Overdried marijuana cure?

It's been 4 days since I hung my plants, and they seem to be too dry. The leaves are "chrispy". The humidity in my room is about 30%

Is there a way to fix this?

get them in jars so the moisture inside the middle will even everythig out.

Im afraid you cant "undry" the already dried buds. take a sample bud and slice thru the middle. Is it dry in there too?

Put it in the jar right away with the lid on for atleast overnight ifnot a full day to allow them to sweat a bit then remove the lid for a brief period til they seem to have crisped again then put the lid back on an so on...
