The afgans have been making hash for a long long time. They use a screen over a bowl and a bag over that with the plant materal under the second bag on top of the screen. The wrap it all real tight and then the beat the bag with sticks to know off the crystals. What I want to know is does the plant material have to be dry? I have heard that if you freeze the leaves the crystals will become brittle and break off easy but can you just skip the drying before you freeze and then bang them or should they be dry the frozen.. If you don't know please don't give an opinion. Thanks....
