I just used up the last of the outdoor Blueberry I bought dirt cheap. It is about 2-1/2 years old and it made some really good oil (QWET). It was never frozen and not well stored in the first year, before I bought it.
If you purge the jar with nitrogen gas, cap the jar and vacuum seal it with a pump and seal. Keep the jar in the dark.The bud will last a long time without light and oxygen.
Mine never seems to last very long lol between juicing eating vaping smoking and infusing it’s gone in no time plus i have also been known to help other patients down on there luck out
