Which Micron Bag To Use?

Depending on your material, the proper micron bags are suggested but results will always vary.

For kief, dry sift, hash, and bubble hash, use a 36 micron or 72 micron bag. 

72 micron rosin bags will offer higher yields compared to 36 micron rosin bags, but the 36 micron bags will provide the highest quality product.

For flower, trim, and shake, use a 115 micron or 90 micron bag. 

You will get the highest yield from a 115 micron rosin bag compared with a 90 micron rosin bag, but the 90 micron bags will give you more filtration and slightly higher quality product. 

36 micron - Most filtration available, highest quality output rosin for use with kief, dry sift, hash, and bubble hash

72 micron - High level of filtration, increased yields over 36 micron when pressing kief, dry sift, hash, and bubble hash

90 micron - Higher level of filtration for use with flower, trim, and shake rosin pressing

115 micron - Ideal level of filtration and high yielding for use with flower, trim, and shake rosin pressing
