dont do hash. for some reason its a little harder for the trichs to separate from the stems (i've tried this a few times). i would make butter. just grind them up as much as possible and put them in a crock pot with a stick or 2 of butter and 2 cups water. let them cook on high for 2 hours and low for another 2 hours. pour it into a cup and put in th fridge or freezer to cool down and separate the water from the butter. pull the butter out and BAM! u got some potent ass weed butter. by the way how many stems do u have? the smaller the stem the better.
