mix ice water and trim for 10 min, poor into the 200 micron which is sitting on top of the 75 micron with another 5 gallons bucket to collect water. 200 micron is only used to remove most green matters and goodies are in the 75. I do the gravity method with the filtered water to collect all trichomes that are smaller than 75 microns. look gumbo bubble hash on youtube ... good luck! Once you finish the first time you can add water to trim and ice and repeat and the quality goes down but still extracting resin heads.
