China Yunnan Reg.

Description from Ace Seeds

China Yunnan Regular by ACE Seeds

This rare landrace variety from Yunnan, China, is a standout in the ACE Seeds collection. Unlike traditional Afghani hashplants or tropical sativas, it uniquely blends characteristics of both, showcasing a distinct regional identity and robust breeding potential.

China Yunnan typically grows as a sturdy, compact plant with broad leaves and a resin-rich structure reminiscent of hashplants. However, some plants may display sativa-like traits, including taller growth and narrower leaves. This natural variation within the population makes it a valuable landrace line, rich in genetic diversity.

It flowers relatively quickly and produces generous amounts of resin when grown under stable temperatures, dry conditions, and adequate nutrients. Cooler finishing temperatures may slightly reduce yield but can enhance resin quality. This adaptability highlights its usefulness not only as a cultivar but also as a genetic foundation for breeding programs focused on structure, resin production, and ripening behavior.

The aroma of China Yunnan is distinct—woody, resinous, and often layered with notes of incense, cream, and a subtle sweet-sour complexity. It doesn't conform to typical western cannabis profiles, which adds to its allure and makes it a prized entry in the ACE Seeds lineup.

Chemically, most plants exhibit high THC levels with low CBD, though occasional individuals may show a more pronounced CBD presence. This variability makes China Yunnan appealing to both growers interested in traditional Asian genetics and breeders seeking population-based diversity and unique chemotype potential.

With an indica dominance of 80% and sativa of 20%, this strain has a THC range of 8.5-17.22% and a CBD range of 0-8%. It flowers in 8-9 weeks, typically ready for harvest in late September to early October.
