why are air pockets during sterilization unacceptable in bags, but fine in jars?

Because jars don't inflate and pop, would be my guess. :shrug:

air pockets in a sealed bag can lead to air/water expanded as steam and popping the bag. un-sealed bag who cares. jars are vented.

If a jar is properly sterilizing, steam should be forming on the inside of the jar and pushing through the filter, purging the air from the jar.

A bag that is folded restricts airflow to the filter or even out of the bag when
the water in and on the grain begins to steam. Less air to push out the better.

Partial pressure of mixed gases says that a mixture of gases at any pressure is
a combination of pressure of all involved gases. You need 15psi of steam pressure
but if there is air in the bag then the 15psi is a combination of air and steam pressure.

Basically air pressure might be at 5psi while the steam pressure is at 10psi so you're really only sterilizing at 10psi.

Definitely because of inflation and popping too

God damn... I'll make sure check to before I submit a post. I accidentally changed a thread title a while back and didn't realize it until someone pointed it out.

Ah, forgot about the steam purging the jar of it's air. Thanks! That's what I was looking for. So the air does get purged in jars, but in bags we just have to help it out a little more.

edit: and thanks for your bag write up, nate! I just finished rereading the thread actually.. I've had a shithole of a time with bags but think I'm dialing it now. AWESOME tip about unscrewing the black cap to the jiggle weight and putting washers there instead of quarters. my quarters constantly get off center and it just leans to one side. will fix once they're done running :-)

Proper venting is very important, I believe this may be one of the primary reasons for early contamination with inexperienced growers; that and improperly hydrated grains. I could be wrong but it seems reasonable based on what I've seen.

Yeah, I just wasn't sure how the air was actually leaving the jars and not just chilling out. But Nate's right about the steam shoving it out. Kind of interesting that you have to vent long enough for the grains within the jars to steam sufficiently so that each jar has been purged (and then vent that air out of the PC), I've only ever thought about the air outside my jars being purged.

Might be cool to drop a suitable thermometer inside a grain jar to get an idea of the temps after 10 minutes of venting.

Small talk,
I've had a serbica tub outside for four months with nothing happening yet. Hoping maybe this spring will bring me some luck. As for hispanica I've been messing with it for about 6 months and having a lot of difficulties what I believe is probably genetically because ever culture I get that looks halfway decent slows to a halt on grain and on bulk. I'm still trying though. Hopefully one day I can get some different genetics on the plates though. What did you want to know?

So my ape swabs were clearly contaminated. I put different varieties to agar in the SAB at the same time and they are all looking lovely so far.

Would you attempt to save these? On the top one I see a hint of clean myc. Anything on these you'd transfer now or should I wait a bit?

I have 2 others that look similar, if I had more APE I'd just chuck them but I want the challenge.



By the way, if I'm using this thread for stuff that should be in more targeted threads let me know and I'll stop spamming it.




If nobody answered the clean myc on the first one is what you want to take, if you didn't. :cookiemonster:

Pretty sure that bod put one in his pc to test internal temps with different vent times.

Read in a post here, the tint of MonoTubs is sometimes difficult if its nur clean-trasnsparent.



Do you guys think these boxes are a problem?
The lid is not in this greenish tint, the lid is just transparent.

You can try cutting out the section with trich growing and using iso in the hole to prevent it from coming back. I've done that with about 50% success. It doesn't get rid of all of it, the trich WILL come back, but it can buy you some time to salvage a flush. Obviously the sooner you catch it the better, but if you cut down into the sub and see that it's trich all the way through, it's trashed.

Shouldn't be a problem, other than maybe giving you a slight panic attack when the myc first pops through the sub and you think it's the mean green :lolsy:

Haha yeah, thats true, everything is looking a bit greenish, even pure-white myc (if you look at it while bright light is shining to the box)
