Bubble Hash Micron Bags Explained: Which Sizes Do You Really Need?

ByJay

If you’re new to making bubble hash, the world of micron bags can feel overwhelming. Do you really need a full set? Which sizes give you the best hash? And what’s the difference between 220µ and 45µ anyway?

At Aether Green, we designed our Automated Hash Washer to work seamlessly with a complete bag setup — because using the right bags makes the difference between average hash and melt-worthy resin.

Here’s a breakdown of what each size does and how to choose the right set for your needs, particularly focusing on micron bags efficiency.

What Are Micron Bags?

Micron bags (also called bubble bags) are fine mesh filters measured in microns (µ). One micron is one-millionth of a meter — so the smaller the number, the finer the mesh.

When making bubble hash, you line your collection bucket with multiple micron bags stacked inside each other. As trichomes separate from the plant, they filter through the layers, getting caught at different sizes, demonstrating the subtlety of using these specialized bags.

👉 Think of it like a coffee filter system: each bag lets smaller particles pass while holding back larger ones.

Common Micron Sizes and What They Collect

Here’s what each bag typically does:

  • 220µ (Work Bag):
    Catches large plant debris. Not meant for smoking — this bag keeps your other layers clean with the help of micron technology.
  • 160µ:
    Collects larger trichome heads and contaminants. Some usable resin, but often lower grade, vividly showing the micron bags’ purpose.
  • 120µ:
    High-quality trichomes with great melt potential. Often considered one of the “cream” bags.
  • 73µ:
    The gold standard for bubble hash. Captures the perfect size trichome heads for six-star melt.
  • 45µ:
    Smaller resin heads. Still excellent quality, especially for certain strains.
  • 25µ (Optional):
    Collects the tiniest trichomes and dust-like resin. Sometimes flavorful, but often less melty.

Do You Need All the Bags?

Technically, you can make bubble hash with just a few bags (like 220µ, 73µ, and 45µ). But for the best separation and quality control, we recommend a full stack:

  1. 220µ
  2. 160µ
  3. 120µ
  4. 73µ
  5. 45µ

This setup ensures you capture every grade of resin and can separate full melt from food grade hash.

👉 Pro tip: If you’re new, start with at least three bags (220µ, 120µ, 73µ). Add more as you refine your process, especially focusing on varied micron bags.

How to Layer Micron Bags

Always stack bags largest micron on top, smallest on the bottom inside your collection bucket. That way, resin filters down layer by layer until it’s fully separated.

For example:

  1. Place the 220µ bag in first (this will be the outermost bag).
  2. Next, stack 160µ, 120µ, 73µ, and 45µ in descending order.
  3. Pour your wash water through the stack.
  4. Collect resin from each layer individually.

Which Bags Make the Best Hash?

The 120µ and 73µ bags are where most hashmakers find their top-grade melt. These sizes capture the ripest, most resinous trichome heads, making them critical when using micron bags for quality.

The 45µ bag can also produce excellent full melt depending on the strain. Some genetics drop smaller trichomes that shine at this level.

Meanwhile, the 160µ and 220µ are usually lower quality but can still be pressed into edibles or rosin.

Why Micron Bags Matter More With Automation

When using the Aether Green Automated Washer, consistent agitation means your trichomes are freed cleanly and evenly. Pairing this with the right micron bag set ensures you capture everything without contamination. The combination of automation and the right bags is ideal.

Together, automation and proper filtration give you the purest, most melt-worthy bubble hash possible.

Final Thoughts

Micron bags aren’t just accessories — they’re essential tools for clean solventless extraction. By understanding what each size does, you can dial in your process, improve your yields, and separate true full melt from lower grades.

Pair your micron bags with the Aether Green Automated Hash Washer, and you’ll have a system built for consistent, professional-quality results — right at home.
