Questions on long term kif storage

[samasama]

Hi, I was wondering if someone could enlighten me on the benefits of storing kif for long periods of time? Some people say it does nothing, others say it increase potency... What are the facts?

Also, if I suspect my collection is too dry what is the best way to freshen it up?

Right now I grind up some herb over the first screen, swipe it all around the screen a few times. Collect this way for a few days, do some clean up on the second and third screen, and then put it away for storage.

P.S.
I love my bubble box : ) Is there a way to get replacement screens? I always like to have back ups.

Thanks
