well if you want an 80% chance of it stalling and getting contams, then dont pasterurize. right?

Its so easy to pasteurize why not do it?
I make my coir sub in the PC.
Mix it all up and put the lid on and get over 200f
Dump it into a bucket with a lid and let it sit all night.
When I wake up I use it.
Its to easy not to.

I dono I've read a lot of noobs who don't pasteurize and I've also left coir sealed and hydrated for a long time with no contams. I always pasteurize though, usually it's mixed with the rest of the substrate and pillowcased. Maybe I wasted my time doing this but I'm on to woodloving edibles now so I doubt I'll try not pasteurizing either anyway.

Horticultural coirs often have large amounts of trichoderma in them because it is beneficial to the root systems of some plants.

The coir that I have stored in a sealed container is of a gardening variety. However that said I hydrated it most often with hot water so... 
On the other hand the one type of gardening coir that I got is not specifically absolutely identical to all varieties and in fact as could be people's experiences with it. It may all boil down to what kind of coir you have and how/where you prep it use it or store it.
You wana test your coir out? Take some hydrated coir and leave it in a small Rubbermaid container for a month to four months and check back every so often. if it's completely not infected within a month you should (hypothetically) be able to use it just prepared and not pasteurized (since no colonization should take this long). Longer term will tell you if you can store it after hydration.
Personally I think this approach is kinda messed up because there could be other unknowns and it risks productivity where I suspect a change of procedures could suffice to make up for whatever motivates you to peruse this shortcut.

It amazes me, coir sitting damp, in a CLOSED bucket, for weeks and months on end, and no contamination . . . It gets to 100+ degrees in my garage these days.
I stare at the bucket and vow to never blame coir again for my contamination woes . . .

"I stare at the bucket and vow to never blame coir again for my contamination woes . . ."
I figured as much. Just curious what people had to say about this. Obviously its fine to play it safe. But from what I have read up on, contams come from other sources. Witch can range vastly!

most contamination problems are the result of contaminated spawn or contaminated inoculant. It takes a quick fast growing contaminant to hack it in the substrate against healthy mycelium spawn. Coffee grounds are the only thing that springs to my mind that as a material is so prone to contaminate that it becomes a risk as a substrate additive. Mix your coir with some good quality pasteurized nitrogen rich poo and you shouldn't have any problems from your substrate. That is obviously barring some instances like thedeafone mentioned or if some way you are prepping/storing it is contaminating it.
Also since I'm on the topic, keep in mind that even stored in the fridge LCs have a shorter shelf life than people generally think, I find that 3-4 months and you'll want to make another one (it's not 100% after that point). I suspect one of the biggest contaminant problems for people in this sort of amateur setup is old fridge stored LCs. I know it looks sealed but it isn't fully sealed ever, eventually something will get in or germinate or whatever and your LCs will turn.

Yeah I mean its so easy (at least for me) to create LC's I dont find a need to store for such a long time anyways. But everyone has diff plans for things.

I think it's generally a lack of planning that leads to use of old LCs.

I dunno..
I think pasteurization is good for the other nutrients being mixed into the sub, like coffee; along with being a more sterile way to hydrate the coir.

well I use a coir based bulk, I usually don't pasteurize unless I use Hpoo. I just put a brick in a bucket & add a gallon of boiling water. then cover with a lid until it's cool enough to use. I know this works because I have a bucket that's 3 months old I opened it yesterday & there no mold or anything.
