All of the following micron sizes for 5-gallon water hash bags are available online as of October 2010, except those four marked with an * which are micron sizes that happen to be listed in the 15-bag pictorial in Jorge Cervantes' cultivation Bible. These latter, I assume, are made in the Netherlands and I just haven't seen a link to them, or they are no longer made.
I divide the bag sizes into categories.
THE WORK BAGS
230μ --Only saw this size offered by two companies.
220μ --This is the common size for the workbag, but Dropbags makes a 230u and some larger sizes, up to 400u (suited for different plant material, just saying).
200μ
190μ --I recently acquired an "extra-thick", "less flexible" 190u size BubbleBag brand bag that was half the price of their normal "replacement bags". This could be useful to hold the 220u bag in place if you're separating the work bags from the smaller sizes containing hash in a separate bucket.
185μ
180μ
COOKING HASH BAGS
(The following size bags are generally considered only good for cooking, adulterant for good hash for sale, or mixed with 25u and given away to friends.)
160μ
150μ*
135μ --I haven't seen this size used, but I would think that even if cleaned up well before passing, this size would still be low grade, not sure though.
TRICHOME/HASHISH COLLECTION BAGS
(Yum.)
120μ --Generally considered the start of what you want. Trichomes form Sativas will collect more on the smaller size bags, whereas with indicas you will see more quality stuff at this layer.
110μ
104μ*
100μ
90μ
86μ
75μ
73μ
72μ
70μ
66μ*
50μ
49μ
45μ
43μ*
THE FINAL BAG
(Anything that drains below the final bag is not worth collecting, so the size of the final filtering screen is important. This final bag is a low yielder and is most often considered lower-quality than the above micron sizes. Higher-quality when using a sativa as starting material.)
38μ --This seems like it would be a great alternative to the more common 25u size if the quality of the 25u was substandard. I'd like to add this one to my own lineup; this bag is also from the second most expensive set of bags I've seen available: The Icemaster AKA Ice Master AKA Bubble Master AKA Ice-O-Lator will set you back $340 for a seven bag set, or $60 if bought individually.
25μ --The common size most often used as the final bag.
20μ --Sounds tiny to me, but I haven't done runs with small-gland sativa material before. Only saw this size listed from the Weedbag brand of bags.
SPECIAL MENTION
1. I didn't use Ebay as the source for any of this information on availability, and you should not waste money on cheap or counterfeit bags offered at any auction sites.
Please contribute any sources/sizes I may have missed, also, someone shoot me a link for Scwagg Baggs brand, I couldn't find a site for there bags and don't know what sizes they offer.
2. Special mention has to be made here of the most-expensive bags I've ever seen or heard of, brand: Crystal Catcher Herb Bags. This is a 4-bag set with one major fuck-up in the design, as far as trichome collection goes anyways; see if you catch this in the following list of there bags' micron sizes:
220μ
70μ
49μ
25μ
Obviously lacking a filter in the "Cooking Hash" range. Oh yeah, and this 4-bag kit will set you back $260+. Insane.
3. When you hear of folks using more than eight bags for a run, they are running the material first in a series of workbags in one bucket, than the hash-laden water is run by itself through a second series of bags in a second bucket. This is sometimes referred to as a "second-run" but is not to be confused with a second run of the starting material itself.
The first bucket of workbags will start with a 220μ bag to mix in and end with something in either the 190u or 160μ range. I am starting to use my new sturdier 190μ bag as the final bag in my first bucket, and having a 190μ bag of normal, more flexible fabric as the first bag in the second bucket.
