You could do a clean up sift of the kief after, sift it over a 25 micron bag and some of that green dust will fall out

Thanks! I will try the 25 micron screen. I have a set of ice water hash bags somewhere. Just a matter of remembering where I put them.

Have you tested this?
Potency analysis?
Was trying to make a cheap safe low tech kief extract. Was going to try this …
1.Chill ethanol with dry ice.
2.Add kief slowly while gently stirring.
3.Gently stir for ( not sure how long)
4.Pour chilled ethanol and kief mix threw micron bag
5.Collect the ethanol
6.Squeeze the bag ( wine/cider press) into a different vessel from the main batch of collected ethanol.
7. Pull Vac on cls
8. Run the ethanol threw the cls and crc the way u traditinaly would with bho
9. Distill off ur ethanol ( seems like u can do this with 98ish degrees water and a traditional coil back to recovery tank but I assume it would take for ever? So probably need a pump? )
Point of this is to beable to get decent yeilds with a 1 lb material column and a few gallons of ethanol
