The practice of separating bubble hash through multiple mesh screens of decreasing micron sizes (e.g., 120, 90, 73, 45 micron) to isolate trichome heads by size, then evaluating each micron fraction independently for quality.
// From the Episode
Colin Palmer emphasized that his team 'lives by those bags' and grades each micron fraction before deciding what qualifies as top quality, noting that 120 micron can be fantastic in certain varietals while 90 is better in others. Nikiti and Jenn Doe both noted that cutting corners by removing bags (skipping micron grades) and mixing microns together is a common shortcut that degrades quality. Jenn argued the freeze dryer masked this corner-cutting by producing uniformly light-colored hash regardless of cleanliness.
