Gramse...that question requires a big answer. It's probably best to mention what your end goal is. Do you want quality over quantity with 90+% resin purity or do you want as much good quality dry sifted resin as possible from the plant material you have to work with? Describe your plant material too.
and it might be a good idea to use the ICmag search feature and so some reading, there's some great dry sifting here. A couple of hours reading here per day for a week or two and you will well versed how to dry sift in several ways. This site has, by far, the best dry sifting information on the web. The first innovators of static sifting, rosin with a bowl and recently the hair straightener method , the gentle two screen method and other methods and improvements were all posted here first...and have made very pure dry sifted resin is reality for everyone. Static sifting is used after the material has been tumble or flat screen sifted to remove the resin heads from the contaminated dry sift... and the two screen method separates the resin at the beginning
Happy Sifting
I have to ask you, how do YOU preparing the material before you sift it? Only dry it or do you also freeze it?
