i primarily make my oil from Blue Dream trim and lowers. I purge initially with no heat till the blob doesn't muffin up anymore. then i'll bump the heat up to 95 and then eventually to 115 when the oil seems to not purge as much. it use to be that i could only make sap/shatter. honestly, i'm not sure what the difference is. all of a sudden i did a run and got honeycomb, then subsequent runs were sap/shatter again. the one determining factor for some reason is freshness. even the best oil makers i know about in my area can't do as much with the end result if the material is older. as to why freshness is such a factor, i do not know, but it has been the only difference between all the runs i've done and which was recently confirmed by a veteran oil maker.
