Hash is just pressed kief but you must start with a high grade kief. The Kief can be not as good, as good or better than hash depending on the screen size used to collect it. If it forms a ball that doesnt crumble when pressed, the oil content is high and its good. This ball is hash. BUT most keif (like the stuff in your grinder) has too much plant matter to compress naturally. Its got tons of trichs but also some plant matter (way less than bud but a little more than hash)
