Must I wait 6 hrs. to remove PF jars from PC?!
    #12631618 - 05/26/10 11:55 AM (14 years, 7 months ago)

Hi folks,

  I know it's best to wait 6 hours or even overnight (as I usually do) to inoculate PF jars, but do I really have to wait that long to remove them from my PC? I'd like to do 2-3 rounds a day since I can only fit 10 half pints or 2 1 qt. of WBS.  And why can we remove WBS jars from PC as soon as pressure drops, to shake them? Simply a different H2O content? Thoughts?
  Thank You

you can take them out to cool as soon as they are done. You dont even need a PC for PFs just put them in a pot with water and boil them for 60-80mins

shut burner off after done pcing (hour), move them to a cool burner for a few minutes to cool, then release the steam and you can open the lid to let cool another couple minutes, then remove jars carfully and you should be fine..... just dont put the new jars into the hot hot water or they will crack :wink:

I thought they're be a loophole here, thanks the both of you's. So I must wait around maybe an hour to release pressure, move to cool burner 15 min., then remove, dispense hot H2O, cool down PC with cold H2O, add new jars.  And how long can I keep jars filled before PCing W/O seeing cobweb?  I made 1 too many jars one grow and forgot about the unsterilized ones, maybe a day or 2 and got a fast cobweb cake! or could you have a competitor before PCing, kill it, and do fine afterwords? Doesn't seem logical I know, but for the sake of knowledge, I ask.  Thanks again People!!!

When doing PF jars I always waited over night to remove them...why?

To make sure all pressure was released from the PC (naturally,instead of doing so myself and risking getting burnt by any steam left over)

Also,to be 110% sure that the center of the substrate in the jars were below 80-90° F.

If you want to do a whole bunch of jars I'd say do yourself the favor and buy a big PC...I recommend the Presto 23 quart...fits something like 24 1/2 pint jars.Plus if you ever want to move on t grains you'll already have a PC,and one that can fit 7-10 quart jars at a time.Of course AA PC's are of a much higher quality,but the Presto gets the job done for half the price!

If you aren't inoculating, you can take them out fairly quickly after PCing.  But be careful, as they cool they will suck in air.  Even if you have a filter it's still not the best idea to let them mostly cool outside the PC where the jar may suck in contams.

Give them 2 hours then take them out, you should be fine that way.  Any sooner and you may increase your chances of contams or cracked jars from too rapid of a cooldown.

That is not a good practice.  It will cause the jars to begin drying out immediately.  Remember, the jars are at 250F, and if you release the steam, the water in the brf cakes turns to steam and escapes also.  One should always let the jars sit in the PC until pressure has returned to zero slowly on its own.  It's a very good idea to wait at least an hour after that.  The reason is as the jars cool, the substrate shrinks slightly, and this draws in air from the outside.  You don't want to push the limits of a dry verm filter.

For best results, leave the jars in the PC until cool, but if one is going to speed up the process, at least wait as stated above to ensure the highest rate of success.

Another reply from RR stating the opposite of what I want to do!!! My patience has served me well thus far, so I guess I'll wait overnight as I have been doing and grab a bigger PC.  Thanks to all, but I got a feeling RR is the guy to listen to.

I'll agree that RR is the man around here...and not trying to sound like an arrogant bastard but my advice was pretty much the same.

Yeah I kid, I kid too!!! I just started growing fungi this past November and have viewed this site extensively to extract knowledge.  I'm on my 4th grow, with moderate to high success each venture(I net about 7-10 g dry a cake). I have seen 20 people say 1 thing and 20 more say the opposite on some topics, so it can be confusing.  But a little common sense seems to go a long way in this hobby as well, and learning by doing and experiencing can be the best way to learn.  But I'm takin' yer guy's advice and will wait and throw out the skunky birdseed!
        Peace

I know this thread is old
but I don't feel like posting,
imagine that,


when is the soonest that I can take out my jars


How long should I wait for them to cool after I do take them out?
(I have an accurate thermometer)


Can I take out 5 hours if the PC is warm to the touch The PC feels warm/hot to the touch?


Should I just wait till six hours like dude said?
(I can keep my hand on it and there is no pressure).


Can I take the lid off at least?



Its a nasty old PC and I just want to get them out.

If you don't feel like typing it out and, know a link, someone please post me a link to a thread that gives the exact times and temps pretty please. My search function must be stuck in the 80s. I can only rarely find what I need when I search. I guess I should just read the archive more. whatever

My jars have been done for 5 hours and 10-20 minutes give or take 5.
I would feel safer with them on a shelf in a closet cooling because I read that it can suck in contams when it cools.

Leave the foil on.
Leave the lid alone at least until it cools naturally to zero pressure.
Better if it's cool enough to rest your hand on.

So room temperature before I noc pretty much?

I remember seeing the exact temp they should be before nocing.

I just want to get them going as soon as possible
before my crappy filters fail, to give the myc a head start...

Next time I am going to get some real filters before I start..

From what I had read everyone was using tyvek,
then as soon as I am ready to make my lids,
everyone says that tyvek enlvelopes are too thin,
So then I go to look for a tyvek paint suit, couldn't find one.
Now I am here and so on

yes room temp, just because you can touch the outside of the jar doesn't mean the inside is completely cooled...which is why most just wait over night

as i said i usually wait 2 hours, then remove from PC, but i still let cool over night before innoculating.
