Long term bulk storage.

I was wondering, what are some good and cheap ways to store large amounts (ounces or pounds) for long term storage? I've heard that vacuum sealing is a good option but a friend also told me that if it is kept like that for a while it begins to compact and turn to shit is this true Or will it just spring back as soon as you open it up?

It will not always "spring back up", but you will be able to seperate the nugs and sort of fluff it up after youre done storing it. Ive gotten some in a brick that just would not spring or fluff back up. Also, you can get a vacuum sealer that wont totally suck all the air out so your nugs wont be so crushed, but with more air in the bag that means shorter time you can store it.
