What Exactly Is a Micron Size?
To start, a micron (µm) is simply a unit of measurement representing the size of the openings in your rosin bags. One micron equals one-millionth of a meter. Lower micron numbers mean smaller holes, which filter out more impurities. Conversely, larger micron numbers indicate larger openings, allowing more material through, often increasing yield but sometimes at the cost of purity.
Understanding micron ratings enables you to fine-tune your hash rosin, depending on whether you're aiming for maximum clarity, flavor, or simply more yield.
Top Micron Sizes for Hash Rosin and Their Uses
The four most common micron sizes for hash rosin bags are 36µm, 72µm, 90µm, and 115µm. Let's break down how each performs in detail.
36 Micron Bags – For Maximum Purity
A 36µm rosin bag has extremely fine filtration, making it perfect for pressing bubble hash or dry sift (kief). These smaller holes prevent plant material and impurities from contaminating your rosin, resulting in the cleanest, clearest rosin possible.
The downside? Slightly lower yields. Since fewer impurities pass through, you'll naturally collect a bit less rosin. However, this is the choice of connoisseurs and award-winning extractors, as the purity achieved here is unmatched.
72 Micron Bags – Balancing Yield and Quality
A 72µm bag is the sweet spot for hash rosin enthusiasts who want great clarity without sacrificing much yield. It filters most impurities yet still allows sufficient material through to deliver solid yields, maintaining exceptional flavor and potency.
The 72µm bag is particularly suited for pressing high-quality bubble hash, offering excellent results that often rival smaller micron bags in clarity and flavor, with the added benefit of a better yield.
90 Micron Bags – Great for General Use
The 90µm rosin bag is popular among producers pressing quality bubble hash and kief. It provides a slightly higher yield than 72µm bags, albeit with a minor reduction in clarity. Yet, for most hash rosin producers, this trade-off is minimal, making 90µm an excellent choice for consistent quality across various hash grades.
115 Micron Bags – For High Yield Extraction
If maximizing yield is your primary goal, the 115µm rosin bag is ideal. It offers larger openings that allow more rosin to flow through easily. However, the compromise here is that you'll typically see more impurities and slightly lower clarity compared to finer micron sizes.
Producers opting for bulk production, or those less concerned about achieving pristine clarity, will find the 115µm bags practical and efficient.
Expert Recommendations: What Micron Do Professionals Prefer?
Most professionals aiming for competition-grade hash rosin recommend using a 36µm or 72µm rosin bag. The smaller micron sizes significantly boost quality, making the rosin cleaner, clearer, and more terpene-rich.
Bud Smith, an award-winning rosin extractor, explicitly prefers the 36µm bags, noting that although yields slightly dip, the superior quality and clarity far outweigh the minor yield loss. This sentiment is echoed widely among expert extractors, who prioritize the purity and flavor profile of their rosin above everything else.
How to Choose the Best Micron Size for Your Needs
Your choice ultimately boils down to your specific goals:
- Maximum Clarity & Purity: Opt for 36µm.
- Balanced Quality and Yield: The 72µm is your perfect midpoint.
- Versatile General Use: 90µm offers versatility and consistent results.
- Highest Possible Yield: Choose the 115µm bag for bulk pressing.
Consider also the quality of your starting material. Premium bubble hash and kief are ideally pressed at lower microns, while more standard or lower-grade material benefits from slightly higher microns.
Additional Tips for Optimizing Hash Rosin Extraction
Beyond selecting the right micron size, you can further optimize your rosin extraction with these tips:
1. Temperature Control
Low-temperature pressing (between 150°F and 190°F) preserves terpenes, enhancing flavor and potency.
2. Pressure Management
Apply consistent pressure gradually; sudden pressure can burst bags or degrade your rosin quality.
3. Quality Material
Use freshly frozen or high-quality bubble hash for noticeably better results.
Wrapping It Up: Achieving Perfect Hash Rosin
Selecting the best micron size for hash rosin involves understanding the relationship between clarity, yield, and your specific extraction goals.
Remember, lower micron sizes provide exceptional purity, while higher microns boost yield. For the best overall results, the industry consensus is to lean toward smaller microns, such as 36µm and 72µm, especially for premium-quality hash rosin.
By making an informed micron selection, you’ll consistently produce hash rosin that meets—and surpasses—your quality expectations, delighting users and setting a high standard in the industry.
With the right micron choice, outstanding hash rosin isn’t just achievable—it's guaranteed.
Frequently Asked Questions About the Best Micron Size for Hash Rosin
- ◄What is micron size in hash rosin bags?
- Micron size refers to the size of the openings in rosin filter bags, measured in microns (µm). Smaller micron numbers mean finer filtration, while larger ones allow more material through.
- ◄How does micron size affect the quality of hash rosin?
- Smaller micron sizes filter out more impurities, producing cleaner, purer rosin with better clarity and flavor but usually lower yield. Larger micron sizes increase yield but may reduce purity and clarity.
- ◄Which micron size is best for maximum purity?
- 36 micron bags offer the finest filtration, ideal for producing the cleanest and most terpene-rich hash rosin, especially when pressing bubble hash or dry sift.
- ◄What micron size balances yield and quality?
- 72 micron bags provide an excellent balance between yield and quality, filtering most impurities while allowing good rosin flow.
- ◄Are 90 micron bags suitable for general use?
- Yes, 90 micron bags are versatile, offering consistent yields and clarity, making them popular for pressing various grades of bubble hash and kief.
- ◄When should I use 115 micron bags?
- 115 micron bags are best for maximizing yield, allowing more material through but often resulting in lower clarity and more impurities in the final rosin.
- ◄What micron sizes do experts recommend?
- Most professionals prefer 36µm or 72µm bags to produce competition-grade hash rosin, prioritizing purity, terpene preservation, and clarity.
- ◄How does the quality of starting material influence micron size choice?
- High-quality bubble hash or kief is best pressed with smaller micron bags for cleaner results, while lower-grade material benefits from larger micron bags to improve yield.
- ◄What role does temperature play in hash rosin extraction?
- Pressing at low temperatures (150°F–190°F) helps preserve terpenes and enhances flavor and potency in the final rosin product.
- ◄How can pressure affect hash rosin quality?
