How to Choose the Right Micron Bags for Bubble Hash

Choosing bubble bags is easier when you know what each micron size is meant to separate. A smaller micron number means a finer screen. Used together, bags with different screen sizes let you collect material in separate ranges rather than combining everything in one bag.

This guide explains the common micron stages, why people pay particular attention to the 90–120 micron range, and how to choose between a simpler 4-bag setup and more detailed 8-bag sorting.

What does a micron rating mean?

A micron is a unit of measurement. On a bubble bag, the rating describes the size of the openings in its screen. Larger openings let smaller particles pass through while holding back larger material. Finer screens catch material that passed through the bags above them.

A micron number alone does not determine quality. What you collect in each bag can vary with the starting material and how it is handled, so keeping ranges separate gives you a better way to compare them.

What do the different micron ranges do?

The stages in a multi-bag setup serve different purposes:

• Larger screens, such as 220 and 160 microns: Help separate out larger plant material before it reaches finer screens.
• 120 and 90 microns: Keep these commonly discussed collection ranges separate so you can assess each one.
• 73 and 45 microns: Collect smaller material that passes through the wider screens.
• 25 microns: Catches some of the finest material to pass through the other bags.

The 90–120 micron range gets plenty of attention, but there is no universally “best” bag. Keeping those stages separate can help you see what your particular starting material produces instead of relying on a single rule of thumb.

4-bag or 8-bag set: which should you choose?

A 4-bag set is a practical choice if you want fewer stages to manage, rinse, and assess. You still separate material by screen size, but you combine more of the material that a larger set would collect in individual bags. If simplicity matters most, explore the 5 Gallon ‘Original’ 4 Bag Set.

An 8-bag set gives you more separation points. That can be useful when you want to compare narrower micron ranges, including 90 and 120 microns, without grouping as much material together. If detailed sorting is your priority, see the 5 Gallon ‘Original’ 8 Bag Set.

Neither set guarantees a particular quality or yield. The choice is mainly about how much detail you want from your sorting process and how many bags you want to handle afterward.

Does dry ice or ice water change the choice?

Your method may affect how you prefer to work, but it does not turn one micron size into a guaranteed quality grade. With either dry ice or ice water, consider how much separation you want and whether you have time to keep each collected range distinct. Check the product instructions for method-specific guidance before using your bags.

How should you care for your bags?

Rinse the screens after use so material does not sit in the mesh. Handle the screen panels gently, let the bags dry fully, and check for wear before using them again. Follow the care instructions supplied with your set, particularly before using any cleaning product.

The short answer

Choose a 4-bag set if you want a more straightforward workflow with fewer collection stages. Choose an 8-bag set if comparing narrower micron ranges is important to you. Pay attention to the material you collect in each bag, especially around 90 and 120 microns, but let your own results guide your preferences rather than treating any one number as a promise.
