Will they hold up to being used for FERMENTATION of greens/ vegetables like cabbage not in the fridg when pressure buildsup at room temps ?

the jars are very substantial, and the closure is tight and very sturdy. I have not used for fermentation but they might work. I would check with the manufacturer

I have used these bags for all sorts of things, including kale and leafy greens. My experience is that things like kale and leafy greens don't do as well, as they need something something more airtight to stay fresh. They can begin to wilt after a day or so. Things like apples, citrus, potatoes, onions, etc are great in these bags.

I use them for my dry foods like rice and beans on the pantry shelves. I'm not sure how they'd do in the freezer or the fridge.

I don't think they are damaged. I would strain it off, begin the second ferment and start a new batch with the grains. It takes a bit for the grains to adapt and get up and going, and trial and error to find your preferences, but they are pretty fool proof. I wouldn't worry about them, but I do recommend joining a group like https://www.facebook.com/groups/358190800919913/ for lots of good ideas and advice.

it depends what your fermenting I didn't need weights for fermenting cabbage with carrots you fill the jars then also fill the tubes on top of lid with water air bubbles and liquid will leek out as you ferment foods check jars each day you will have a mess to wipe up.

I imagine there is a point when any bottle has the potential to explode. I used these for kombucha and they remained intact.

No, they don't. But they hold together very well. Have them in an inch or so of water for 2 or more weeks while my lettuce, tomatoes, or spinach seeds germinate and are ready for planting. No problems.

They are very good to use as canisters. I would not put them in the freezer.

They are pretty sturdy, so I believe they would handle something hot, just not boiling hot.

Hi, I use these for anything...what I do if I'm not storing produce is merely take out the vent in the bottom, and it works great! Hope this helps!

Don;t see why not--it was designed and created for making sauerkraut and other fermented vegetables. Give it a try.

These have an open bottom. I use the small glass weights to keep the veggies under the brine then put on the ring and the flat lid with the ferment which goes through a rubber gasket in the lid. Fill the fermenter with water up to the fill line and check periodically to see if more water is needed. They work great. I've made sauerkraut, dill pickles and fermented lemons so far. All came out very well. I'm trying Kimchi next and fermented beets.

It would be not be a good idea for 2 reasons.1. You need a larger container for the Kombucha colony to grow.2. Kombucha needs access to open air that is filtered through linen such as cheesecloth or a thin towel. The air lock (Fermenting lid) only allows air to escape :-)

Not really. They keep air out. They will not keep pressure in the container-it will go flat

They are air tight. I use them to store yeast and have never had a problem.

No, you don't need a weight ! Sometimes I don't even have all the vegetables below the surface of the brine. It's the contact with oxygen in the air that enables molds to grow (and when I ferment with a crock I keep the ferment under the brine and weighted, but still have to remove mold every few days) - but these caps prevent mold because the air lock enables the CO2 to build up in the jar, which prevents mold from growing. BUT, know that you can't check the contents, so you have to guess as to the length of time to ferment. I put a date on the jar so I know when it was started. Of course, if you need to ferment it longer you can always go back to the weight - in my experience, I haven't been able to use the cap again with the same ferment, probably because after a certain amount of time, the production of CO2 diminishes too far. Still, I love my 'Kraut Kaps' - they're neat and easy !

I think if you keep them refrigerated they will be okay but I let the company mange that and order in the spring! So worth it, I had no bugs on my veggies or flowers.
