I notice a similar effect with my stash jars. They have very little aroma. Even breaking open a bud smells only moderately. But if I leave a bud out to breathe for a while, it smells up the room.

Has anyone else experienced this, or do I sound as crazy as I fear I might?
I know exactly what you mean. In a sense, it can be compared to aerating a red wine or a younger white. Once the wine is uncorked and allowed to mix with air, the interaction can bring out a more complex and noticeable fragrance. In my own situation, if I want to really impress with the smell of my product, I fill a big jar ~1/2 full for a few days (after the flowers are well-cured).
