This is an interesting concept that I have never considered in the "traditional RSO" process I think I may try this in the future and experiment and compare to my cold washed and winterized RSO? Yes my cold washed and winterized oil is not the fastest easiest most economical method but it is the strongest best tasting dabbable RSO I have tried but I am interested in trying your Co2 hash method... It's what I used to help cure 2 different stage 3 lymphoma cancers in two years time....Potent stuff, I'll do a post on my method soon as. Excellent initial OP and excellent comment and concept "thecleangame". Let's all further build this cannabis community here on steemit.
