The water cools the substrate off to 212.
It's not good.
The jars are supposed to be shaken a few times to distribute moisture. Wait.

I use usually turn the stove down so the PC operates at 14 psi, and almost no steam escapes, thus it runs for hours on very little water. RR

Perhaps the instructions for the pressure cooker had too much water on the bottom.
It's irrelevant how much water is in the PC because the jars are supposed to be elevated completely out of the water on a rack. I don't allow any water to touch the bottom of 1/2 pint jars at all. With quarts, I let them sit about 1/2" deep in the water. RR

RogerRabbit said: I don't allow the water to touch ANY part of the jar. Two rows of jar rings will get the bottom of the jar out of the water. If you don't have that, use a row of empty jars on the trivet, so the jars with substrate are elevated out of the water. 1/2 pint jars are not tall enough to avoid the splashing as the water boils if they're down in it.

Not sure where people are reading bogus info that says the water cannot touch the jars, but there is no logical reason to think this.
In RR's movie "Let's Grow Mushrooms" they mention that they don't want the brf jars touching the bottom of the pressure cooker because the heat could potentially cook or dry out the substrate, or even crack the jars. I presumed that boiling water could potentially also good the substrate. Clearly it doesn't crack the glass during making LCs

Steam in a PC gets hotter than boiling water....your logic needs more logic....

Are you quoting stuff on making cakes? Put the links to the quotes.
'It cools the substrate' what? Op is talking grain jars.

Read the last post. I'm not gonna link all of the quotes, you can look them up if you wanted. I'm not done.
And to fair I've seen a few posts saying half an inch up grain quart jars isn't a big deal.
Steam is hotter than boiling water.
Let me find some on shaking after PC now.
Quote:
wygram said: There will usually be some moisture visible on the glass or in a bag after PCing, also the grains at the bottom might be more wet. Shake after taking the grain out of the PC and after a day or less the moisture should re-absorb and even out.
That is, if you are correctly preparing the grain. Letting it dry before loading into jars and allowing the PC to depressurize naturally until the metal is just warm to the touch.

Tmethyl said: After they are PC'ed you shake them up to redistribute the moisture, it's normal for moisture to be in the grains after PC.
The discoloration on the outside of your jars is mineral deposits from your water, also normal, adding a little vinegar to the water before running the PC will prevent the minerals from sticking to the glass.
And lastly, smoke a huge joint, and chill.

OP, looks like WBS that's just come out of the PC hot Shake the shit out of it, let it sit overnight. Shake it again the next day before you inoculate and then shake after. It'll reabsorb a lot of that moisture As long as they were at proper moisture content before loading into the jars, they'll be fine

filthyknees said:
You also advise to shake the jars couple times a day for a few days? Huh? Im confused. When is it advisable to shake a couple times in a day. Maybe thats a tick you have as a grower, with the proper moisture content i assure you you shouldn't be shaking your jars over days to even out moisture. Who has time for that.
I said a day sometimes 2. Get those panties unbunched

Since you said you would post links I thought you would but ok?
Read the pussyfart quote in your second to last post. He is expressing my point.
Im sure many people have had an inch or two of water up their grains jars, like from personal experience. until you provide a recent post with a link from someone knowledgeable saying water is not to touch grain jars during PC i have no choice but to believe its totally fine. I'm not saying rr didnt say not to 10+ years ago but if you got somebody credible recently saying grain jars cannot be pc'd sitting in a inch of water and i will mail you $5 and unbunch my panties if misinformation can be laid to rest.
Lets wait for others to chime in.
Yes everyone knows its good to redistribute moisture, not to shake multiple times a day for days. To say yup from someone asking if they should do that is a little over simplified.
I only shake once the grain has been inoculated. I know people who do spawn bags and leave them on a shelf for weeks without a shake and they are fine.... If people have a fucked up moisture content yeah maybe shaking it could help but if they need to shake it shows the moisture content it wrong, as seen in RR's jar turning test to check for stuck grains.

I already admitted that the water up onto the grain jars isn't a big deal.
Tbh I always thought it was.
Which would make sense since boiling water is less hot than Steam. Idk I'm probably not 100% correct there.
Do you think shaking a few times a day is going to hurt the jars at all? Nope. And it helps to distribute moisture.
Who cares if it's over simplified? Which it's not because it's pretty hard to oversimplify shaking a jar up.
I don't have time to post all of those links, it would take me twice as long.

I have perfect moisture content in all of my jars, and shaking still helps me distribute moisture.
Please read all the quotes that I posted on it.
Haha glad we could work it out

If the inside of the PC is 15 psi, then all of the water inside is going to be about the same temperature (250° F) it doesn't matter if it is in the liquid phase, or gaseous phase. If anything, the water will be just a little bit hotter since it is closest to the heat source.

Isn’t the water and the steam inside the PC the same temperature? 250f @ 15 PSI? Isn’t RR saying he only restricts water from touching pint jars so water doesn’t splash inside? This is why he doesn’t mind so much with the water coming in contact with quart jars?

I suppose this would be right, liquids boil at a higher temperature under pressure. Idk what I was thinking.
You can make water and alcohol boil at room temperature if you put them under an intense enough vacuum
Must have been old bad info I had read somewhere.
I might try my next PC cycle with the water up the jars a half inch or so, it would keep me from having to use jar lids that rust and make my pressure cooker look crappy...

When i PC my agar I bring the water level up to almost even with the agar inside the bottle. helps with boil over.

I always PC at night and just open it up the next day when I get home (or get up). Nothing works for me if I am trying to do things fast.

If you do 120 mins at 15 psi the jars should last for a couple weeks in the fridge.
It's best to inoculate as soon as it's completely cooled off, and the moisture fully distributed

I've never waited that long or looked it up so I wouldn't even know. Lol
I usually knock up right away.
You're better off putting them in the fridge though if you going to be waiting IMO
