Micron screen

Micron screens are fine metal mesh filters used by hash makers to separate and collect purified trichome resin heads when creating solventless hash products like kief, bubble hash or dry sift. Plant material containing trichome-rich cannabis flowers or trim gets systematically sifted through a series of stacked screens with progressively smaller micron sizes. Ideal hash comes from selectively filtering out fully mature, intact trichome heads bursting with cannabinoids and terpenes while excluding contaminants. Larger mesh openings allow more undesirables like stalks, stems and leaf particles to pass through. Using multiple screens of descending micron sizes refines the end product into higher quality. Generally, the smaller the micron, the higher potential potency, but yields drop as mesh gets super fine. Finding the ideal balance requires experimentation and precision. Micron screens empower artisanal hash makers to dial in the perfect texture and purity.
