Fermentation lids

[Optimus913]

I am buying some for my Mason jars for fermenting some pineapple juice to feed to my Maui Waui's in the last week of flowering.
Got me thinking, could you use these to cure?
They allow co2 to escape and oxygen not to enter so you don't have to burp?
Seems too good to be true

I don’t think they’d serve any purpose. As far as I know the bud doesn’t produce any CO2. Or if it does it’s so minuscule that it isn’t going to be a factor. I’m assuming that valve function on those lids will rely on a certain amount of pressure from inside the jar. There is no such pressure.

I’m not sure that bud off-gasses much of anything while it’s curing. If it does offgas- I don’t think it’s such an issue that the jars needs constant maintenance to control the situation.
The ‘burping’ routine is mostly just a good way of bringing your bud to its final state of dryness. I’m not convinced that there’s much need for it beyond that, but I could be wrong. I’ve never been able to tell a difference between bud in jars that were opened regularly, and bud that was just thrown in there and left for months.

Found this, question now is does it produce enough for fermentation lids to work?

So say the experts I guess.... I’ve never In my life seen any evidence of pressure building up in any container of bud ever.

I store my weed in screw-top jars. I have around ten of the one gallon size and two or three dozen smaller ones. Most of my bud has been dried, thrown in with a boveda pack and then left completely untouched- often for months. I have mason jars of bud that are five years old. I’ve never once seen signs of a convex lid or heard that ‘pffft’ sound of escaping gas.
I brew wine and do a lot of canning and fermenting so I’m familiar with the idea of CO2.
I’m sure there isn’t going to be enough from the bud to make the fermentation lids work. Something like Kimchi making where I do have to burp the jars- they build up some serious pressure- and that’s the type of thing these lids are designed for.

Thanks for the info.

I like vac packing, because even if its a lil too too moist, no air means no mould or anything to kill it. Humidity not so much a factor...I do like those boveda packs though....very cool.

So you don’t have Mold issues? Burping is crucial to a clean cure from what I’ve heard and seen. 5 year old Mold might kill you hahaha

No. Mould can’t live in conditions of low humidity. I dry the bud within range before jarring.

Burping is a great way to finish drying bud when you don’t have a hygrometer and aren’t sure how dry it is inside the jar.
Fresh dried bud from the drying rack/box can appear very dry, but often it’s just a surface dry. Stick it in a jar for a while and the moisture level evens out. Sometimes the bud that you thought was dry and crispy was actually moist inside the stems and inner buds. Left in a jar for a day and the whole bud feels soft and moist. So it needs more drying. Open the jar or take it out for a while to dry more. Then repeat. Till you reach the moisture level you want. Aka ‘burping’.
In the days before we had access to cheap little hygrometers and boveda packs this was an essential process.

Is it still essential now? Well it’s obviously not ‘essential’, since I can’t tell a difference between burped and unburped bud.
It’s totally possible it could be beneficial though, because of the ‘offgassing’ or whatever, and I just haven’t noticed the benefits.

It also could just be mostly a myth -like that MaxYields blurb about the pressure building up. They’re just repeating something they heard somewhere. I’ve seen growing ‘facts’ repeated for years, till they start getting proved wrong and then slowly people stop blindly repeating them.

A few years back every article on taking clone cuttings used to insist that you cut the stems underwater and/or immediately put them in water after you cut them, to avoid getting a dreaded ‘air bubble’ in the stem. You still see that nonsense repeated but it’s starting to die down. .
I did a side by side test with cuttings and there was zero difference in rooting or health between clones cut underwater and ones that were left laying out completely exposed for 30-45 minutes after cutting. A myth. Burping may or may not be a myth but I’m keeping an open mind.
