I was wondering if you guys could help me clarify a few things. I've seen people talk about using unbleached coffee filters for the bottom. My particular extraction tube is from extraction experts and they give you 2 50U Micron screens. I was wondering if anyone has had experience with these and if they work well? (Im worried about having a blowout, since Im doing an ounce for my first time). The majority of the nugs are fairly dense and large, but I plan to have them down to dime and nickel size nugs when I pack them. (I have heard that whole nugs gives a purer yield, and ground up bud can lead to possible chlorophyll contamination). I was also wondering what preference you guys have on the way you purge your product or how you make different types like amber glass, wax, honeycomb, etc? Any feedback on this would be great. Thanks.
