8 days really means nothing if the drying conditions aren't right. The stems of the buds should crack when you bend em before they go in the jar and the buds should feel stiff/ borderline crunchy. Once dried properly and in jars, just give em a good tumble in the jar, then crack it open to burp every day for a few days to a week. If they dont tumble loose in the jar, they are likely still too wet for jars. I've grown some pretty sticky bud and it always tumbles loose in the jars when dry. If you try to jar up weed thats still too moist you're likely to get damp hay smells and mold.
