the age doesnt matter at all if the buds were dry when they were "put into storage"

alot of the outdoor buds you will buy are actually over a year old because once theyre dry nothing can happen if they are kept sealed up

however if it was some wet buds... they may have just hardened out but i would inspect them for spiderweb like fuzz on the outside of the buds

if it was wrapped up, its probably just super dry and crumbly, if it looks alright just try it out and see how it is

ive came across a QP of just nasty moldy buds and the smell was enough to nearly make me vomit, that is the number one giveaway, if there is a rotting dead body smell then you have moldy buds and they belong in the trash can
