As I understand isomerizing with Bentonite would yield both 8 and 9 [CBD and CBG conversion to Delta 8 and 9 - #2 by Kingofthekush420], or have I misunderstood something there? So basically using acid leeched bentonite (which I would have to make myself) would pretty much yield the same amount as using H2SO4, just with a lot less hassle?
