Just a side note. I started growing mushrooms a couple of years ago.

Very interesting and fulfilling hobby, they are incredibly interesting critters. Takes a little bit of dedication to get started but once you start seeing them fruit and making your own substrate it's quite inexpensive and a lot of fun. I have a feeling lots of folks in this community would really like it.

Basic starter package is a 'monotub', selection of spores, grain for spawning, substrate for fruiting and miscellaneous bits and bobs for handling, hydrating, maintaining temps and cultivating. North Spore and Midwest Grow Kits are both reputable and reliable suppliers.

Tons of resources on YouTube as you might expect. One of my favorites is Southwest Mushrooms - https://www.youtube.com/@SouthwestMushrooms

How much trouble is it? I found with gardening that it was fun for a while, but not fun enough for me to sustain itself as a hobby for it's own sake. And the time investment was not worth the crop.

I'd love to grow mushrooms if, once you get past initial learning, it's very low-effort.

A thing I've been wondering, I might be completely lost in thinking about this, but do you know: If you grow mushrooms at home is there a risk that it spreads as kind of fungi to the building, furniture etc.?
reply
jcims 4 hours ago
I agree with the replies so far in that there isn't a major risk of the mushrooms spreading.

That said, it's not completely risk free and I think it's important for folks who decide to get into the hobby at least take a moment to think about it. If you have someone in the household that has respiratory issues, I think it would be worthwhile ensuring that you have good containment to prevent spores from circulating the home (or do it elsewhere). This is particularly true if you decide to scale up (which is natural once you have some success, it truly is fun).

Also the growing environment is subject to infection from whatever environmental molds/fungus/etc are around, so reasonable precautions should be taken when handling/disposing. Once you get your procedures down this is less of an issue but still something to keep in mind.

Personally I didn't do anything but very basic precautions and never had an issue.

Mushrooms are everywhere. There used to be a subreddit of "weird mushrooms" like growing out of people's couches or in the bathroom, etc. In all cases, this is a sign of rot due to water intrusion.

You can grow mushrooms at home, it is fun. The only risk is that the mushrooms with high spore production are not great to have in a closed residence, especially oyster mushrooms which produce very high spore loads. There are vendors who produce cultures of sporeless oyster which can be used to grow oyster mushrooms indoors.

Outdoors, at least in most temperate areas, you are limited to things like shitake on logs or winecaps. The latter are incredibly easy to grow, and very good taste wise, but they are temperamental and basically grow on their own schedule, infrequently.

Normally the risk of airborne spores taking over your growing material is much more likely than your (most of the time very selected and in no way adapted to the "normal" surroundings you try to grow them in) taking over your home. Keep in mind that almost all fungi like similar conditions and there are already loads of spores of fungi that are more adapted to your living conditions in the air.
reply
ksymph 5 hours ago
Nope. Edible mushrooms generally need similar conditions as mold/mildew/rot to grow, i.e. moisture, low light, and the right material -- though they tend to be pickier, and are less suited to human-adjacent conditions. So if you find mushrooms growing where they shouldn't, there's a much deeper moisture and mold issue.

I started a few months ago and it’s a great hobby. It’s like low maintenance gardening that you can do all indoors. It’s very satisfying to watch something grow. I think my only reoccurring cost is the coco coir I use as a substrate and the wheat berries, which are both very cheap.

Is there any risk of wild, potentially dangerous, mushrooms colonizing your garden?
reply
foobiekr 7 hours ago
There is always a risk of things like this. For example, to make my winecap bed, I had to get a bunch of woodchips. There is no way woodchips that one will buy in bulk are not contaminated with the spores of other wood-eating fungus.

What you learn is how to positively identify the mushrooms you intend to produce/eat. It doesn't take long. I've only had alien mushrooms show up once.

On the other hand, the morels that seemed to come with a load of wood chips were great for the year or two we had them.

I tried growing a little wine cap bed once, and it hadn't gone well. Perhaps it was the chickens pecking at it, can't say. I do still get wine caps on occasion, but they have migrated to more far-flung parts of the yard.

Do people ever try to irradiate or fumigate or however they’d treat the woodchips?

Adding poisons (fumigation) is definitely not a good idea. In mushroom plants the compost/humus used to grow mushrooms is often steam boiled to sterilize it, to keep the yields high and the production safe from any dangerous contamination. It is seeded with the spores of the desired species afterwards.

I imagine it would require the bad spores to be carried with the good ones. Typically you get a slurry solution that you carry in distilled water, injecting your substrates. That would need to have the bad stuff in it as well.

Wild spores and such yeah. When you purchase spores for the intent of growing them, you generally get a kit to mix them into a syringe or they already arrive in the syringe ready to be used. I tried growing some culinary strains and they generally come in the mail like that.

Certain species do better in different substrates, but for the ones I've grown coco coir (also suggested by holly01) works great. There are some additional bits you can add to improve results but it starts there. You can hydrate it with hot water in a 5 gallon bucket. There's lots of tutorials on YouTube.

Depends on the species. For something easy to grow like oyster mushrooms, straw. Do decontaminate the straw. Cooking water or hydraulic lime water should work for that.

Coco coir is very cheap and is what I use. If you want more of a project, you can make the inoculation jars and sterilize the grain yourself. That way you’ll be taking a spore/liquid culture syringe from a tiny blob of mycelium to a whole network of fruiting bodies. Doing that will also be much cheaper in the long run if you stick with the hobby

There are a few companies in this space, notably Ecovative, who have been trying to make mycelium-based packaging for almost two decades.

The problem is that it takes around 7 days for each piece of packaging to "grow", and the finished part is heavy and not compressible so it adds significant cost in manufacturing, storage and transit. And these costs don't get any better with scale.

For those reasons, mycelium packaging hasn't seen much adoption beyond being used as a marketing story for high-priced small goods. Environmentally forward companies have tended towards paper-based solutions like molded fiber.

reply
Tepix 9 hours ago
Heavy?

Two packages made from mycelium can behave very differently because “mycelium composite” is a category, not a single recipe. Particle size, fibre content, and the ratio of substrate to mycelium all change density. Higher density generally brings higher compressive strength and better edge definition, but it also increases weight and can reduce the springy cushioning that protective packaging needs.

Sounds like this might be your area of expertise. For the rest of us, take a shoebox. How much ballpark extra weight we talkin’ to have a livable planet? (Maybe the mushrooms would be ~2x as heavy as standard shoeboxes for example, to meet existing spec.)

Or how about for the glasses box they show on the site in OP, or a plastic sleeve like Americans sell Oreo cookies in. Anybody have any guesses?

reply

Hopefully not used as packaging for Oreos, because unless the fungus has been highly adapted to the substrate, the mycelium will try to grow into the food. Oyster mycelium won't be toxic, but I don't want my Oreos to taste like mushrooms.

I've done some experiments with mycelium as a construction material, but I'm hardly an expert. Mycelium weighs anywhere between 50 and 950kg/m3. Usually you won't have mycelium as thin as cardboard, because you want use mycelium as a 3d buffer, replacing styrofoam. EPS (styrofoam) has densities of 15-30kg/m3. So while it's more sustainable it's also heavier.

Biodegradable foam packaging, as well has food containers, disposable cutlery, etc, has also been made from corn starch for decades.

I’m curious what the advantage of mycelium packaging is over these existing materials. Presumably, it’s not cheaper to produce? Is it mainly that the mycelium degrades faster and can be recycled more easily in home composting, etc? Or is this about creating “hard” plastic-like packaging that resists crushing, water, etc?

reply
nine_k 3 hours ago
Theoretically fungi can live off sawdust, don't need plenty of light or watering, etc, so they should be less expensive than corn.

OTOH corn is highly optimized over centuries of breeding, harvesting, and processing. Fungi, not nearly so, so by now they may be more expensive.

My sister worked as an intern on mycelium as fertilizer. Basically, using cover crops create a small mycelium layer that helps plant grow and reduce fertilizer use (by fixing nitrogen probably). Her job was to find molecules that would make the mycelium, and only the mycelium, grow quicker.

That's a very interesting field to study, and it seems promising.

In the old days, wood shaving and even popcorn were the packing material of choice.

The reason styrofoam is used is because it's cheaper (main) and it doesn't decompose when wet.

Molasses was cheap because it was the packing material for plate glass - which was only made in England. Place your plate glass in a barrel, fill it with molasses and you can ship it to North America. Just wash off the glass and you're good to go.

Well there are multiple types of molded paper inserts. Egg carton-type material on the cheap end, and that super smooth stuff that Apple uses on the other (these generally have additives in them - they aren't just paper). In terms of "premium"ness this sits in the middle.

Apple was using a cellulose foam mixed with a starch based biodegradable binder, one that was very slightly different from Paperfoam to save them money on licensing fees.

Now they just use 99% compressed cellulose with a few antistatic additives.

A trademark sets your brand apart from competitors. If your competitors are other brands of mushrooms, then "Mushroom" is too broad. But if you're trying to distinguish yourself from other brands of packaging, it might work.

If it got litigated and I were the judge, I'd be concerned they were trying to abuse trademark to get patent-like protection. In the narrow packaging market, another mushroom packaging competitor would have trouble talking about its product without mentioning the word "mushroom" and drawing the ire of Mushroom™ lawyers.

Not certainly. A LARGE number of fungi grow just fine without manure. I think this is a common misconception since agaricus bisporus (portobello, bella, white, cremini, button) need it to grow well, and it is the most commonly human-grown fungus by a long shot.

It seems rigid though, more akin to cardboard than soft styrofoam. I don't see anything about how dampening it is, but from the pictures I also assumed it was more like cardboard than styrofoam. Maybe the color is deceiving me though.

This seems like a nice stepping stone towards something cool, but having the forming happen at a dedicated facility seems to miss the point. The promise of this technology is that instead of:

- make packaging

-> ship to where product is packed

-> ship to consumer

-> ship to recycler

you can:

- grow packaging where product is packed

-> ship to consumer

- consumer composts it in their garden

That is, the packaging should just make one trip instead of three. Hopefully they eventually figure out how to make kits so that shippers can just grow the packaging around the actual product. The hard part will be ensuring that the biomass used as feedstock (likely a waste product from some process nearby to where the product is packed) is actually something that people want in their garden. Doable, but maybe not the kind of thing markets can be trusted to do on their own.
