Those little numbers on a hash jar describe a collection window. They tell you which mesh sizes were used to separate resin—not whether one strain or jar is automatically better than another.

01 / The measurementWhat does
What does
“micron” mean?
A micron (µm) is one-thousandth of a millimeter. In hash making, it measures the openings in a collection screen.
During an ice-water wash, water and separated trichome heads pass through stacked mesh bags. Each bag catches material too large to pass through its openings. A 90µ screen has smaller openings than a 159µ screen.
The number describes the screen—not the potency, aroma, or quality of the finished hash.

For the overall sequence, see Our Process. This guide focuses on the meaning of screen sizes and collection ranges. Our process
A collection range describes the screens selected for a batch. It does not tell you how much of each fraction went into the jar.

Read the range.
These are the collection ranges we use for our live hash rosin tiers. The bars show how broad each window is; they are a visual guide, not a purity or potency scale.

A broader range selected from the first and second washes, with a balance of refinement and body.

04 / Beyond the numberA range is
A range is
not a rating.
More selective does not mean universally better. A wider collection can carry a character of its own.
Start with the plant
Genetics, harvest timing, and the structure of a cultivar’s resin shape what can be collected.
Consider the full run
Wash conditions, drying, selection, pressing, and storage all influence the finished jar.
