Opinion on cooling jars
    #25587828 - 11/02/18 08:33 PM (6 years, 2 months ago)

I had been having issues with jars failing without ever being opened after a pc cycle, likely my filters were to blame so now I have several plastic lids with a full sfd underneath (courtesy of the man) and many metal lids that I pulled the poly out of and siliconed a quarter sized sfd over the GE hole.


I'm shooting for overkill here and once I don't have the issue anymore I will start slacking up a bit.

So here's my question: Would it be "safer" to let my pc cool on the stove as is overnight, let my pc cool in front of my running hood (which is gonna take forever), Cracking my pc open in front of my hood and remove the jars in the airflow and let them cool sitting outside of the pc in front of my running hood, or since I plan to keep the jars in an unused tub (styrofoam cooler to be precise)just taking them out hot, setting them in the cooler and slapping on the lid?


I know for most people it doesn't really matter but again; overkill. Since I've been having so many issues. What say you mushroom folk?

I don't think the issue is coming from how you're taking your jars out of the PC, or from where you're keeping them after they're out. Therefore, I don't see how improving those two things is going to prevent contamination. :shrug:

1. Are your lids screwed on all the way?

2. Are you covering the lids with foil in the PC to prevent water from dripping onto the top and through the filters?

3. What EXACTLY were you using for a filter then AND now?

4. What kind of spawn are you working with? Rye, Popcorn, WBS, BRF?

5. How long are you running the PC cycle while at 15psi?

We need some more info. because I highly doubt the problem is originating from you opening up your PC after its cycle.

***EDIT***
I see you've been here a while, longer than I have.  Maybe you do have some qwerky issue here. I was just addressing the basics.

It was my filters or my lids, likely my filters. I run 15psi for 120mins with oats.


It's mold that's ruining jars, mold is relatively easy to kill in a pc cycle so it's getting in after sterilization.

Without ever opening the jars after a cycle they develop mold, there's nothing else it could be besides my lids or filters.

All I'm after is what would be the "safest" way to cool my jars even though I now have sfd's. both full ones and quarter sized ones. Most people can take their jars out hot and sit them on the kitchen counter and be good, my situation is different either because of my lids or filters.

Maybe since I changed my filters to sfd's and am trying full sfd's with plastic lids I may be able to sit em on the kitchen counter while still hot too but I would rather go overkill and slack off little by little just to assure that I finally have a grow without fucking issues or lose my next tub right as it's about to pin

Putting your PC in front of the flow hood to cool would be overkill alright.  That's fucking crazy.  Just let the PC cool on the stove overnight.

It worked before, right?

Why would it stop working all of a sudden?

Honestly maddchef, I've always been a follower of letting them cool in the pc overnight, although I have unloaded jars hot and flowhood cooled in the past when I was in a hurry to get grain jars inoculated....can't say that I have had better results either way :shrug:

Nah I've been having the same issue for a long time. Only recently I actually gave enough of a fuck to spend the time to properly track it down.


Yeah there was once upon a time about 5 years ago I got by with taking them out hot and letting them cool on my kitchen counter but in my present situation, spore load, likely shitty poly filter making, etc. I can't do it anymore.

Like I said I'm sure I can get away with much less since I switched to sfd's both big and small and am using someone else's lids that they made and were kind enough to let me try BUT....I'd rather essentially nuke an anthill so that I can finally have a grow with no immediate issues and then I'll slack off from there

Could it be the grain?

It just seems weird that polyfill wouldn't work.  Ive used it in unclean conditions fine several times. 

Anyways, I feel for you, tracking down this kind of thing can be stressful, and so can not having mushrooms.

I don't see how it could be the grain when I had a full batch of 7 jars left in the pc after a 120min cycle and left to cool naturally acquire mold from the top (filter area) down. The jars and not even the pc itself was ever opened for 2 weeks

Agreed

But mold getting up under the weight on the PC then through the filters to the jars...on all 7!  That's gotta be an unlikely scenario too.

That top down growth could perhaps be explained by the re-oxygenation of the jar, which comes from the top.

Just sayin'.

I think you should do what seems right to you.  Put the PC in front of the flow hood.

I know it seems like an odd and extremely unique and rare problem, I get it. Hence why it has taken me so long to figure out the issue. I'd even run a batch and let them sit for 2 weeks or so and wouldn't see any contamination so I figured that wasn't it and I would toss em and move onto another variable.

Not every jar does this though and all my lids and filters were made the same aside from the fact you cannot stuff poly exactly the same on every lid, you can try but it's always slightly different. I've closely looked at the aspects of the jars that failed vs the jars that were fine and visibly they look the same.

I'm relatively certain the switch to sfd's will remedy the problem. I may have to use full sized sfd's with plastic lids opposed to the quarter sized ones siliconed to my preexisting metal lids but that's what I'm testing now.

To this point I had always used only poly lids and once before I had questioned my filters I simply tore out the old poly and redid them with poly. That does no damn good if I'm not making my poly lids up to par ya know?

I feel pretty stupid for not trying switching filter material before now but I've had poly filters work well in the past and really how hard is it to stuff some poly tightly in a hole? So I was arrogant and figured no way in hell I could be messing up something so simple.

Alright well I just stuck the pc in front of the hood for a few minutes until a few minutes after the pressure dropped. Wiped out my styrofoam cooler with ISO pretty well, popped the pc lid and put em in the cooler with foil still on them. The lid fits relatively tight.


I know it really sounds like some noob shit to do lol but I'm desperate for a victory. Between all that and the new filter/lid combo something's gotta at least help

I do remember pasty or someone of his stature telling me once they had a problem for a while and storing their colonizing jars in a "clean" tub helped to some extent. I think they were having issues with a large sporeload assaulting their filters and some were still getting through. Can't remember who it was though.

Thanks guys.

I cool my jars while still in the pc. Move it off the heat and sit on hot pots to cool on the counter, not in front of my flow hood. I have always used the synthetic filter disks cut and glued over a hole in the lid, this works best for me. My jars colonize in a little used room that is sprayed with Lysol 2-3 times per week.

No I'm not using a syringe. Also the issue at hand is jars contaminating without ever being opened, inoculated, or otherwise screwed with.


I have a few experiments going at the moment.

#1 4 jars: Plastic lids with a full sfd underneath

#2 4 jars: Metal lids gasket side down with a quarter sized sfd glued over a small hole in the lid (previously stuffed with poly)

#3 4 jars: Same as #1 except I left the foil on loosely

#4 4 jars: Same as #2 except foil left on loosely



All jars were inoculated from the same plate/same culture and I left one jar untouched out of each batch as a control.

I let everything cool in the pc naturally just sitting on the stove.


These were done on the 4th-5th. It was taking around 3 weeks for me to see growth in the unopened jars prior to me changing filters/lids so I should have some sort of tangible results by the end of the month
