Get a herb grinder with screened pollen catcher, once you have accumalated enough pollen ( trichs ) get a pollen press and make hash. or dry your trimmings and place in a mason jar with ice cold water, and some ice shake the hell out of it, place in fridge for a few hrs, skim out the floating trimmings carefully, poor the remainder through a coffe filter, let dry, scrap up the hash and put in a pollen press.
