Stonerdanswered grow question 4 years ago I'd suggest leave it drying until the last minute then put in jars under cool and dark climate (20-24 degrees Celsius and 50-60% humidity which is usually room climate) and leave it there until you're back. Leaving them to dry for 3 weeks will just turn it bone dry and degraded (although moisture can be retained with few methods, but still not recommended).
Just make sure jars are airtight and you're good👌
Good luck! and happy drying :)
