Hau Bac, also known as Viet Silver Flower, came to us around 2007 from our good friend Vu in Vietnam. This pure Vietnamese sativa landrace is one of the strongest and most exotic sativas we’ve ever worked with. We always recommend growing it straight rather than hybridizing it to preserve its true character.

Plants grow tall and stretchy with a beautiful silvery sheen on the buds — hence the “Silver Flower” name. Long airy colas with large calyxes and heavily frosted side buds that look like silver firecrackers. The high is extremely potent: clean, powerful, and classically uplifting with distinctive tropical Vietnamese flavors.

Flowering Time: 12–14 weeks (some phenos push longer). A rare Southeast Asian heirloom gem for serious sativa lovers.
