Thanks for saying that Hempy, it’s very confusing with all the different ones named the same. You and @wallyduck @hammerheadgenetics might remember this grow I found, Billygoat growing out and making seeds with Viet Black straight from Fet in 2010, it’s a good documentation of the VB he used if people want to dig into it:
In there he cites the Dutch Flowers strain description for Vietnam Black that he found and acknowledges that it could be a different one, but the lineage he found is interesting:
Nam F1 (Vietnamese sativa hybrid, aka Vietnam Black, aka NAMweed) -Original F1 cross: -Male Northern Vietnam/China Boarder (indica influence) -Female Southern Vietnam outskirts of Saigon (truebreeding pure Sativa NAM) Breeder’s description
There’s that Yunnan indica border influence…
Looks like the Dutch Flowers is a South/North Viet cross, of a lowland pure sativa mother with a highland sativa-dom hybrid containing some percentage of Chinese indica.
Any time I say “Yunnan” I feel obligated to tag the Cangshan Man himself @zephyr
