Leave in complete darkness and very dry conditions for last 24 hours.
The complete darkness will insure everything has moved down into the roots so give it a cleaner taste.
Then dry conditions will make sure it has given its all in trich production to protect its self.
Then cut at the base before it gets any light so nothing transfers out of the roots.
Personally I trim them up straight away since dry time is then only 4-5 days. Trimmings go into container which I store in the freezer to make bubble hash from when enough is collected.
Buds on stems go into a cardboard box which has clean air flowing though it and minimum amounts of light entering.
Checked daily until stem snaps easily instead of just bending.
Then put in jar and opened for few secs in morning and afternoon, If any sweet shows in the jar they are put back into cardboard box. After a week of opening like that then change to opening only once a day, 3rd week only open every few days. This is the point they start to smell nice.
I recently tried water curing and worked better then I expected. In 1 weeks time from cut smoking was as nice as 4 week old air dry/cured stuff. But there was no nice smell. Smelt like nothing and when smoking the smoke to others smelt almost like wood burning.
