Well you cure your weed it allows the moisture still left in the stem to absorb into the nuggets, it also allows for chlorophyll breakdown to allow for a better taste, to much chlorophyll makes a hay, fresh cut grass taste. If your buds are to dry you could add some lettuce or something in the jar but this doesnt really consist of curing more like rehydration. Usually if your bud taste hayish once dried it could take up to 6 weeks of a cure to get a more desired taste.
