Vacuum-Sealed Weed

I vacuum seal all of my harvest in mason jars with a Pump-N-Seal. I've been doing it for many many years and it works great. If you don't open them and keep them cool and dark, they last for years. I'm currently smoking a jar from a harvest that's close to 5 years old. As strong as the day it was sealed, and the aromas are much more intense and complex.


Dj short has a huge stack of test results from the wercshop, in wa, that demonstrate the changes in terp and cannab profiles over YEARS of cure time. Talk about blow your mind!

Best Way to Go...

I vacuum seal my buds also, but have mostly used plastic vac bags for this purpose. I find that even after 4 years in proper storage the medicine is almost as good as when sealed.

Glass does a better job of allowing the flavors/smells of the medicine to remain intact, but if properly cured before putting into plastic you will still have a tasty and potent product even after years of controlled storage.

One thing I have noticed is I don't like to pull a strong vacuum on my buds being placed into plastic bags seal a meal bags as it will crush the buds and distorts how the medicine looks, not sure if anything is lost but I do it mostly for bud appeal and the ease of handling when your ready to enjoy you aged medicine...

Medicine put under a vacuum seal after a proper cure and stored well, I would think 5+ years would be doable!

I just ordered a jar sealer attachment for my B&D sealing appliance. And some oxy absorb stuff - someone from Oregon, on another board, mentioned using the oxy absorb packets in his jars of herb, and how well that works.

I currently use C-Vaults for "long-term" storage.

I use the jars and the bags, buds in the bag last for years (4+ for me)

I use the bags for the longer branched buds that I don't want to break up.

just my 2 cents, but i really love smoking frozen pot. Even small stems burn to a fine white ash. And, the smoke is cooled through the herb. I don't even break it up (much), I just crush the bud down and compact it into a joint, maybe crush out the stem and twist it up.

Straight from the freezer it cools the flames and keeps you blazed up and soaring high.

Someone said it fucks with the molecules, I have no idea if that's valid or not. I just know a fridge and freezer full of weed has made past winters here and there bearable.

No, I have done it before without using a vac sealer, but you do need to make sure it is dry.. Also, humidity is relative [to temps] so if you bag in 90%RH @ 30 deg, you will get condensation when that drops to 20 let alone 10... could be an issue for some people in humid places :)

Not sure if you met THC123 the other day, the guy is a mine of useful information, this thread he just posted may also be of help. https://www.icmag.com/ic/showthread.php?t=261703

Thanks for the tip and the link. Both very useful. Mostly things went well with some good smells to come home to and some very well cured bud. :biggrin:

I ended up putting everything in Mason Jar's. Then I scattered rice and layered ripped up newspaper in the bottom drawer of my fridge. Also put a could of open packs to bicarb of soda on the top to help keep RH down and smell out.
I'd tested it beforehand and the temp tip allowed me to try and get the jarring room as cold as possible with similar RH to avoid condensation. This also worked well enough that I'm considering buying a mini fridge in which to keep my stash!

There was one weed I had to chop at the last minute. It was 7-10 days off being finished. I ended up using various different drying techniques including putting it in a basket with a fan attached for several hours and eventually in the microwave between 2 sheets of paper towel!
I think I overdid it a bit bit to be safe I put some rice in with it in the jar as dessicant and to be fair it turned out pretty well. The bud is overly dry but well formed and not dusty at all. It smokes well and even has a little mango smell and flavor although to be fair the smell/taste is poor, especially compared to what it could have been if it had been allowed to mature, dry and cure as normal.

The other 4 kinds have matured very nicely which evens the scales a little. :ying:

The way smell/potency/effect seem to change over time cured is an interesting subject in itself. The richness of the smell of my critical jack herer alone compared with 5 weeks ago is enough to make it a worthwhile exercise. However the real benefit seems to be easily quantified as it seems the effect can change over time with the cure.
For example with my critical jack herer there is now a much more noticeable head stone along with the nice happy high compared to 5 weeks ago when there was only the happy high.
Is this some kind of placibo effect or is there real science to explain?
(My apologies if this is an obvious subject already but it staggers me just how little seems to be known about weed and weed related science like just this kind of thing. Surely it could be very useful to know and possibly manipulate so weed can medicate more correctly more often in the future.)

Anyhow (takes deep breath). Panic over. Time to party. :dance013:
 
It should last at least a few years when under nitrogen gas without loosing potency..but there could be still some degratation processes, haven't looked much into it.

I agree with Pipedream in posts 3 and 5...
I too, have been using a "weedsaver" also known as a foodsaver, for many years. (since the early 80's I think)
The one I have now is so old the heating element for sealing bags is burnt out, but that doesn't matter. I never used the bags, since they crush your buds flat, but the jar attachment will vacuum your personal stash in mason jars..Ive opened jars 2 years later that were like the day I vacuumed them. Jars that Ive opened 4 years later still had the same smell and potency, the buds have just gotten a little darker, slightly browner, and I think that's due to light infiltration over the tears. I plan to spray paint the outside of all my jars black next year, which should keep out 100% of light.. I just store the quart jars in their original carton in my closet where they stay between 60 to 72 degrees all year 'round..

Vac sealed mason jars are great for long term storage. If mailing herb, I vac seal the buds inside a cedar cigar box, that way they don't get crushed.

I have a foodsaver with a mason jar attachment...so can seal the jars...I have jars 2 years old that are just like the day they were sealed..the vacuum takes most of the oxygen out which is a oxidizer...so void of oxygen the weed stays fresh like day 1...I have a small wine fridge that holds 20 half gallon jars..temp is set at 55 and works like a charm...can get one for around 250.00..best storage contrapition going..lol...open a jar..fill a smaller one..re seal it..fridge it....nice...

either way it will turn browner.. its the chlorophyll degrading.. makes for a smoother smoke either way.. and painting jars is over kill just keep the box you get the jars in.. put back in the box.. and if your worried put another box over the top to cover the light. or just toss jars into totes.. but either way it will still get browner natural process..

Jars work great for personal stash. Heat sealed Mylar bags and 5gal buckets for multiple units. Throw in oxy absorbers and seal pails with gamma seal lids.

Hello all,

I wonder if mold is inhibited under a vacuum?

Also, what about humidity packs in the jars and vacuum sealing?

minds_I
 
Could U explain what Ur doing buddy mate??? How long had the vacuum packed bud been sealed like that?? Do U just open up the vacuum sealed bag then throw it in a hotdog steamer?? Or something similar to regain the normal shape of the product?? Does this affect the taste/smell of the bud at all?? I would love to pick Ur brain buddy mate I have tremendous respect for you man you do awesome things brother.

on alot of vacum sealers theres a manual seal button. dont ever seal your weed to the factory setting unless you like brickweed. dont use a sealer that doesnt have that function.
@ mindsi

no its not a vacuum in the bag. its just vacuuming the air out and shrinking the bag around your herb. if there wereair pressure in the bag that was lower than the air outside the bag it would continue to collapse til that balance was met. it would crush your herb to a brick looong before you reached a true vacuum. it just displaces air.

if done correctly it ca keep herb from moveing by giving it a form fitting bag thus reducing shaking and duff breaking off buds. but if done too much it squeezes and crushes the bud. the polymer dissolving trichs and making it taste like plastic are nonsense it would be brown weed before any of that could happen. in a dark cool spot you have a little more than a year in optimal conditions before its really less marketable than people will accept. the first 3-6 months changes it alot but its still sellable. 6-9 and its starting to fade a litttle but its august so you know......people will take it. out door from last nov in november youre screwed.
the air in the bag does have oxygen and it does degrade the herb. hence the reason for nitro flush. this takes place faster in warmer environments and the more light its exposed to. a freezer or fridge works great as long as you use common sense and let it come to room temp before opening, so air moisture doesnt condense on the actual herb while it still frozen. dont put your groceries on it and dont shove it around looking for your jar of seeds. its brittle and more so at that temp. double seal obviously you dont want it to taste like your frozen garden pesto. dont freeze wet but it doesnt need to be bone ass dry just normal, a lil on the dry side is fine but dont turn it to dust.ive seen people ruin weed vacuuming it to a puck..
