Ok Im going to try to answer the question originally asked.
Depending on how it is stored will determine how it is when used.

Now I need to purchase my meds usually 1/4 lb at a time since my connection does not live local and i know its months till i see him again. I get them in 1oz baggies and i immediately throw the baggies in a 1qt wide mouth ball mason jar. I been doing this for the past 5 years and i still have some of the original bud from 5 years ago. so long as it is in air tight container and kept in a cool dark place it will last a while.

as to the link above to air tight jars while they will work they are not cheap. for what you would pay for 1 jar that would hold 2ozs liquid you could get a case of 12 of 1qt ball mason jars i reccommend the wide mouth at a local hardware store. they are just as airtight just not as stylish.
