Rosin labels with numbers like 90u or 120u can easily confuse even experienced Washington dab shoppers. These numbers do not represent quality scores or THC percentages—they actually refer to the micron size used to filter trichomes and plant material during solventless extraction. For those shopping in Washington, understanding what 90u and 120u mean helps you select the concentrate that best matches your desired purity, flavor, and consistency. At Floyd’s Cannabis, we help our customers decode these details for a better shopping experience—and to ensure you always get fact-based, compliant guidance at any of our locations statewide.
What Do 90u and 120u Microns Mean in Rosin?
The terms 90u and 120u indicate the micron size (measured in micrometers) of the filter screen or bag used to separate trichome heads from cannabis plant material during hash and rosin production. “U” stands for micron, a scientific unit equal to one-millionth of a meter. In solventless extraction, smaller micron numbers like 90u create a finer filter, while larger numbers like 120u capture slightly bigger trichome heads and sometimes more plant particles.
For Washington shoppers, these details matter because:
- 90u (90 micron): Often regarded as the “sweet spot” for mature trichome heads prized for flavor, aroma, and visual clarity. Many producers select 90u as a top-tier rosin grade for its clean melt and strain expression.
- 120u (120 micron): Sits above 90u on the size scale and can yield more product with potentially slightly more plant material. Still, many high-quality rosins are pressed from this range, sometimes with a more robust texture or broader flavor.
Ultimately, the micron range gives you insight into concentrate style and how the product was crafted. But it is just one variable—batch technique, source flower, and storage all impact the final result.
90u vs 120u: What Each Micron Range Means for Dab Shoppers
Rosin makers and educated shoppers throughout Washington often highlight specific differences between 90u and 120u. Here’s how each typically compares:
- Flavor and Aroma: 90u rosin is associated with bright, strain-forward flavors and highly aromatic profiles. The smaller filter captures mostly intact trichome heads with minimal wax or leaf, helping preserve volatile terpenes.
- Visual and Texture: 90u usually produces lighter, more translucent rosin. 120u may be slightly darker and can vary more in texture, ranging from creamy to more granular, based on extraction technique and cannabis genetics.
- Yield: 120u can increase overall yield because the bigger filter catches additional trichome material. This can be appealing for shoppers looking for both quality and quantity at a good value.
Neither micron is “better” by default. Instead, many shoppers use both as data points when comparing rosin options at a Washington dispensary. At Floyd’s Cannabis, our knowledgeable team can help you interpret these details in real time, letting you find a product that fits your taste, budget, and experience level.

How to Read Rosin Labels and Shop with Confidence
At Washington dispensaries like Floyd’s Cannabis, labels play a crucial role in helping shoppers make informed choices. Here’s how to get the most out of your shopping experience:
- Check the Micron Range: See if the product is single-micron (90u or 120u) or mixed-micron (sometimes called full-spectrum or blend). Both offer unique expressions; single-micron leans toward purity, while blends emphasize a broader snapshot of the harvest.
- Review Cannabinoids: Potency is listed in percentages for THC, CBD, and sometimes CBG or other minors. These always reflect the specific batch on shelf and must be lab tested per Washington State regulations.
- Terpene Profiles: Some brands provide real terpene breakdowns, listing dominant terpenes that influence aroma and flavor. While not every label will include this, you can always ask staff or review shop descriptions when available.
- Source Material: Labels may include details like “fresh frozen” or “cured,” which references how the cannabis was prepared before extraction and can affect taste, consistency, and finished yield.

Best Practices for Shopping 90u and 120u Rosin in Washington
Whether you favor 90u or 120u, here are simple strategies to get the most out of your solventless purchase at Floyd’s Cannabis:
- Compare Micron Alongside Strain and Terpene Profile: Focus on all the label details together. A 120u batch of a high-terpene strain could be as pleasing as a 90u from another cultivar when fresh and well-stored.
- Ask About Single-Source and Mixed-Micron: For deeper quality, many consumers ask if the rosin is from a single harvest or a blend of sources, or whether it was pressed for maximum purity or higher yield.
- Store Your Rosin Properly: To preserve aroma, color, and consistency, keep solventless products sealed and cold, especially if you buy more than one gram at a time.
- Understand the Dab Experience: While many shoppers report clearer flavor and a smoother consumption experience with solventless products, results vary by batch and personal preference. Product selection advice from staff at Floyd’s Cannabis is always educational, not prescriptive.

FAQ: 90u vs 120u Rosin for Washington Dab Shoppers
What does the “u” in 90u or 120u rosin stand for?
The “u” means micron, which is a metric unit of measurement used for filter sizes in extraction. It determines the fineness of material captured from the starting cannabis during solventless processing.
Does 90u always mean higher quality than 120u?
Not always. Many solventless fans consider 90u a “sweet spot” for purity, but excellent 120u rosins exist. Overall quality depends on grower technique, starting material, and pressing standards—label details should always be weighed together.
What kind of effects should I expect from solventless rosin concentrates?
Effects can vary by strain, cannabinoid percentage, and your own biology. Products are labeled with common cannabinoid and terpene data as available, and staff can share non-clinical insights about typical consumer experiences—but no effects are guaranteed.
How do I pick between single-micron and mixed-micron rosins?
Single-micron rosin (like 90u or 120u alone) is often chosen for its selectivity and clarity, while mixed-micron batches may offer more complete representation of the plant and slightly higher yields. Compare both style and label info when choosing.
Where can I shop current solventless rosin inventory in Washington?
You can browse concentrates—including solventless and rosin options—at Floyd’s Cannabis in Burlington, Mount Vernon, Port Angeles, Pullman, and Sedro-Woolley. Online menus let you filter by product type, strain, or cannabinoid content before you pick up in-store.
