what screen or mesh size to use for kief collection? FC

Aug 02, 2010 "When making hashish, you can vary the mesh size from about 65-125 microns (about 120-230 lines per inch). If the particles are larger than 125 microns, they are not very potent. As the particle size decreases down to 125 microns, the potency increases. At about 125 microns, the powder is what most people would consider good hash.

Mesh (scale) Wikipedia

Mesh is a measurement of particle size often used in determining the particle-size distribution of a granular material.For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.
