i think the biggest reason for no smell after harvest is just picking too early, most of the terps get made in the last week or two, if you pick a week or two early, you then have only a small fraction of the terps in your buds that you should have when your buds are dry, and no amount of curing will change that.
another factor i think is the strains that are generally thought of as fast or high yielding already lack in the smell department. if you early pick a strain like northern lights or c99 you end up with a bag of grass no matter what...conversely i think most people know that og or chemdog take 11 to 12 weeks for ripeness, so people are picking them more on time than say northern lights wich most people pick way too early...not to mention chemdog and og kush have redonkulous stanks to them, and og kush especially, gets its smell early on, while chemdog seems to hit later before it's ripe.
i would advise to just go a week or two longer before harvest next time, you will end up with smellier, tastier buds guaranteed.
