Weed Preservation

Whats the longest you can preserve weed with it still being good?
And whats the easiest most compact way of doing it?
Planning on going to Phoenix soon wanna buy my weed before I go but not to sure exact day im leaving. So I need ideas.

I suppose it depends on a few things... For quality I would go with vacuum sealing some mason jars and storing them in a dark, cool place. If you do this it should last a very long time. Exposure to air, heat, and light degrades THC. Remember though, fresher is better. If you are just wanting to take a bunch of regs with you, get a trash compactor and put as much weed as you can in a garbage bag and compact it. That will compress it a lot.

Well I dont got a vacuum sealer.
P.S. How can you vacuum seal a jar?
But would normal jar work with tight lid seal. Im probably leaving in 2weeks I just want something that for sure could keep it almost same as day I bought it for a week. I aint buying a huge quantity just enough to get by 2-3 weeks.

glass jar with a cork lid or freeze it. dont leave it in hot places and inthe sun and ill will be fine.

Aight, so if I were to put in a jar and in freezer for couple days I should be all good?

yep if its only for a few days then a sealable baggy will do

Like the other dude said glass jar out of the way of light and heat.
