Moroccan style is pretty sweet and easy, 120 is a little small good for a second sieving if the first with 190 or 160 is not good enough. I personally use 190 and sieve the resin collected a second time with a 160 microns
I never use a 220 micron to dry sieve I prefer 190 micron screen but you are right the dry sieve Moroccan style was done with a 220 bag and it is better than nothing. If you cam have a 160 or 120 to refine through a second sieve you would have pretty clean resin which however doesnt mean quality
You have to understand that I collect trichomes like I would collect ripe fruits from a tree since trichomes are made like a fruit with an abscission under the heads so that they fall when mature and ripe. My first wash is a light shake so that the ripest fruits fall, my second wash is slightly...
You saw Nepalese producing export Charas/Hash but you have not seen a Nepalese make Royal Nepalese Temple Balls if you are my age or younger, I will turn 60 in December and Royal Nepalese Temple Ball were already a myth when I was in Nepal in 1980.
