A good rule of thumb I read somewhere for when to stop hang drying and start sweating in jars is if you squish a bud and it stays squished it’s still too wet, if it crumbles its too dry (duh lol), if it sort of sponges back to shape it’s right in the zone.
I’ve been using this for a while now and it works great for me. I find they’re just before the stem snapping point when I jar them and then get there with sweating/breathing over the next few days.
