if the jar's are sealed I have kept bud at 62% for over a year without losing more than 1% , stored in a cool dark place. if you would be storing for a very long time, then yes boveda pak's are a must. I just grow for myself, so there is no way I can store bud any longer than a year, and even that is rare

on large scale grow's they take the work out of curing, but again it just adds unecessary expense to the grow. I am very frugal (cheap and broke)
