Check that the buds are not too damp to the touch before putting them in jars. The branches should also break when bent.
Curing is easy, your mother should do very well:
- put the flowers in glass jars, without packing and leaving a third of the jars empty
- open the jars for an hour every day for the first week
- then, gradually space out the opening periods, as long as it doesn't smell like damp hay (if it does, reduce the intervals).
- After a month or so, there's no need to open them other than to take a few buds to finish to dry before consuming.
Using 62% humidity stabilisers, such as Boveda or Boost, will help the process quite a bit, but will keep your flowers a little damp (better for preserving terpenes). Complete with a little 58% before consuming.
