googled “oven tek pasteurization” & this was like the first result. i’m sure you could adapt it into whatever you can make work.

Mad Season said: Except you need microbes. Manure is FULL of it. It's actually in quite a few documents that you want to hydrate it and let it sit for a bit before pasteurization so the beneficial microbe count can be higher prior to pasteurization. Pasteurization kills about 75% of the microbes, as well as killing almost all of the molds.
There are some thermophilic microbes as well that will thrive at higher temps and take over the manure if you slowly cool it over night. By doing so it'll get colonized by beneficial microbes that won't let invaders like trich in.
Also lastly pasteurization imo shouldn't go past 155. The closer to 140 you are in the center of the substrate you're pasteurizing, the better. I do 140-150 for 1 hour. Almost all molds die at 130 for 30 minutes, so really anything more kills beneficial microbes.
Tell that dude that i still at this moment have hydrated, properly pasteurized manure in open air, in my basement that has ZERO visible molds. BTW I just found this lost in my basement a few days ago:

and the manure still isn't contaminated. This leads me to believe that as long as your manure is properly pasteurized any contaminations like trich are always from bad spawn. I'd bet a major difference between now and back then is the cleanliness of your spawn as well.
the thread i linked has even more info, but it’s pretty much just that good microbes help fight the bad ones. if you get rid of the good ones, contamination has much more of a foothold to infect your tubs

old thread but you don’t really need to pasteurize casings, even if it’s peat. you case at 100% colonization of the tub, or you can do a pseudocase right at spawn. i don’t really know what other questions about casing you would have.

coir doesn’t need to be heated at all. you can use cold tap water to hydrate coir without any contamination. manure & straw do need to be pasteurized properly for the reasons above

You probably don't wanna know this but I'll assume here (you were asked twice but didn't answer) that you still need to learn agar.
My guess is still the obvious: It's your spawn. No matter how you heat your sub, bad spawn will cause contam.
I pour boiling water on my coir in a cooler and that's it and have never had one contam bc of it. I have had plenty shit happen to me bc of spawn that I was 'certain' was good. In hindsight, it wasn't.
This is likely also what's causing your problems rn

If you want to pasteurize a ton at once I think someone had a trough coir tek going on use the search function to find it yo. Basically threw all the mix in a large metal container from there you could add a heating element of sorts. King Louis Pasteur says to get it up to 140-160 for an hour don't over complicate it.
Cook below 140 it's not pasteured. Cook over 160 you're killing off everything that can save a grow a flush down the road.

Casing a tub is not going to magically make a contaminated sub start pinning.
You have a pressure cooker, it’s shaped sort of like a bucket.. I’m positive you could figure out a way to make things work with info from here and supplies you already have.
The most important part of mush cult is producing clean spawn and you’ve posted pictures of non clean spawn and said you’ve been having issues, that’s probably a huge part of your issues and why people keep mentioning it.
If you’re using just coir/verm then you don’t need to properly pasteurize. You can use hot water, boiling water (to cook the coir a bit which helps colonization) or room temp water. It doesn’t matter. These little Tupperware I did the coir with just cool tap water If your coir sub tams out before first flush you know it’s your spawn being dirty.
Hpoo and stuff needs proper pasteurization to consistently work or total sterilization jars/bags in the pc maybe.
