a pure Thai would be somewhat similar ... my Willie Nelson is 50% Vietnamese Black, I don't know of anyone carrying a pure 'Nam weed ... regardless, the Viet and Thai are a plant best left to very experienced growers ... intolerant of stress, and hermie-prone, plus, it needs a tolerable climate for a plant that takes 14-20 weeks for flowering, and if indoors, 20-foot ceilings ... (I love 'Nam grass, but won't likely be growing it again) ... :smokin:
