Just make sure you break up thick colas to prevent bud rot. I usually dry my weed after manicuring it down to nuggets, trying to keep from having large chunks of cola that never completely dries. Part of the curing process is starting with those evenly dried nuggets. And maybe you need to burp them longer to make sure they are not to moist in the jars. Also, I don't know about your harvest, but if you harvest when there isn't enough trich production or if your strain doesn't produce many trichs then you will have a more grassy smell. From my experience, the really dank shit never smelled bad throughout the dry/cure process. Good luck, and congrats on the harvest.
