The plants which are used for Hash production are very small and bushy Indicas. In Afghanistan Hashish is pressed by hand after the addition of a small quantity of tea or water. The Hashish is worked on until it becomes highly elastic and has a strong aromatic smell. In Afghanistan, the Rolling Stones Gold Seal Afghani Hash is stored in the form of Hash-Balls (because a round ball has the least contact with air), however, before being shipped, the Hash is pressed tightly in 100g slabs generally. Good qualities of Afghani are signed with the stem of the producing family.
