Mason jar lids sucking in

[biggerbud420]

I had my stuff in 32 oz Mason jars for about a month and half now .I noticed the other day some of the jar lids are like puffing out in the center and some are sucked in in the center. What cuase this ? My smoke seems fine

Month and a half? Is the stash cured smoke? Do you burp the jars?

Guess it's cured I dried it for 7 days then jarred no I don't really burp them everyday smoke is fine tho humidity in the jars between 59 na 64 that's between 24 jars

Not sure if u can tell see how one is sucked in and the other isn't

Means the weed isn’t properly dried and building up CO2. Sure when you open the jars they’ll pop.

You mean the ones that are not sucked in ?

Yeah.

I think a sucked in jar is because of a decrease in pressure, which can happen if the jar heats up and is now colder (which is what happens when canning). Why not just burp all the jars (which you should have done while curing)?
