Well I am curious now. Gonna try an experiment I have been meaning to do for a while. Gonna get to the bottom of this one.

Awesome, I'm really just curious about it because I have done tons of things to prep coir that just wouldn't work with other substrates and have never ran into issue's I could blame on the sub, so I am open to whatever you find out is behind this whether the coir is super clean after being bricked thus easily sterilized or just really resistant towards contamination which the second is what I have always thought. What are you thinking about doing for an experiment?

Okay now you are not understanding why coir works. It's fine sterilized simply because molds can't germinate on it and it has no real food supply for bacteria. That is what makes it safe no matter what you do. The fact that populations are probably low is just a bonus.

Exactly what kind of populations can be found in a brick of coir. Should be easy enough to see. Of course I can't do a specific ID but it would be interesting to see what popped up be it mold bacteria or yeast or even higher fungi.

I wish I had a nice microscope, what I may be misunderstanding then is why with with this specific substrate when sterile is mold less likely to germinate on it as apposed to spawning to sterile sawdust which needs to be done in a sterile environment? That seems to be the mechanism that makes coir so unfuckupable, non treated or sterilized, in fact I am still betting against that coir is sterile after a bucket treatment, no way. Now from an organic gardening perspective coir is used because of it's unique properties of breeding beneficial bacteria and fungi, in fact I think you guys know Trichoderma is even added to coir.

I have no idea why shit doesn't germinate readily on coir. All I know is that it doesn't.

I know right? Pasty is fucking moses where newbies are concerned. It's like RR(which would be god in their eyes) called pasty from the sky and pasty went up the mountain and returned with stone tablets explaining everything mycological. HAIL MOSES
Fuk dat, joo ain't pasty nigga, youse a liar.

Rooster Cogburn said: Not just manure, basically every other substrate used in mushroom cultivation, needs to be properly pasteurized or sterilized or it will inevitably fail. And as far as these coir facilities in Sri Lanka and what not, I am not sure that these bricks are being heated up to the point you guys think. How? What is the heating process besides the pressure, it seems like third world facilities like that would be using as little energy as possible and the amount of energy heating that much waste product seems completely inefficient for a business in a third world country, especially one producing gardening supplies.
Don't you know that compaction and high temps go hand in hand? They probably don't even heat the coir, the act of compacting a brick of coir to that density will create it's own heat. It's the same reason why foot operated bicycle air pumps get warm after using them or why aerosol cans get cold after releasing their pressure.

To tell you the truth I have only seen pictures of the devices they use, I have never seen or read any papers or documents on how much heat is produced while they are pressed, and seeing they are usually pressed into 650g blocks or 5kg I cant see them hitting sterilization temps. But I don't really know, it's just my opinion, I am totally open to being wrong. Anyways I started a series of experiments to check this out, here is the thread https://www.shroomery.org/forums/showflat.php/Number/23542736

Well, seeing as how I've seen these industrial machines pound the living fuck out of pieces of metal and eventually make them glow red hot, I wouldn't bet any money that sterilization temps aren't achieved when they compress a block of coir.
It's easy to get an slight idea of the forces at work here. If we are able to get a leg operated air pump warm simply by pushing it with our feet, it's not that hard to simply imagine just how hot coir can get with tonnes of pressure compacting it. I mean, even if you just grabbed a piece of soft metal, say aluminium, and twisted it back and forth, it will end up too hot to handle with your bare hands. And that's just from KGs of pressure, not tonnes.

You guys have a great point. I found a video of a coir pith in use here, I can't tell if the coir is coming out hot or not?
