It depends on how you like the cure. I prefer RH about 58%. It is easier to jar them higher than that, then remove them for further air drying until the RH is where I like it, than it is to try and rehydrate them. I recommend using some small digital hygrometers in at least some of the jars to monitor RH. After the desired RH is achieved, I air them out enough to exchange the air in the jar, about 10 minutes. It also will depend on what the ambient RH is. Once the desired RH is achieved and or several weeks have passed, shorter times are sufficient.
