I discovered early on that the smaller you cut the buds the faster they dry. I now cut each individual flower bunch off and dry like that....I've had success using small buds and layering them lightly in the jar. You want lots of surface area.
The surface area got me thinking of something to insert in the mason jar (that I could fabricate) and then I figured...check Amazon. Has anyone had any experience using one of these?
