Who the FUCK have you heard that from? That are possibly the most stupid thing i have heard. Plants start to get their smell when they have a few sets of serrated leaves, and when they bud the smell goes through the roof. If your growing more than one id get a carbon scruber to get rid of the smell. A plant cant just randomly get a smell from being dryed. And yes, the plant will have a more pungent bud smell once its been cured for at least 3 -4 weeks.
