Hexane extraction


#1

Does anyone have experience extracting thc using hexane at ultra low temps (-80c)? If so, how is the color of your crude, what are your yoelds, and do you have to winterize? I’m wondering if hexane would be a good substitute for ethanol. I have an ethos 4 set at -70c, I don’t have to winterize, but I’m still pulling chlorophyll.
