You are saying it will work, but terribly and advising others of such like this is a new-best-idea. Less than 10 minutes to drill a case of wide mouth jar lids out and pack with polyfill WILL yield MUCH MUCH faster colonization, but you are stating that, not me.
"But it is not ideal in comparison to if you have gas exchange ports."
OP: Take it for what its worth. This is either a troll, or someone who obviously does not care about knowingly giving advice that is bad in this thread.
I'm not trolling. This will be the last post cause I think we have gone away from the original post.
I DO NOT ADVOCATE LOOSE LIDS. To make it clear They can work. They will work. They are not ideal.
I have made the mistake before of putting a lid onto a jar that had no GE port. I'm certain that if I have made the mistake then there has been or will be or are others out there that have done the same. In which case they will probably search the forums for something along the lines of this post.
They will see it can work and then will hopefully not do it again.
It is a last ditch emergency response if you forget it.
Yes it is basic. Yes it's pretty damn retarded to forget it. But it happens.
Basically to sum it all up
If your jars are full and you don't have gas exchange then just slightly crack the lid. If you have a gas exchange port already and are wondering if loosening the lid is beneficial. DONT. Even one GE port is better than a loose lid. If you are deciding whether or not you can be bothered to drill holes in the lids then DO drill holes in the lids.
All done.

Often they are loose after PCing, so I snug them afterwards.
I don't know why Frank loosens them after the shake. If they are still warm when he shakes them, then I can guess why. He uses plastic lids and if they are tight when hot, they are a bitch to get off once they cool.
I still use the metal lids with rings. I flip the lids upside down ala RR.

I would ask Frank directly about that, but I imagine that they become loose due to thermal expansion. They are tight when you put them in. Plastic/metal expand more than glass. Screwing the lid tight guarantees that anything that is a vector of contamination stays in the jar, and not around the seal of the lid. Loosening the same amount you tightened will get you back to square one when it cools off. I dunno if this is the exact reason or not, but it would make sense to me. I use metal lids with ge ports, face down. I try to make sure that there is no chance of grains getting stuck under my lid. I've tried plastic lids, and I don't care for them. Just an opinion. I like that the metal lids make a seal and need to be pried off. This is an assurance to me that the only gas exchange happens through a filter media (SFD/PolyFill etc)

The scientific explanation as to why it exhales pressure but does not bring it in is due to the metabolism of carbohydrates that is occurring by the mycelium. It's the same as when you brew alcohol.

If something "exhales pressure" without drawing something in, the scientific explanation would suggest it's creating a vacuum.

Probably not. Loosening and loose are 2 different things in my mind. One is a verb, the other an adjective. You can loosen a tight jar lid, and it still will be tight.
Keep the lids hand tight. I can only guess that you have not forgotten to use a GE port lol......

Its more than enough for a grain jar. My grain lids have a 1/4" hole packed with polyfill.

Have you ever done chemistry?
This is the breakdown of glucose into alcohol and carbon dioxide. Catalysed by yeast.
C6H12O6 (aq) → 2C2H5OH(aq) + 2CO2(g)
Now you will notice you have gone from a liquid (which is the sugar) to another liquid (alcohol) and a gas (carbon dioxide) The volume that carbon dioxide takes up per mol is significantly higher than the volume that glucose takes up per mol. That alone creates greater internal pressure.
Problem solved
