You tighten the lids beforehand. Remember, you should have filtered holes with polyfil, Tyvek, micropore, etc that allow steam to escape through the lid.

I don't agree completely, when just using micropore tape and tightening the jars ive had the tape get deformed and sometimes baloon out because of the steam. This decreases the filtering ability

With tyvek, or micropore filtering.

I DO NOT tighten jar lids, prior to PC'ing.

I leave then half or 3/4 turn loose.

Then tighten, when I remove them from the PC.

Reason being, if the lids are TIGHT.

Steam develops inside the jars & the only place it has to exit IS.

Through the filter material.

Because the steam comes from moisture in wbs/grain jars.

It can/will carry a small amount of nutrients (from the wbs/grain moisture) - with it.

Meaning, that you can/will SATURATE filters with some nutrients.

Which, can later lead to contaminate spores germinating on the filters, and wicking into the wbs/grain jars.

True, also, tight lids will cause micropore tape to bubble outward.

Not a good thing. As, that expands the pores of the tape.

Which DEGRADES it's filtering ability.

For that matter, I don't simmer wbs/grains - either.

To each his own & whatever works for you - does.

is this in the FAQ's?

Is using the filters really necessary? I really don't want to go out looking for it. Also, my WBS jar got dried within 2 days, the seeds don't even look as wet as they did after taking them out of the PC. Here's what I did differently: I treated the jars like BRF's with 4 inoculation points and only foil to cover. It must be all those holes releasing too much moisture from the jar...or it could be my seeds not containing enough moisture in the first place. I soaked them for 24 hours, steeped them for 50 minutes, isn't that enough??
