Storing cured weed in a vacuum chamber.

[toketronix]

This is probably the wrong section, but there are many people in here messing with vac chambers so...

Been looking at various non plastic methods for long-term storage of cured buds, somebody suggested a vac chamber.

I'm wondering if storing buds this way would effect the weed adversely, eg mess with the terps/oils etc.

Thoughts?

shouldn't have any detrimental effects on the buds, terpenes and so forth. i have bud vac bagged for a couple years that smoked as well as the day i bagged it so i don't believe it would hurt in any other type of container.

I think a vac chamber has bit more muscle than a food container, eg under normal conditions it's said that THC boils around 315F but in a vacuum of -29.9196″ Hg, THC will boil at 23F.

sounds interesting and might be physically a correct approach.
have you got any kind of reference regarding the low temperature boiling?

boil to where? i wouldn't vac it for any longer then a couple minutes, it's not like vacuuming a refrigerant line, where the moisture is released out for 10 to 15 minutes or more.

i use a professional grade vac bagger cappable of hitting 28HG but i don't leave it hooked up for any longer then a few minutes.

I don't fully understand vac chambers hence the thread, ....but after the pump is disconnected the buds are still in a vacuum ergo the boiling points are altered?

I don't understand the question, where does anything boil to?

boils out through the vacuum pump, if you let it on too long, but my point was if you don't do that it has nowhere to boil off to.

yes they ideally will still be under a vacuum, whatever level you took it down to to begin with. which is why i mentioned not taking it down too far to begin with. the terpenes should not boil off if you vac it for just a few minutes, if you let it on for longer it will begin to do that and subsequintly gum up your vacuum pump as well.

the only down side to vac bags is they tend to compress the bud quite a bit, kind of like brick weed, but the potency and flavor is still there.

wanted to add that i have even planted seed that was vacuum sealed with great success and i vac all my seed stock now without issue.

I think the point I'm trying to make is: a vacuum will remove the bud damaging oxygen, but in doing so might make the terps/oils more volatile therefore the buds might degrade in a different way.

which is why i mentioned not taking it down too far to begin with. the terpenes should not boil off if you vac it for just a few minutes,

Check the criteria in OP.

you have to understand something about vacuum and 29.92 inches of mercury, it takes a very long time to vacuum something down to that level, if at all.

with that in mind i would just shoot for high 28's on your equipment, that's plenty low to maintain a good vacuum that will preserve bud.

I wonder how buds would fare after 1-2 years at 28's.

Examine before and after looking for burst trichs.

they fare very good like i mentioned, as far as potency and flavor and your chamber idea may preserve texture as well, although i have no idea if your terpenes will end up on the chamber wall or not...

Examine before and after looking for burst trichs.

trichs can burst, but they shouldn't degrade since there will be little left to cause oxidation. that being the point of vacuum storage, little to no oxidation.

Those two bits of bold directly contradict each other, the general idea behind preservation is to suspend state over time, not to disintegrate/change the material being preserved.

i don't feel they do conflict, i said the flavor and potency will be preserved, but in my case using vac bags it tends to compress them like mexican brick weed. i personally don't care about that, but others may.

with a vac chamber you could end up distributing your resins on the chamber walls though, but i have no idea if they will or not. try testing a small bud and see how it goes.

Can you explain how terps/oils becoming separated from buds to be smeared on the chamber wall is good preservation?

Please stop trolling the thread & only answer when you understand the question being asked & have something useful to offer.

i didn't say it was and never claimed i used a vacuum chamber. i mentioned i used vacuum bags and they worked fine, as far as vacuum preservation goes.

This is a thread about vacuum chambers not food bags.
