stick them in a air tight jar and check the jar every day. it should pull some moisture out of the middle and make the rest of the buds moisten back up. if they don't moisten up after a couple days you can put a piece of lettuce, orange peel, or whatever else you can think of to moisten it back up. but remember to check the buds after a day, because a little moisture goes a long way and you don't want your smoke getting moldy.
