a sweet spot for workability. The buckets are plentiful, made in food grade plastic, and are easy to work with. With that said, you can certainly inoculate larger or smaller vessels.

Do you test to find out if the kiln dried straw you're using contains persistent herbicides like Grazon?

[@NorthSpore]

We don't

[@urbanmealwormsfarming]

Liked. Awesome video and explanation

[@NorthSpore]

thanks for watching!

[@Nevernottrying]

Thank you for the very informative video! Wondering what the reason for placing the rocks on a bucket lid, rather than placing directly on the bags?

[@NorthSpore]

The rocks are to help hold the lids in place.

[@PlantObsessed]

Out of curiosity do you know the pH of the water after the straw was removed? Could the water be used for more than one set?

[@NorthSpore]

I'm unsure. I imagine it would move more towards neutral pH but probably still be pretty basic. You may be able to use the water bath another time if you check its pH and amend with more lime if needed, though I will say the straw water gets pretty gross quickly. After one 'bath' the water will look like dark tea.

[@dennisfarris4729]

​@@NorthSpore I'd expect it to be a nutrient-rich solution which once ph balanced should be amendable to hydroponic application.

[@JoaoVitor-pj3uk]

After adding hydrated lime to the substrate, should I wait some time before adding the mushroom spawn?

[@NorthSpore]

Yes, it might be overkill, but we recommend soaking the straw overnight, draining and then adding spawn as soon as the bags are drained.

This is definite interesting and pleasant to watch. Although I won't go a big scale as you do, but still fun to watch. Question: how many flushes you often get from a bucket? Thanks for sharing?

[@NorthSpore]

Thanks for watching! We would keep our buckets for three flushes of mushrooms then empty them outdoors. We'd often harvest mushrooms from our compost heap (for our own consumption) in the cooler days of early spring and late fall!

[@farmer_T]

@@NorthSpore Thank you so much for quick response. I learned a lot from your videos, although I grow in buckets also. I also you guys didn't drill holes at the bottom. Probably the reason is you have drained material very well. Cheers.

[@luqmanhkm2960]

can we use the used straws to as a spawn for the new batch?

[@ahosie]

Absolutely fantastic guide. Thanks guys 👍🏻

thank you for sharing your knowledge!

[@NorthSpore]

thanks for watching the video. Think you'll give it a try?

[@sharimottram8266]

I currently have pink oyster growing in straw in garden. And waiting on winecaps in another area of yard. I want to start maybe blue oyster in buckets. Is there a bad time to begin this? I am in zone 6, and have a good 2-3 months of warm weather left. I also have a good garage or basement if needed. Thank you

[@NorthSpore]

Never a bad time for blues!

[@joylefevre7288]

What do you do with all of that water that you have added the lime to after you soak your bags? Do you filter and reuse any of it or do you allow it to evaporate and reuse the lime?

[@NorthSpore]

Lime water is not toxic, but will change the pH of the area where you dump it. We chose a grassy area we didn't mind altering the pH, diluted the lime water with fresh water, and dumped the straw water out. When we do the technique indoors, we dump our water directly into a floor drain. You probably could evaporate it and reuse the lime if you are patient!

[@TheZGALa]

Thanks! Great stuff. I look forward to trying this.

[@NorthSpore]

you should give it a shot! thanks for watching
