I’ve ran jars all the way from 1 hour to 4 hours at 15-17 psi. I’ve had jars perfectly colonize plenty of times without shaking as well. But the results are MUCH better when shaking under the same sterilization techniques.

I’ve been testing this out a lot over the past few months, with over 300 lbs of dry grains and several different types of filters and unmoded lids too

improperly hydrated grain can be a curse aswell.
and then there is stalling from lack of fae. shaking takes care of that aswell, right?
therefore…. shake it like a polaroid picture

Can you "over-shake", i.e. too much?

Just a quick correction on terminology. Stalling can be caused by improper GE (gas exchange) not FAE (which is what we call it in fruiting)

And I wouldn't say that shaking fixes it. If you're stalled at the last 10% or so then the recovery may get you there but I wouldn't expect a jar stalled from GE to correct without like, more GE.

Hold the phone, am I reading here that people are thinking a shake will risk contamination?

Not the case, it will reveal contamination that may have already been present but it won't cause your spawn to magically pull in bacteria or mold. If people are seeing contamination after a shake it's because it was there all along.

Ding ding ding. My one comment: if you're using unmodified lids, make sure you fully tighten the lid before shaking. If you have a small gap in the lid, you can definitely let in contaminated air when shaking.

You are right, should have been GE.
Thanks for correcting me.

i do think though that shaking does affect gasses in the jar. apart from  moving grains around and creating more sites of colonisation?

i hope your jars are STERILISED not sanitized!!

That is what I meant.
I feel like I need a tiny paint mixer. I don’t have nearly as many jars as the person above me, but that was not very fun to shake all of those.

Hey, look at that. I cracked my comment.
I still haven’t figured out how to do this on purpose, but it even made my signature look more cool.

Wait tighten the lid? I’ve been taking the lid completely off and then shaking to give them more fresh air. Then I scoop them up and throw them back in the jar

I had a SFD that was rtv'd onto a plastic lid come off in the dishwasher.  First that has happened.  It looked like the rtv, which stuck to the sfd, had a good even spread. 

Makes me wonder whether there really is an air tight seal created by rtv.

at this point you can add some honey for a better yield

Yeah sometimes if I'm feeling a bit fancy I'll just say fuck it and spit in my jars
