I've used this guide over the last couple of years with great success, although I have recently learned that sterilized substrate can work as well. Anyone know if there is a thread that compares the spawn run duration for sterilized vs. pasteurized substrate? Are there even any beneficial microbes present in coir bricks?

There are no beneficial microbes in coir, sterilization works just as fine as pasteurization for coir. Anything else besides coir and verm needs actual pasteurization though.

Thanks, Inocuole! Should save some time to just sterilize in the future. 
Also planning to give your whole oats tek a whirl once all the WBS is gone!

im confused.... why cant you just sterilize the bags??? isnt that better to do?? because then there will be no contamination!

You can sterilize coir. You have to pasteurize if your substrate contains manure, straw, etc....
This is a pasteurization Tek look up a sterilization of substrate one if you want

After pasteurization, for how long can I use the coir? Is it ok to wait like 2 weeks in an airtight container and use it then? Will it change the humidity level of the coir?

Coir doesn't need pasteurization so you can leave it weeks.
Of you pasteurized manure or straw or anything but coir it needs to be used immediately
Coir doesn't have humidity air does Coir has water content. It wont change if it has no where to evaporate to.

I'm really contemplating using spring water for my next coir/verm prep. That one guys well water thread has me tripping. My water sucks dick. Shit all in it, slightly stinky smell, just wondering if maybe the bucket Tek isn't enough to treat the water.

Well you boil the water first for the bucket tek so the water is sterile

so one cannot pressure cook the mix? why is sterilizing bad in this situation?

I was wondering the same thing, perhaps because partial sterilization would leave the environment in the sub vacant like a vacuum attracting air particles from the air. Just a theory, I'm about to get to this part of my second grow and boy am I excited.

(Apologies if it's bad form to respond to such an old post, but this is still a heavily cited one and the question is on-topic, so hopefully it's cool.)

Reading a few of the well-known bucket tek posts, I've seen several people say that they've found that myc colonize coir faster when it's been cooked over pasteurization temperatures (presumably with higher contamination risk). If Frank's statement about good bacteria recolonizing overcooked coir is true, could you potentially get the benefits of both by mixing pasteurized and partially sterilized coir together in a relatively clean environment (like a sealed bucket or bag) for a few days before spawning in open air? At least in theory, you'd have more easily-digested coir than if you'd used purely pasteurized coir, but the good bacteria would have had the chance to recover and keep the overcooked coir from being as vulnerable as if it were used alone.
I'll admit that maybe this is trying too hard---I'm guessing the impacts on either contamination rate or colonization speed would be pretty small regardless, since both methods work pretty well on their own already. But even if it just reduces contam rates a couple percent vs bucket tek or speeds up colonization by a half day vs pasteurization, those benefits add up. And it's an easily testable idea, so perhaps someone's already tried it and reported back?
If not, could be worth trying. The test of contamination risk differences could be done without spawn using just a bunch of jars or other small containers with a handful of coir each, with the test being to see how long each one stays trich-free. A couple bricks would give a good sample size, so cost is trivial. Then if that is promising, you could test colonization speed across some shoeboxes or other small containers using the same batch of spawn.

Coir doesn't have beneficial microbes in it anyway. Pasteurizing coir is absolutely pointless you might as well pour boiling water on it or sterilize it.
Also the word beneficial might be misleading. Those microbes might just be preventing molds from growing and ruining a grow but the microbes themselves might also lower yield. As some people have sterilized manure and spawned to it aseptically those grows do seem to give as good if not better yields. But to spawn to manure aseptically isn't necessarily worth the hassle.

Thanks. Did some more research after and realized what a delicate topic this is - some of the flame wars between TCs are pretty epic. Think I'll just pretend this subject never came up...
