This drying method suits me and I consider it the best in my opinion. I believe that the flower extracts juices from the leaves until the end of drying.Why don't you trim before drying?
How long did you dry the seeds? How much in the freezer were they?
Then don't forget to dry a minimum of 4 weeks. After that, you need to put them in the freezer for 4 weeks, then in the refrigerator.these are seeds collected from cut plants that have not yet been dried.
