Mushrooms
Posted by kandm1983@reddit | preppers | View on Reddit | 74 comments
I just had a thought. Mushrooms seem like they’d be a great prep. Easy to grow. Very quick turnaround from spore to harvest. Canning materials can serve a dual purpose. What are your thoughts? I haven’t seen it mentioned on this sub. Maybe it has.

Mushrooms are nice as an add on but by themselves they offer pretty much no nutritional value. They have flavor and anti-oxidants. But almost zero carbs/fats or protein. So they have pretty much nothing you need for survival.
Smedley5@reddit
This - in a prep situation they aren't adding enough calories.
Time_Savings3365@reddit
They aren't high in calories, but good for minerals. Selenium being one of them. It's an important mineral that your body needs.
Puurgenieten89@reddit
But they add flavour and trust me as a poor student once eating the same meals day after day gets mindnumbingly annoying yes prep the food but dear god get herbs and spices are a must
silasmoeckel@reddit
Micro greens and herbs are easily grown. Mushroom's flavor is nice but nothing else there.
thomas533@reddit
Microgreens require good lighting, either natural light or artificial lighting that requires a decent amount of power which might be in short supply in a SHTF event. Mushrooms can be grown in your closet.
Herbs grow slowly. It can take weeks to grow a meal's worth of something like basil or chives. In that same time I can grow several pounds of mushrooms.
silasmoeckel@reddit
Yes a solid power power for the worst case a good greenhouse gets me working greens. My wife's sprouting setup works well for use it's enough to get some flavor and nutrition in on top of the carbs easily run off solar with modern LED grow lights.
The point is the nutritional value which mushrooms have next to none.
thomas533@reddit
Gram for Gram, microgreens and mushrooms are pretty similar for macro nutrients. And as far as micronutrients, greens will have higher levels of A, C, and K vitamins whereas mushrooms will have more B vitamins and can have D as well if expose to sunlight.
So it is wrong to say that mushrooms have next to no nutritional value. They are just different. An the fact that I can grow mushrooms on waste products in my basement in the dead of winter is very useful when I can't do the same for microgreens in my greenhouse.
Diversity is the spice of life as they say.
MaliciousPrime8@reddit
Wrong. Protein would be hard to come by if you dont want to wait nearly a year for your crop harvest. Oysters have a lot of protein that can be harvested very fast.
All with the ability to conceal them indoors, because they mostly don't require light, and can grow on materials that are totally inedible.
MyceliumJoe@reddit
65-130g of protein is nothing. Especially considering that every 2-3 months.. that's 2g a day. I, also, think you're vastly underestimating how hard it would be to get 10lbs of substrate per bucket and how much space that would take up.. that adds up very fast if you want to get a good amount of protein off them.
By all means, grow mushrooms.. but don't consider them a significant nutrient or protein source. Consider them a luxury item.
MaliciousPrime8@reddit
My friend, you can fill an entire room with 5 gallon buckets carrying 10lbs of wood each. That isn't hard to source, the trees are everywhere. I'd argue that grass clippings or even garden soil could work very well as a substrate.
You can massively produce protein in a very short time with oysters. About 4-6 harvests annually. They also contain about 100 calories a pound (wet) which isn't too far off from some staple vegetables like potatoes (300 calories a pound).
As for fuel concerns, something like a rocket mass heater can be very efficient on fuel. You're going to be boiling alot of things anyway if SHTF.
MyceliumJoe@reddit
How many 5 gallon buckets are you planning to use? Do you think that is a good trade? If you're banking on 6 harvests a year and 10 pounds per bucket(or 1000 calories per bucket), you'd need around 120 buckets to provide for one person completely if you want them to have 2000 calories a day.. or about 1200lbs of wood per harvest.. or 7200lbs per year.
And have you've actually tried to use a pressure canner with a rocket stove?
MaliciousPrime8@reddit
I corrected the calorie content (it's actually 30 calories per lb).
I'm not saying you should rely on this as your only source of food. All I'm saying is it's much more feasible (and even practical) than many people think.
Pressure cookers are not even required to grow mushrooms. I've had great success with just steam sterilization.
MyceliumJoe@reddit
That was my whole point. They aren't a valid staple in a diet. There's no problem growing some as a bit of a luxury. But, it's not feasible for it to be a staple or as a huge portion of your calories.
MaliciousPrime8@reddit
Agreed, it wouldn't be a staple, but it certainly wouldn't be a luxury considering how easy they are to grow.
Something like catfish or tilapia would be a luxury, as they require much more time/attention but can still be farmed on a small scale off grid.
thomas533@reddit
The value of mushrooms is that they can take waste products like cardboard, straw, and sawdust/woodchips and turn them into something edible. And the advantage of mushrooms over other things you can grow is that they don't need any light so if you are cooped up in your house you can grow them in a closet.
potato_reborn@reddit
They do have some great micronutrients though. Kinda like vitamin fluff.
caged_vermin@reddit
Certain varieties have some nutritional value in the form of proteins and minerals, shitake, oyster, but definitely not enough to survive on. That being said, I don't think it would be a bad idea to supplement your food stores with them though.
Exact_Comfortable634@reddit
I’ve thought about seeing if I could inoculate some of the random wood piles that the city leaves in certain places in the woods around town.
No_Locksmith_3651@reddit
If you keep a 50 lb bag of ag lime on hand, you can sterilize a lot of substrate.
Open-Attention-8286@reddit
I'm allergic to mushrooms, so growing them isn't something i focus on. But, I do know some gardeners who grow King Stropharia mushrooms in the same straw they use for mulch. They swear it improves their vegetable yields, in addition to providing mushrooms themselves.
They're probably right, as many fungi are symbiotic with the plants around them. But like I said, it's not something I've tried.
nunyabizz62@reddit
Its one of my main preps.
I have Lions Mane, Golden/Italian/Blue Oyster, 2 types of Shiitake a quart of each in the refrigerator.
I have over 300 pounds of Oak wood pellets, 100 pounds rye wheat berries, 1000 grow bags, an All American pressure cooker, and all other supplies, Martha tent, still air box etc to grow hundreds of pounds.
Lions Mane makes great steaks and faux crab cakes
ApresMoi_TheFlood@reddit
As someone who has grow several types of mushrooms, mushrooms are not easy to grow. They require a controlled climate, a large supply of substrate, and sterile technique to prevent contamination/not grow dangerous mold instead by accident with supplies that might be better used medically. Once all those things are in place or if you already grow then yeah give it a try, but don’t make your first grow be the first week of the apocalypse.
Unlikely-Ad3659@reddit
I have a family member who grew mushrooms commercially for 40 years. Mostly pick your own, but also for grocery stores.
His response when I asked "Mushrooms are easy to grow, making the soil and environment suitable for them to grow isn't."
Also my memory of his farm I visited as a child, it constantly stank of ammonia. Like stank stank.
ABC4A_@reddit
Takes a lot of fuel to sterilize things too, unless you want to do it via pH.
Uhbby@reddit
Solar pasteurisation? Say I took cardboard, grass clippings or other things oyster mushrooms can eat and compressed it like a paper briquette. As long as it wasn't too thick it might work. I have got a paper somewhere written by a guy in Thailand that used a Styrofoam box and a sheet of glass to pasturise medium. Failure rate might be higher but any failed blocks could just be composted or perhaps burnt as fuel.
I've got a grain grinder to powder dried lawn clippings, one day once I've rigged some kind of briquette maker I'm going to see how well it works. The grain grinder admitted is not great at doing its job though, but I continue to tinker.
Main issue other than maybe not being super sterile is senescence I think.
Humans can't eat grass or wood, might as well see if I can turn it into 1-3 useful substances: compost, fuel, mushrooms.
MyceliumJoe@reddit
I've grown mushrooms plenty.. I wouldn't rely on solar pasteurization. I'd use the canner i have to make a few jars a spawn, wait and see which ones develop without issue, and then try to make a liquid spawn, then inoculated the grain, box, whatever. Once you have some liquid spawn, that'd take alot of burden off your fuel consumption(you'd still need to make new jars occasionally though).
I, also, wouldn't grow oysters because I wouldn't have the space and it's not something you want to grow in huge quantities in your house(breathing in spores).
reishi mushrooms would be my top contender because you can just inoculate dead logs outside and pick them as they grow.
Either way, I'd treat them as a luxury item. I wouldn't worry about it until I had a plan for where to get the bulk of my calories.
Uhbby@reddit
How do you keep the liquid spawn sterile? I'm aiming for a low-tech, zero electricity set up.
And if you pick the oyster mushrooms at the optimal time then the spores are minimal. They need a bit of light and fresh air so I'll probably put them on my back deck as well, rather than in a room.
MyceliumJoe@reddit
Your sterilize it in a canning pot the same you would a normal spawn(but different time). You just want it to be water and 4%(for most) of a sugar. Besides that, you just make sure you use the injection port hygienically when you get the liquid in a syringe.
Occasionally you'll need to make a new jars, then inject some of the liquid spawn in it.
The biggest thing you'd need is a canning pot and a way to heat it consistently. I wouldn't use a campfire or anything, but you could use a propane burner.
It's not the best policy to use a spores syringe straight into LC, but I've done it to a few jars before as a test and got a usable one out of it. Just make sure you don't put all your hopes into one jar.
Uhbby@reddit
I've heard that both of those are harder to grow than oysters. I'm not sure of their nutrient requirements, but I'm pretty sure I've heard of people growing oysters off 100% cardboard pulp. Probably not very nutrient dense in those conditions, but still interesting.
MyceliumJoe@reddit
They're definitely slower growing and require a larger investment if you're growing them outside(which is what I'd . But, you won't have to worry about constantly finding cardboard.
I'd cut down a hardwood tree, put the log within shooting sight of my house, and inoculate it with alot of shitaki. It will produce mushrooms for a long time. Worst case, I get some mushrooms somewhat consistently. Best case, It becomes a bait for animals that I can hunt from my back porch.
Uhbby@reddit
I'll use whatever ligneous material I can find. Straw, sugar cane mulch, wood chips etc. Mix it with nutrient dense material, maybe compost.
What are your thoughts on winecap mushrooms? I've only heard about them recently.
MyceliumJoe@reddit
I don't know a ton about them but I like that you can use woodchips. I just worry about maintaining a constant supply of substrate.
Uhbby@reddit
If compressed briquettes work I could fully dry them and store a supply to rehydrate as new bricks come in to the system. There might well be a fair portion of the year where it's too hot here to grow oysters, in which case I could stockpile material during the warmer months. And if it all fails at least I have extra cooking fuel and compost.
cyanescens_burn@reddit
Very long time hobby mushroom person here (25 years of foraging and hobby cultivation). Indoor grows can require a lot of what you are talking about. Some species are more forgiving and the conditions can be controlled with a humidity tent, some are more complicated and might require more at certain times of year.
Outdoor grows can be even more forgiving. If you can get a bunch of hardwood logs inoculated with shiitake outside, a woodchip bed inoculated, or a mound of compost/manyfe/straw going you can often just add more pasteurized material to that bed and keep it going.
You are absolutely correct it is tricky in that getting them going from spore or tissue culture requires learning aseptic technique and getting or making some specialized equipment like a flow hood or still air box, among other things.
I’ve been tinkering/thinking, doing it as if I had limited electricity and supplies. If you have a solar generator or gas camping stove you can sterilize media, then it’s just a matter of sourcing material to grow on, and some species grow on a lot.
TL;DR, it does require more specialized knowledge and supplies than most people will have compared to plant gardening, but it can be learned with some effort, and pulled off with some effort.
hoardac@reddit
My pink and blue mushrooms once I passed the learning curve are pretty easy to grow.
kkinnison@reddit
better and easier ways to get nutrition. Bean sprouts for one. even microgreens
Vodkasody@reddit
Tell me youve never grown mushrooms without telling me
al_gorithm23@reddit
Despite what a lot of folks are saying, gourmet mushrooms are easy to grow, once you know how to do it. It’s the learning how, getting equipment and having a rigorous cleaning process. By easy, I mean the labor of growing mushrooms isn’t as intense as some other outdoor crops, and also the cycle time is quick, so you get a high yield relatively quickly vs other crops.
I have a full operation in my basement to grow 5-10lbs per week of oyster, lions mane and chestnut mushrooms. I grow them and give them to my friends, and trade them for other things that they grow.
My personal prepping using case for them is to have some produced food to supplement other more protein and carb rich foods. In my community network, I’m the mushroom guy, other people make bread and baked goods, others who have larger land plots grow vegetables, goats, chickens, etc…
It’s just one of many skills that I’ve accumulated over the years to add value to a community of people who are self supporting.
iwannaddr2afi@reddit
Do you have thoughts on how doable this is in a world where you can't order supplies, and maybe don't have electricity or the same stability of home heating and cooling, this would be? Basically asking if it's possible post collapse, which I know not everyone is prepping for! This is a real question, not a criticism at all :) tia
al_gorithm23@reddit
I mean, people have been growing mushrooms for thousands of years, so it’s definitely possible. Things that come to mind:
Pasteurizing using a wood fire, soaking in ponds and other clean bodies of water
Burlap bags or even old clothes for “bags” rather than plastic
Naturally gathering spores from the wild
Controlling humidity would be difficult, but not impossible. Bury soaked logs or other moisture retaining things in a cave or a basement
Contaminants would be the biggest concern, so you’d really have to select for more hearty spores through trial and error
iwannaddr2afi@reddit
Oh for sure, I get that we've probably always cultivated them to some degree. It does sound like a lot of fun to do indoors, but also not a skill I have yet. I'm growing outside for now (and trying to encourage wild ones), and even with the short growing season where I live, I might just stick to that. I'll keep being the bread person now and hope I meet a mushroom person lol!
thomas533@reddit
I have grown oyster mushrooms on cardboard, straw, and wood chips. I have even grown them on chipped up himalayan blackberry cane (something I have in abundance in the PNW). You can sterilize your substrate in a pot over a fire in your backyard. Then in a 5 gallon bucket, mix that with your spawn and you are good to go.
MaliciousPrime8@reddit
It's very easy and doable with primitive methods. At least for oysters.
KJHagen@reddit
Mushrooms are great for most prepping scenarios. The one exception is in relation to radioactivity. There are areas in Europe where mushrooms are still relatively toxic from the Chernobyl disaster.

barascr@reddit
if you like to eat them, you can grow them, but for survival food, they are not that great of an option, you would have to eat a lot of them to get a substantial meal.
That being said, I love mushrooms. Lol
PrisonerV@reddit
Just Google mushroom logs and also some mushrooms are great sources of vitamins and minerals. They're also low calorie so you can eat lots of them.
tinfoil_panties@reddit
I enjoy growing culinary mushrooms as a hobby but I wouldn't call them especially easy, and they also don't really provide any significant amount of calories or protein. I've also tried inoculating my yard with spores (which would be the "easy" way to cultivate them) but I haven't had much success with it.
alphatango308@reddit
Lots of people on here shiitake-ng on mushrooms (lol). But even if they're worthless nutrition wise, they can really help round out a salad or protein. Steak with mushrooms is delicious. And let's face it people sometimes it's the little victories in life that keep us going.
Greyeyedqueen7@reddit
Be sure to harvest before they produce spores if you’re growing them inside unless you want to find them growing inside your house.
Cute-Consequence-184@reddit
They make good ketchup but they can't keep you alive in an emergency.
MaliciousPrime8@reddit
To all the people who say you need special equipment: That isn't true. You can sterilize whatever you need with steam and make a still air box for successful innoculations. I've made even made agar plates with only potato starch as a media, and it worked beautifully. If you really need high proof alcohol, you can make and distill it relatively easily.
You can go all the way from spore to harvest with rudimentary methods.
MountainDonkey-40@reddit
“Medicinal mushrooms” absolutely
SeanusChristopherus@reddit
Would drying them make it a bit more of a viable way to supplement your diet? Don't mushrooms dehydrate/dry pretty well?
ogrezok@reddit
you need a special environment that requires light and humidity aka electricity, if you gonna grow it outside on your big property that different story
BigWooly1013@reddit
For what it's worth, mushrooms do not require light
Eleutherian8@reddit
They actually do need some light. While not traditionally photosynthetic, they do need at least a flash of the correct wavelength of light at a very specific moment to make the jump from pinhead to primordial fruit body. As well, most mushrooms need some light during the fruiting period to reach full size and attain their proper shape. It becomes clear that they like light when you see them stretching toward it.
ABC4A_@reddit
Wood chip pile with wine cap spawn mixed in, but it would need to be in the shade and watered well. But then the growth would be sporadic and not something you can really rely on.
tnemmoc_on@reddit
Food with calories would be better.
EmberOnTheSea@reddit
I have a colony of golden oysters I keep going in my backyard. They're pretty care free but the yield isn't huge. They won't make the difference in a survival situation but can definitely add some interest and flavor to those gallons of beans and rice.
Mundane-Jellyfish-36@reddit
It could be a part of a larger ecosystem. I am interested in hazelnuts which produce husks , shells and branch trimmings, which could be used as a growth medium.
AdditionalAd9794@reddit
Wine caps are super easy to grow, just innoculate a pile of wood chips, shiitake are probably medium difficulty, some other varieties are more difficult.
kite13light13@reddit
Easy to grow? Lol definitely not 100% true. I grow mushrooms and contaminants like mold is definitely an issue without good equipment
Ashamed-Knee9084@reddit
Mushrooms are not easy to grow. You have to have a VERY CONTROLLED environment and they are still very finicky. Different species require different substrates, lighting, air purification etc. They are very susceptible to "trick" which is a bacteria/mold that takes over. Once it's in your "lab area" the whole thing has to be sterilized and start over from scratch. Wouldn't recommend it as a "prep" but more of a hobby you don't mind blowing a Ton of money for high possibility of little to no yield.
Linds108@reddit
Growing shiitakes in logs by the creek is great!

My dad grew small batches of white button mushrooms in the basement. It wasn't very hard, kind of set and forget.
New_Neighborhood3987@reddit
Look into edible wood lover strain, Lions Mane, Black/Yellow Morel, Shiitake. Research an outdoor bed. This is a pretty good thread. https://www.shroomery.org/forums/showflat.php/Number/8167907/fpart/all
HRslammR@reddit
Let me be the first to say I know next to nothing about mushrooms. But what I do know, is unless you buy them from a store/restaurant there's a pretty good chance they will probably kill you if you eat them.
Again, I know there's some perfectly fine ones, but I would not want to risk that
nikdahl@reddit
Op is talking about growing mushrooms not foraging for mushrooms.
Even foraging is pretty low risk as long as you are careful. But still worth a word of warnings.
