no some people air dry for up to a couple weeks... it depends on your climate and stuff too.
even if the exterior layer of bud gets a bit dry, it doesnst really matter because once you put it in the jars, the moisture will even out.
If its still too dry after you cure, you can add a fresh leaf or orange peel in there just to add a bit of moisture.
good luck =)

edit: btw airdrying for 3 days isnt nearly enough in my opinion - I always airdry for at least 6-7 days.
bluntwiz Reviewed by bluntwiz on . Best way to cure when away from bud? I'm going to be out of the country in december for 8 days. I was going to harvest 9 days before the trip and air dry for 36 hours, then put in jars and open every 8 hours for the next 3 days and then every 12 hours for the rest. Optimally, i would like to harvest a couple days before the trip, meaning i could have another week of veg growth. Is there a way to cure the bud while being away? If not, will the buds be dry enough with my previously described method to be left alone for 8 days Rating: 5
