Yes, the smell will return. But a lot of it will also have to do with whether or not you flushed your plants properly. Plants can smell dank whether they are full of nutrients or not while fresh, but it's another story as they start to dry. What you could be experiencing now is smelling them sweat out a nutrient concentrated moisture. If you DID flush properly, then this could just be normal and yes, it's natural odor & aroma will return. How well you go about this process will also determine to what degree it comes back. As iampolluted said, you don't want to let them dry out TOO MUCH before jarring, otherwise it will turn out to be very brittle, less fragrent cannabis. I aim for 3, maybe 4 days of hang drying before I start to trim. And at this point, a lot of the time they will still have a lil longer to go. It's just a good time to handle and start working on all that. As the trimming process can delay you from jarring on time if you don't do it all in a proper timeframe. As I trim the buds, they will go into a bowl or some brown paper bags for another couple days, and I will gently mix them around to make sure there's no moisture buildup as they continue to dry. After this point, they are about ready for jarring. I lightly fill each jar so there's plenty of room for them to breathe & sweat without causing mold risks. Then on a daily basis, I will "burp" the lids as some like to call it, leaking air for atleast an hour and then sealing again. Prob best to do this 2-3 times a day the first couple days, then once for the next week before you really start to notice it is approaching a quality cure. From there, the longer you cure the more vintage it gets. I've gone into my golf bag before and found chocholate raspberry, sour diesel, ... in the past that had to of been over 6 months old and while the cannabinoids can degrade slightly, I remember still getting blazed and the taste was incredible and better than ever.
Hope this helps! +rep??? =)
