I highly recommend a quality Hygrometer in at least 1 or 2 of your jars (if you have multiple)
If the RH gets above 70%, take it back out and either paper bag / screen for a few hours, then back in the jars.
I used Hicks "cure by numbers" bit, and the best thing I learned out of that was RH ranges and buying a quality Hygrometer (not those cheap-o's that can float 5% and higher RH difference)
Especially want a hygrometer if you've not waited long enough. Your buds should have a crisp type of sound when you squeeze them.. also when you squeeze them, they should "bounce back" like a piece of memory foam. Also, when you try to snap the stem you start to hear / feel the potential of snapping, without actually clear off snapping. That will be too long of a dry, and you don't take advantage of the entire cure window, which is 70% - 55%. After you drop below 55%, the cure is over... if you get even 1% higher than 70% you really risk mold issues.
Here's a pic of a jar that was 1/2 full, and I put a Hygrometer in. I use the Caliber IV meter, as it's pretty much the best you can get. I got mine for $18 each, and I bought 4 of them.
