I heard the best way to store long term is:
Vacuum sealed mylar bags, but throw a chip of dry ice in there before sealing it.
The dry ice melts and evaporates to become CO2, which means the herb wont oxidize.
Then store it in a cool, dry, dark place, with little temperature variation.
From what i hear, this makes herb last years.
Just keep it in a mason jar in closet or somthing, itll last forever
Dry ice is easy to find. I havent done personally, (my weed usually turns into vapor or smoke pretty quickly, no need to store it long term) but i read about it in Cannabis Culture magazine, which is a source i trust. The guy who wrote the article had tried several ways, and he said this worked best for a several year storage. For months, i'd just do mason jars.Have you seen this done?? is it hard to get hold of dry ice??
I have smoked old weed and it tasted like the brick weed I used to get. It was purples and other great strains, stored, dry and vacuum-sealed from 2006 to 2009. Its better to sell, smoke and get properly cured stuff when you want to blaze it. I do like the dry ice idea and will be trying that soon!!
Well, mine expires when I chop it...with a sigh of....now burn me dammit!
