Something I did that seemed to work good for dry bud was to take a paper towel and wet it......then squeeze excess water out and unfold it a little... fluff it up a little as not to have a hard ball, and place in jar....it adds nothing but moisture...and can be reused.
Suess
I dont like the texture my buds get when sealed with a seal a meal. Seems like it squishes them down or something ... makes the texture diff and they dont break up well ... sort of like keeping a bud in a baggy in your pocket too long... just my .02 ..I deff prefer jars
