You need to figure out what the RH is in an empty jar first. If you're working with an RH of 64% in an empty jar I would be content with an RH of 67% in a jar of buds.
As far as how to get to that RH you can read the post I made a yesterday about drying. Basically I go between a jar and bin at 12 hrs a pop in each. So to answer your question about getting to the proper RH that's how I do it.
Once you get a jar of buds to read an RH of under 68% you can put the buds away for a four to six week time period in a large mason jar. After 4 to 6 weeks transfer the buds to smaller jars. That gives everything a quick breather. At that point you can put the smaller jars away for another 4 weeks. At that point give all jars a quick sniff and breather to make sure everything smells good. Now you can put the small jar away for a long time. Hope this helps.
Side note: a lot of people may respond saying a lower RH would be better for putting away for a cure. People seem to like the 55-65 range in print. I however have found it hard to get things down this low since I have been working with mason jars with baseline RH's in the low 60's. At a RH of 67% in a jar the buds are dry. In fact, if I didn't have a hygrometer I'm sure I would think the RH of the buds was much lower.
