Do you just put all the stems in a jar full of iso and leave it there for days? Seems to be the trichs don't come off so easy. Something I noticed during my washes.

Youre not going for the Trichs with this method. Forget about em. I just take my stems, grind them up by hand (Not too fine as to pass through a coffee filter). Stick em in a small mayo jar, cover about 1/2-3/4" with ISO or Everclear, shake for 30 secs, then filter and make as per many guides reccomend. The only thing i do different is i just leave it in my pyrex and smear papers etc in it soaking it up.

All in all, very very good use for stems. (Btw ive even used everclear, then what ive done is evapped most of the alchohol away, and then added it to some simering butter....the results were mind blowing)

And i also do a second wash, where i just leave it in there for days....but the final product is far inferior to a 30 second wash
