It may have been about rehydration before washing, that’s what i’ve failed to do when running dry/cured trim. Apparently you need to rehydrate dried material in chilled water with no agitation 30+ minutes prior to transferring to the wash bag for best quality and good yield. When running fresh frozen it’s not necessary to rehydrate.When I got a really bad yield I read somewhere that you need to agitate for much longer than 20 minutes but I cannot find that article now? It has been quite a few years ago. Maybe that was with soak time also. Now I don't know but I know 20 minutes did not work for me.
I stopped doing the wet extraction because I kept loosing the trichomes to mold. I could not get it dry fast enough but that is a separate problem.
