The right micron size for Rosin Bags: A guide from Graveda:
Dear Cannabis Enthusiasts,
The Rosinpress technique has become increasingly popular in the cannabis community. A crucial factor for the success of this method is the choice of the right Rosin Bag. The micron size plays a central role in this. But which size is right for your material? Lets find out!

What does micron size mean?
The micron size of a rosin bag refers to the size of the holes in the sieve of the bag. A micron is one thousandth of a millimetre, i.e. extremely small. The smaller the micron size, the finer the sieve and theoretically the purer the rosin concentrate. Why theoretically? Cannabis is a natural product and flower A behaves differently to flower B. Furthermore, flower A can also produce a different result on other days due to storage and changes in humidity, for example. Since cannabis is a natural product, such differences can be noticeable ;-)

Which micron size for which material?
5 micron:
Optimal for: Mechanical separation of waxes from terpenes.
Why? These ultra-fine sieves allow a very specific separation, ideal for advanced extraction processes.
15 micron:
Optimal for: Production of THC-A.
Why? This size is specially optimised for filtration in THC-A production.
25-35 micron:
Optimal for: Finest materials such as bubble hash or dry sift.
Why. These fine sieves prevent small particles from passing through the sieve and mixing with the rosin.
72-90 micron:
Optimal for: General hash extractions and high quality flower.
Why. These sizes provide a good balance between flow and filtration, resulting in a clean cannabis concentrate.
120-160 micron:
Optimal for: fresh cannabis flowers and optimal yield.

Why?
When processing flowers, fine particles are less likely to pass through the sieve. A coarser screen allows for better flow and yield.
Tips for choosing the right Rosin Bag:

Material quality:
The higher quality and cleaner your source material, the finer the micron size can be. For dry material, a 90 micron bag is better than a 120 micron bag.

Yield vs. purity:
A finer screen may result in a cleaner rosin, but possibly at the expense of yield. A coarser sieve can increase the flow, but there is a risk that more unwanted particles will pass through.
However, the particles are often not visible even with a microscope. Every Friday we do a live stream on YouTube and Twitch and try out these things live with you. Afterwards, most of the live streams are still online on Graveda (YouTube).

Experimentation:
Everyone has different preferences and goals. It can be helpful to experiment with different micron sizes to find out which works best for you and your material.
