I just finished my first batch following directions that mixed 1lb of dry ice into 7lb+- ice with previously cured/dried then frozen flower (put flower in a plastic bag, push as much air out as pos. & seal/freeze. A vacuum bag is even better to keep the water out) Frozen bud is broken up by pounding by hand and added to the ice mix into the work bag. Screens have been stacked into 5gal. can in order, finest first. Directions said to shake after a while. Upon lifting the can with my arthritic body, I imagined that my 12" orbital polisher might be used as a super "paint shaker". So I straddled the bucket between my legs while sitting on my drum throne (adjustable height important for leverage and stability) centered it onto the polisher, turned it on and held on for dear life! Just 2-3 min. of this was a great massage for me and I imagined the best way to separate tricomes from plant matter using what I already had! Yield was not impressive but what the heck I have to use up the leftovers from the 18 harvest to make room for the upcoming. I just combined the results from the three finest screens (5 bag set) to get the pictured results. Smooth and tasteful smoke as a bowl topper, it's Way superior to the Slugg 33 press I bought and a great way to get Something from all this without the cost of alcohol or elaborate equipment. I'm hoping further experience and any tutoring will help me get a better yield. (this is from 2oz's white widow)
