Fact Checked by Doctor NameWhat is a Micron Grade?
The micron grade refers to the hole size in filtering screens used to separate trichome resin glands from plant material. This grade correlates to the size of hash or concentrated cannabis created.
Micron sizing provides a scale for classifying extracts based on the trichome heads collected. The ideal spectrum ranges from 25-159 microns.
The smallest glands produce the highest quality solventless hash and concentrates.
Full melt hash tests at 25-45 microns, gathering just the resin heads. This creates smooth, potent products preferred by connoisseurs.
Larger 45-73 micron grades include more stalks and plant waxes for reduced purity but higher yields.
At 70-90 microns, quality drops further with more contaminants. Airy “Bubble hash” tends to test from 75-159 microns.
Kief generally measures from 125-159 microns, containing fine particles and debris along with resin glands.
By considering micron grade, processors optimize extraction methods, and consumers choose products aligned with individual preferences.
The finest, low-micron grades contain primarily capitated stalks and intense cannabinoid and terpene profiles.
