weed does lose potency from age but it takes a long time if stored properly.
Many folks cure it 6 months or so before smokin any at all.
In the curing process it gains potency. I have not personally observed the difference in potency from curing this long but I have read it, and believe it as it came from a reputable source.
It will be quite fine for longer than youll problably be able to keep it before it degrades.

Peace.

btw its not a dumb question. It has been asked a lot here but certainly not dumb. Seeking knowledge is the most intelligent thing to do!
There is a search engine on this site that will help you to answer some of the generic questions you might not want to post to ask.
But, when in doubt...ask!
