the 25 micron bag is a waste of time all it catches is the dust. (in my opinion)
we have made lots of ice o later,bubble hash,water extraction etc.
and never keeped any of the 25. the other day i got to have with Sadu Sam and he explained
that the 25 is the dust catcher.
so i suggest not to waste your time and help your back out too by not using the 25
