90u vs 120u Rosin Bags for Flower: Clarity vs Maximum Yield Compared

90 micron (90u) nylon bags are the all-purpose gold standard for cured craft flower (62% RH), filtering out fine bract dust while yielding 18% to 24%, whereas 120 micron (120u) bags maximize total flower yield (21% to 28%) on fresh, sticky harvest buds.

Interactive Rosin Platen & Bag Footprint PSI Calculator

Calculate both Platen-Level PSI and True Bag-Level PSI. Hydraulic gauge pressure is NOT bag PSI: a 10-ton press on a 2x4 inch bag delivers 2,500 PSI at the mesh, which will cause an instant blowout unless throttled.
