more then name, the grower makes the greatest difference.
you can grow a beautiful pheno straight in to the ground if you don't try.
that does indeed look like Psio-Tronics PurpleHaze, i grow the G13Labs version. its genetics are often (Chocolate Thai x Haze#1).
the type i grow doesn't turn black purple like that, but vie had it a couple of times. for the odor it tastes surprisingly bight green, a sinus burner.
my TrainWreck turned Purples&Pinks, but, thats only because it was left on the vine so long... a trait, but not an identifying feature.
the PHaze i have stays green, and smells very floral, and perfume like, tastes the same also.
after being so dependent on it for multiple medical reasons, all strains are not created equal, and after enough experience whats what becomes obvious fast.
as a med patient, i don't want any damn Diesel, or BB id feel ripped off personally...
but the Phaze, Mr Nice, OG, these examples for myself are very helpful.
