Rosin 70u is a premium solventless cannabis concentrate made from trichome heads filtered through a 70-micron wash bag. The “70u” label means only trichomes measuring 70 micrometers were collected, capturing a pure, flavorful, and potent mix of resin glands ideal for dabbing.
What 70u Means
- Micron Size: Refers to the filter mesh size used during ice-water hash extraction to isolate specific trichome head sizes.
- The “Golden Zone”: A 70u sizing is often prized as a sweet spot for full-melt hash or live rosin, balancing high purity with deep terpene flavor.
- Single vs. Mixed Spectrum: While some extractors use a full spectrum (e.g., 70u–159u), a dedicated 70u wash isolates a tighter, high-grade tier of the plant’s resin.
Key Characteristics
- Extraction: Made using only ice, water, heat, and pressure—no chemical solvents.
- Consistency: Often found as a cold-cure badder, wet sauce, or full-melt hash.
- Profile: Delivers a cleaner, more true-to-plant taste and strong potency compared to standard flower rosin.
