so what is your extraction efficiency?
grinding allows for more cannabis in the tube.
which means more extract in the bucket.
without testing the biomass and the extract, the only way of knowing if grinding increased extraction efficiency is to always use the same biomass.
you are correct that grinding tends to darken extract. the cannabinoids are in the trichomes. grinding opens cells. if you get more mass back from ground input, but it is lower potency (that color you pulled weighs something right?), was that a win? you can’t tell without 3rd party testing…(or In House analytics)
