Can dry ice be used for long term storage?

I have to go to the store and get some dry ice for Halloween cocktails… I was thinking that I could take a small chunk of the dry (like marble size) and drop it into a large Mason jar…then screw the lid on and allow the CO2 to sublimate and replace the O2 in the jar -so as to create a long term storage atmosphere free from any oxidation. After that, just leave the jars in a dark place and don't open them at all….

The only caveat is that I don't want to put too much dry ice into the jar and create an explosion when the ice sublimates. Like I say, a small chunk is what I'm thinking.

What do you think?


plausible?

Thanks

Or…Maybe I could put a chunk in the jar and then not screw the lid down…allow the ice to sublimate, push the O2 out and then after the ice is sublimated, I screw the lid on tight and store in darkness…? Would that work? Or, would the unsealed lid allow more O2 to enter while th rice was sublimating?

Just get one of those FoodSaver canning jar attachments to vacucum seal. I have one and it works great. I've got weed from last January. It's designed to work with one of the FoodSaver machines. But, I cut the plastic attachment off the end of the hose and attach the hose to a hand-operated vacuum pump to bleed brakes. (<<link). I had one in my toolbox. If I didn't have one, I might buy a FoodSaver machine with the accessory port to connect the seal attachment. There are also instructions on the internet for converting a bicycle pump into a vacuum pump.

I think that's the better way to do it. Be careful using bovedas with vacuum. There are reports of them rupturing, spilling their salt solution on the buds. Boveda has acknowledged that their manufacturing process can leave air bubbles in the packet that will act like an embolism if placed in a vacuum. I put them in a sandwich baggie (unsealed) to catch any liquid that might leak. So far no problem.

I have a buddy who saves rice and pinto beans in trash can's, He uses CO2 to dissapate the O2.uses a 3lb Check Valve as a pressure relief.......

Dry ice works OK with grains but O2 assorbers are cheap and work a hell of alot better , without the questonable results

But the big issue with MJ is no matter how you store it at best delta9 THC turns into delta8 THC in about 2-3 years

For true long term storage , a extract dissolved in a high proff alachool in a light proff container stored in a cool climate stable enviroment is best

Thanks, great to learn new stuff. O2 absorbers.... I am going to check it out.

you`d be better off doing a super critical co2 extract and storing that in a freezer

or dry freezing your fresh weed and then freezing it at -30

I never have to worry about long term storage. I tend to smoke mine lol.

On a side note:
Dry ice temps, convert D8 Thc to D9 Thc. I remember this from the 70's in an article from High Times. If I remember correctly, they were doing this to increase the effects of "butter" for making edibles.

Most of those little packet o2 absorbers in jerky and the like are shaved or powdered iron. The iron oxidizes and uses up the available o2 in the package.
I suppose, if it's safe for food........
