storing marijuana outdoors (once dry)

Ive looked all over the internet and cant very much at all regarding storing weed outdoors, all it says is proper storage keep in fridge or freezer, dry dark area, etc. Well What about all those commercial growers or sketchbags who dont want to keep all of their weed on the property? I know the first thing that comes to mind is burying weed, but Ive found it to be alot more complicated than that. To be able to find a waterproof, airtight container of some sort is very hard. Ive tried burying jars to come back only 3 months later and find that the whole stash was sitting in water inside the jars.
So my question is anybody else have much experience hiding weed outdoors once dryed, Id love to hear some ideas, Id really like to know how to get cheap inexpensive containers that are airtight and watertight and what would actually work. Theres gotta be somebody else on this forum with some experience. I wanna hear some ideas, happy tokin guys.

vacuum seal and put it in a thermos

i hide mine on my lunar base

there are loads of different ways to waterproof containers. look it up on google or something. ^^^ good idea but a little expensive not everyone can vacuum pack easily.
thick drywall insulating plastic sheeting sealed on 1 long seam with some kind of waterproofing epoxy.
or even wrapped in a few plastic bags, each sealed or wrapped in duct tape. jars with the lids duct taped to shit. do some experiments. see what works best after a little abuse.
the other problem with a straight bury after the hang is if the bud still has a little bit too much moisture, it could mould and/or rot. very bad.
i'd recommend hanging until almost dry, then toss it in a jar and open the lid every couple of days for a week or so until the bud is evenly and completely dry. now you can cure it like wine. and ooooh yes it does get better with time. good luck dude.

canning jars with new lids. Reasonable cost and pretty much bullet proof.
