Reddit reviews The Mushroom Cultivator: A Practical Guide to Growing Mushrooms at Home

Actually, in most cases it isn't, but it is pasteurized. Sterilization would make the medium insanely contamination-ridden, due to the lack of competing microbes. Once mold starts growing, you've gotta toss the medium completely. While this is probably a nice hippy-dippy way to sell mushrooms, there's no way it's going to maintain healthy flushes for long with a "tame" culture like agaricus bisporus. It just can't compete with molds like trichoderma, which is possibly the most common mold on earth. That's not counting the possibly hundreds of people touching the growth medium, throwing their trash in it, discarding unwanted mushrooms into the pile, and the like.

I've read a lot about it (I was once an aspiring mushroom farmer) and I believe it has something to do with pressure+heat killing fungal spores, but leaving beneficial bacterial endospores intact. Essentially, the bacteria and other microbes take up real estate until the fungus shows up, and then it moves into their turf and consumes them as well.

The interesting thing is that in commerical mushroom grows, pasteurization temps are reached naturally due to the size of manure piles. The mass of the piles coupled with the immense activity of microbes within them raises the internal temperature to anywhere between 140f-170f.

Edit
Here's some more places to find information about mushrooms, since I'm hardly an expert. I'm just a guy who reads a lot, essentially.

Books:

• Growing Gourmet and Medicinal Mushrooms, Paul Stamets
  
• The Mushroom Cultivator, Paul Stamets
  
  Those are the standard grow manuals, but if anyone has a suggestion for a more comprehensive or up-to-date manual, it'd be welcome. Mycelium Running is a great book if you're just looking for a fun read about mushrooms.
  
  Websites:
  
  
• /r/mycology - The subreddit devoted to mushroom growing and identification. Probably more relevant info here if you're interested in growing mostly edibles.
  
  
• Fungi Perfecti is good for equipment (I bought all my HEPA filters there, at the time they were the cheapest around). I think they have a YouTube channel too, and that's got some interesting stuff on it.
  
  
• Shroomery.org is a moderately famous mushroom growing forum, with a bit of a bent more toward psychedelics. However, I found tons of great people and information in the edible mushroom forum, and I received a few commerical grade cultures from a very generous member. There can be a bit of a circlejerk surrounding some "celebrities" that post there, but take what they say with a grain of salt, and always fact check against your grow manual. If you see something that looks stupid, it probably is, unless it works. Edit: I don't think Reddit likes linking to the Shroomery, removed the formatting.
  
  Videos:
  
  
• TED Talks: Paul Stamets - Six Ways Mushrooms Can Save The World - This is basically his "standard" speech he gives when he does talks. There have probably been additions and improvements to it, but the message hasn't really changed. This is "Mycelium Running" in about 5 minutes. Watch this to decide whether you want to read that book.
  
  
• Let's Grow Mushrooms! by Roger Rabbit - One of the aforementioned Shroomery celebrities. His videos are helpful, but make sure to fact check why you're doing stuff, because he tends to leave a lot of that out. This is very nuts and bolts demonstrations of how to prepare substrate, how to provide humidity at a low cost, and several different methods of growing for different species of mushrooms.
  

Buy a regional guide. Here are a few if you are in the US. It's important to know the terminology that goes along with mushroom hunting.

Also Use the links in the sidebar here, they will tell you the active mushrooms in your area. Once you do this do individual research on each one.

Mycology

The fifth kingdom beginner book, I would recommend this. It goes over fungal taxonomy Oomycota, Zygomycota and Eumycota. It also has ecology and fungi as food.

The kingdom fungi coffee table book it has general taxonomy of the kingdom but also very nice pictures.

Introduction to fungi Depends on your definition of beginner, this is bio and orgo heavy. Remember the fungi you see pop out of the ground (ascos and basidios) are only a tiny fraction of the kingdom.

Try looking for The Mushroom Cultivator by Paul Stamets.

Read Paul Stamets book Growing Gourmet and Medicinal Mushrooms, and also The Mushroom Cultivator which details a lot of info on spore storage and culture practises.

Its so easy to get one contam spore into whatever you're doing - ordinary air has so many contam spores in just 1cm^3, its almost impossible to work 100% sterile. But not to worry: the best we can do as cultivators is hold off the inevitable. A good cultivator will do what he or she can to work clean but all the time understands that all grows will ultimately end in contamination - thats just natures way.

The contaminations themselves often sporulate on the surface of cube spores which after finding residence on nutrient media will then 'piggy-back' using the spores which touch each other. The contaminations can often be 50 times smaller, and so can easily rest like a pest on the spores surface. An electron microscopy picture can really show you well what I'm trying to say here. They also reproduce far faster than their larger basidiospore cousins in the cubensis family, so can out compete them for the available resources that you have so kindly provided for them.

Its not that having a lot of spores in a syringe is a bad thing, its just that throughout my experience with cubes I've found that 'less is more' - the more spread out the spores are from each other, the more you can isolate the good strains and culture out the contams. :)

My complaint about these books is that they are geared for exactly what you're talking about and not necessarily low-tech home cultivation. They cover just about everything you would need.

Paul Stamets cover everything in this book. Avoiding syringes will require you to use agar methods and this guy does a great job of explaining it all.

Mushroom god paul stamets has made leather out of mushrooms. His hat that he wears is mushroom leather and is over 3 yrs old.

The indoor mushroom growing guide. Great book.

I'm also looking at other non-mushroom eating ideas like using the mycilium as packing/building materiel.

If your serious about it, https://www.amazon.com/Mushroom-Cultivator-Practical-Growing-Mushrooms/dp/0961079800 , this is your fucking bible.

This is a really good book

This book and this book are the bibles of growing mushrooms. They cover growing both psychoactive and non-psychoactive including Coprinus.

Check out this book by Paul Stamets His work is highly regarded in the mushroom community. You can learn everything you need to know from his books.

No worries man! I’m about to start my fourth grow when my spores come in so I totally get where you’re coming from. It’s such a fun process and I’m constantly learning more and more. You should check out this book called The Mushroom Cultivator. It’s such an invaluable reference tool that I’m constantly flipping through when I’ve got questions.

Edit: It’s a little dated, and PF-Tek was published about 10 years later, but everything in the book is still valuable and informative.

The Mushroom Cultivator is a fantastic book. Can't do without it. Sterile culture, expansion, fruiting, everything. Must have. Same goes for all of Paul Stamets' books, really.

Cloning is actually pretty easy if you have the right environment and a few bits of kit. Good luck! I look forward to photos of your grow.
