73–159µ Micron

what “73–159µ Micron” actually means in the context of THCa rosin:


🔬 What Micron Ratings Mean

  • Micron (µ): A unit of measurement equal to one‑millionth of a meter.
  • In rosin production, micron ratings refer to the size of the mesh openings in the filter bags used during pressing.
  • These bags catch plant material while allowing resinous trichome heads (the good stuff) to pass through.

🌿 73–159µ Micron Range

  • 73µ – 159µ indicates the range of trichome head sizes collected and pressed into rosin.
  • Trichome heads typically fall between 70µ and 160µ, which are considered the “sweet spot” sizes for solventless rosin pressing.
  • This range balances purity and yield:
    • Lower microns (25–45µ): Capture smaller heads, very pure but lower yield.
    • Mid‑range (73–120µ): Considered the headstash zone — best flavor, potency, and terpene expression.
    • Higher microns (149–220µ): Capture larger heads, higher yield but sometimes less refined.

So when you see 73–159µ, it means the rosin was pressed from bubble hash collected in that micron range — essentially the prime trichome heads that deliver both potency and flavor.


⚖️ Why It Matters

  • Quality: Mid‑range microns (73–159µ) are prized for connoisseur‑grade rosin.
  • Flavor: Strong terpene preservation, clean melt.
  • Yield: Good balance — not as low as 25µ, not as “dirty” as 220µ.
  • Marketing: Including the micron range on your product page signals craftsmanship and transparency.
