just to clear the air from confusion and before you all go making a legend from myth here is how it was done and is done still....
Nh is made from Haze C male which is made by two pure haze parents from 1969....then the female side of NH is made from Haze A combined to NL5 or NL5Haze A where Haze A was also made by two pure Haze parents also from 1969
Haze A is no longer alive only Haze C male is along with several other different sativa lines.
but plants with the lineage of Haze A are still alive and carrying the genes within.
SSH is made up of Haze C combined to Skunk 1 or Skunk HzC which is the male side, the female side is Haze C combined to NL5 or NL5HzC
the Mango comes from a parallel cross same as SSH but with one difference
Haze A male combined to Sk 1 or Sk HzA being the male plant, the female is NL5HzC....that is the breeding of those three plants
considering the Haze A is no longer a male alive, it still is alive in the ancestry of some of the plants used in all these breeds
I do not have secrets about breeding but given the same seed batches we could all still create something different...it boils down to selection.
