I strongly suggest every bag owner to check their bags because the size of the openings on the sieves can be way different than the seller claims.


This means you might be flushing your hash down the drain, smoking leafy hash or simply a different quality you might wanted to smoke.

When I used my bags for the first time I left the water in a bucked after the procedure. I noticed that there was still a lot of residues collected on the bottom of the bucket even after it was screened with the 25 micron bag. So I checked the bags with a cheap microscope and compared the size of the openings on the sieves with a millimeter scale. I noticed it was way off so bought a stage micrometer and measured the holes on the screens.

4 bags costs more than 100$ so I wouldn't say it's cheap. The seller told me it must be the the manufacturer's fault, and sent a new set of bags from the new batch a couple month later, but these were still off the scale.

2 sets of bags + pressing screen + some sieves straight from the manufacturer.


Stage micrometer:


25um bag is 86um in reality:


25um bag is 70um (from the new batch):


25um pressing screen is 74.5um


75um bag is 81um


75um bag is 89um (new batch)


110um bag is 132um


220um bag is 174um


220um bag is 313um


This is a printing sieve straight from a manufacturer. I bought it as a 31 micron sieve, and it's also written on the screen itself so there is no doubt about that.


This means the measuring method works and exact.

First I used a millimeter scale printed on paper so the measurements are not precise, but the scales are visually comparable, so you can see what happens to a sativa or indica gland.



Residue at the bottom of the bucket after the "25" micron sieve and some settling and siphoning:


Leafy shit:


So anyone who has a 80 micron bag instead of 25 micron might be pouring the best quality hash down the drain while his hash is made up mostly from powdered leaves.

I used ImageJ (opensource freeware) to process the images and make the measurements:

Anyone can check the bags with a cheap microscope or with a decent camera, some microscopes with a known field of view can be used without buying a stage micrometer (costs couple of dollars)

Measuring the usual way:

These bags are still sold on the web, the seller told me he sells 1 set per day. I won't say what brand is this, so everyone will have to check his own. Either way these bags could be sold under an other name, so it's better to check your own.

BHO FTW

thanks for the heads up though, looks like you did some good work...

what make of bags are they ???

[BigSteve]

This happened to me a couple years ago. Ever since then I make sure nobody around me orders generic crap.

I did a couple runs because I thought I must of made a mistake.

BUBBLEBAGS FTW!

dont use knockoffs

[Hammerhead]

What about the original Bubble bags. What do those measure at ???

[HerbalToker]

Buy Bubblebag brand Bubblebags. Avoid your problem. They are the best for a reason.

Puff on

wow interesting, i wouldn't be able to control myself and tell which companies bags they are. but yeah people should check theirs, specially if they see residue in the water after the 25 bag. you should have nothing but colored water left. have also read some bags sieves will stretch with time. i will check my bubbleman bags one of these days, just to be sure, but they still worked as efficiently as ever last time i used them. i guess that's one of the things you are paying for in the end, reliable workmanship and durable quality material.

Send me a set of Bubblebags and I will measure it for you
Or you can measure it for yourself, I guess it would be cheaper to buy a microscope for yourself than buying a set of bags for me, but it's in your hands man

If I write the brand I'm sure some people would come forward claiming they never had any problems and I'm just a hater, just because I used some crappy weed etc.
The company also can set up an other webshop under a different name and sell these same shitty bags.
Other companies might also selling low quality bags like this so it's better to check as much as we can.
Batches can also be different, so a group of people might be ok while others who bought a different batch might be cheated while they using the very same brand of bags.
So these are the reasons behind the decision why I won't say the brand of these bags.

lol I dont think so yo can buy your own like I did. I just dont have a way to measure them. Im not going to waste money on a scope. You know you have a bad set so what are you going to do. Get a good set of Bubble bags and measure them. If the bags you measured are Bubble bags then you should let us know about that.
