Colombians are fascinating for the exactly reason you said the depth of high. Like punton rojo just randomly has cbd and is the starting point for haze! So many diverse climates having rainforest and crazy mountains like Santa marta. Been reading about austronesians dispersing out of Taiwan. There's some genetic and cultural evidence they could have made it to Peru on those outrigger canos based on a halplotype and introduced sweet potatos. But can't say for sure they came by sea technically could have walked over land bridge. Cannabis seems like somethin seafaring people would bring everywhere with them.
You have to take in account that the Punto Rojo the original Haze-grower bought came from a commercial grow, and just like the original haze-grower did when he started selling weed, the Columbians might have sold the purple plants as Punto Rojo and green plants as Columbian Gold from the same field.
So, imo, it could be wrong to assume the weed farm in Columbia was growing PURE Punto Rojo strain, it also could have been a sativa hybrid already in Columbia.
