DenverLosGrow and I decided to do a little experimenting with making Butane Hash Oil(aka BHO, Honey Oil, etc). We each did a separate batch with our own trim. We started out with fresh frozen trim and used the dry ice method to extract the trichomes from the plant matter using a 220 micron bubble bag. Next, we took excess plant matter and used it as a base and layered kief and trim. This method only worked out "okay". I got a much better return then Los because he was a little hesitant to sacrifice a lot of beautiful golden kief.
