Yes, under “average” conditions, you bag it when they start to loose that moist feeling on the outside, then you can layer gently. The idea is to let it dry slowly over the course of a few days to a week before jars. But if everything tends to dry too quick, that’s when they go straight in the bag, but single layered. Jar when “popcorn dry”, before anything starts to crumble. Check regularly for condensation, use a coffee filter or cheese cloth as a top for the first day or two if necessary. The idea is to “sweat” the material, allowing moisture from inside the bud to evenly move to the outer/drier part. Open the jar for a few minutes to breath daily until everything is evenly dry, check the nugs at the bottom, center, and the top of jar. Then break open a decent sized jug to check the consistency and center of the bud. Test it, (oh so much trouble). It should be moist enough to not crumble when you pinch it, but dry enough to smoke without trouble lighting. Once your satisfied that it’s dried enough, loosely fill various size containers and use as is, or let them age and cure in a cool dark place. Once you start pulling any amount of buds from the jar, or open it too many times, you should consider it your active jar, or transfer it all into a smaller jar with less headspace. Treat it like a bottle of wine or fine liquor.
Only add hydration to stuff your going to be smoking soon. But, If you really over dried your stuff before curing, and feel you absolutely need to rehydrate, one of those humidor hydration/humidity pucks can be used in a larger jar briefly. Some extra air space is your friend in the case. Check regularly and put the buds in smaller jars once your happy with the moisture level, and proceed with burping if needed.
Wow I got wordy. I Figured I’d sum up my process from back in the day. Again, I haven’t done this myself in over a decade, sorry if I sound like I’m repeating the basics.
