Is it possible to do this using a much smaller PC? I don't have one nearly that big and can't afford it right now. All I have is a 4 qt one.

Thanks for the guide Frank. I have followed your guide with some success so thank you for posting this! I was wondering if you have ever tried to pasteurize your coir/hpoo mix in vacuum sealed bags. The reason I'm asking is because I have a sous vide (hot water bath) and I can do 4-5 bags of about 10 quarts of substrate at once if I use the vacuum seal bags instead of the filter patch bags. I just have read mixed things on if the lack of oxygen is a factor for contams. Thanks for your help.

Sorry, I know this is an old thread, but it’s a great one. Saved my ass when I didn’t make enough bulk to add a sudo-casing to my shoeboxes. Thanks for the great detail on the write up man.
Nice easy 2 hour sub/casing. I wish I had a bigger PC so I could do large bulk bags this way. My pasteurizing chamber works okay but it’s still a pita having to pull out the bags and beat them up to distribute the heat evenly.
I do it anyways with this tek just to make sure I’m getting up to temp quicker and more even, but it’s al lot less likely to steam burn the fuck out of my arm than the chamber.

"If the temp goes over 170F for more than ten or fifteen minutes, you will start to partially sterilize your substrate. It'd be best to toss it and try again. Since we spawn to bulk in open air, a partially sterilized substrate is often as shitty as an unpasteurized substrate."
Why is it bad to sterilize or partially sterilize the sub? I understand that we're just trying to pasteurize it, how can over cooking it be bad? Like if I were to straight boil coir for an hour..

Partial sterilisation kills beneficial microbes, and creates living space for molds and bad bacteria to thrive.

Is leaving them to cool for 18 hours too long?

Does the jars need to be submerged under water for this to properly work? I have the presto 23q pc so I can fit 10 in I believe but 3 would be out of the water on the top on there side. Also if I can do this with 10 which jar would be the best to take temps from the one in water or laying on top?

I have built a steam sterilizer. I can maintain a temp range of 150 to 160 in the drum. I am using 1 gallon glass jars to pasturize coco. I maintain the temp range of 150 - 160 in the 44 gallon drum until the internal temp of the jars hit 155 then shut the system down. This means internal temp stays in the 140 to 160 range for 2hrs. I wait until temps cool to 80 before I introduce grain.
I feel I am being super accurate in trying to achieve perfect pasturization but I am getting 90% contam rate. I'm being super sterile with my handling and prep of the substrate and mixing the grain.
I've tried experimenting with longer times and higher temps but unsure why I am getting so much green. Can anyone offer any assistance? I've just about pulled all my hair out!

my guess is your spawn has hidden contams specially because its not necessary to even pasteurize coco coir

I had given that idea serious thought but my contam rate in my grain bags is very low, less than 10% so I put a line through that as a the cause.
I have read that coco does not need to be pasturised, I find this info confusing and don't understand why there are so many open threads and teks on pasturising coco.. I mean, if all the pasturising coco teks are bunk and the whole idea of pasturising coco is obsolete, shouldn't all the threads be locked? If there is a diffinitive source of info or a link that someone can share in regards to this, please do.
Further reading has narrowed me down to air being the source of contam. I'm going to try pressure cooking and sterilising my polly fill. Perhaps this is my source.
EDIT
I found this thread https://www.shroomery.org/forums/showflat.php/Number/24974307 and it has opened up another possibility to my trich issues.
My process may in fact be part sterilising the substrate and that's why I'm getting contams.
I'm going to do a side by side side test
I have 12 healthy grain bags. I will do three straight to coco hydrayed with water at room temp. Three to coco hydrated with hot water from the tap approx 115°, after temps cool to 80. Three to coco hydrated with boiled water after cooled to 80. Three hydrated with 165° water, put in my drum steriliser and maintained at 165 for 60 mins then cooled to 80.

With coco and verm clean spawn is all that matters. Case is closed

I hear the outside of the jar may get sterilized with this tek let me know if I’ve had problems.

I have the water halfway up mine , do 7 to stay consistent , the top 3 won t heat as fast but add another 20 minutes it can be done just check your core temps of both top and bottom jars

Wanted to bump this with some information that might be helpful to others using the tek.
I have been using this tek more often recently and most of the time I’m drunk or otherwise distracted when mixing my sub. Sometimes I’ll have jars start temp at 70, other times they’ll be in the low 60s. Often because I accidentally use cold water to mix instead of hot.
I used to follow Frank’s advice to a T about jars starting at 80 because I didn’t like the ambiguity in trying to figure out how I should adjust my temps. What I’ve realized is that in my process (lid on presto with arrows aligned, cold water halfway up the jars, stove on medium) is that if I just divide my starting temp by 0.8, I know what temp I need to shut the oven off.
Examples: I mixed casing material with warm water. My jars started at 70. 70/0.8=88 degrees. Killed my stove at 88. Stayed in proper temp range the whole time.
I mixed casing material with cold water from the tap. My jars started at 62. 62/0.8=78 degrees. Killed my stove at 78. Stayed in proper temp range the whole time.
Nothing revolutionary here, just a rule of thumb that I’ve found helpful when using water temps that are different than in the original tek.

Hey Frank, Question about doing an alternative filter bag pasteurization:
how about doing something between bucket (pillowcase) tek and the filter bag tek where you mix up your substrate, bring it to field capacity, then throw it in a pillowcase and elevate the mixture above the water in the PC so there is no leeching of nutrients. Probe the center of the mixture, bring up to the temp, and pasteurize that way?
Sorry if this has been discussed before, I couldn't quite find anything about the pillowcase actually being elevated out of the water.
-------------------- We all don't know until we do know.

Thank you Frank!

Ive just been thinking about the bag pasteurisation and the time.
If you wanted to do it fast, You could -heat water up to 170 like bucket tek -hydrate the coir and using gloves and a spade fill a bag or bags. Temp will be anywhere from 130-150 at this point. -Put them in the kettle -add water to kettle as described but at a higher temp(no higher than 170) - Keep temps in the high 160s with heat -Take core temp -set timer when it reaches 140.
From start to finish no longer than 2 hours and you wouldn't get the inconsistent temps of bucket tek.
