I did my jaring without RH-meters a few years back... but I had time to check my jars all day long.
now I do use RH-meters! is so convenient!
i like my perfect smoke at 62% rehydrated.
I let them cure (two - three months) and then dry them to about 57-58%. after that, I put a boveda pack in the jar to get it back up tp 62% for my personal perfect smoke (I roll my joint with a cannabis/tobacco mix and use long papers not little ones for cigarettes)
the cure give the buds a smooth taste and its different to keep them at 62% and smoke or to cure let the nugs get drier and rehydrate... my personal experience
ps: I let my plants dry as a whole... if you have a special room for drying, you may be able to cure it as a complete plant, without cutting it apart!!
great stuff!
but I never had the place dedicated for drying only, so I will cut fan leaves as soon as they have shriveld up a bit. but not all of them. some are good to protect your buds
when the plant/ buds are dry to the touch... I talk about some of the lower buds... they tend to be best for checking that (the plant will evenly distribute the moisture), because I dont like to press my good buds to know how much water is inside...
then I trim and jar! I also jar trim with lots of resin for hash... cured trim is always better. but you can paperbag the trim too, just dont let it get to dry before processing/ or use ice water technique
