Dude, my name is frank(82 though).
I've grown two HSO strains (TBK and Black D.O.G)...
Btw, If I had to recommend TBK or Black D.O.G, I'd recommend TBK. Unless you want "prettier" weaker weed. TBK terpene profile is super hardcore, THC is on the high end of the spectrum.
I have a strain called blue fire, not HSO (my brother named it)...
Shit's confusing.
FGL.
So I dunno what HSO's blue fire is, but that looks pretty heavy indica hey.
*Edit: I just checked the Blue fire profile, and it seems quite a bit like TBK tbh.
