i’ve been thinking about what @nobodysnursery said about the BAH not being that rare and a very recent, and fully tested, release and have kinda shied away from putting out massive amounts of f2s. it is one of doc’s flagship strains and one that he would most likely put out first if/when he gets up and running for seed making in mexico putting out f2s of the 3.0 could possibly ‘step on his toes’ and take sales away from him.
it looks like there is 1.5 packs of this available for a seed run from what everyone has posted, @Knifeman and @highminwin, and this would def qualify as rare and discontinued so it gets my vote for reproduction.
both @Jubal_harshaw and I have zang! x af/pak and going off @advancedbuffalo 's description and smoke report it gets my vote for a repro.
