Hello,
For drying you'll want to let them hang anywhere from 3 days to a week depending on how dense they are. When a small bud snaps off versus peels away some of the stem, they're ready to trim, but don't wait until they're so dry they crumble.
You can dip into harvest whenever you need or want to but a cure is best.
If you can keep the jars around 50% that's good and then open them everyday shake and let them breathe for 10-15 minutes. Some people cure for a week and some go for months, the idea is they get better with time, so the longer you let them go the better, but honestly if you got 1-2 weeks in and need to smoke it, it'll be more than ready and yummy.
You can get some tiny temp/humidity gauges on Amazon for cheap that fit in the jars and those can be very handy. Otherwise those Boveda or integra humidity packs are nice too because they're 2 wat humidity control that brings it up to 60% or down to 60% depending on what state the buds are in.
Happy smoking. ✌️
