Description:
The cannabis cultivated in Wang Yang district is a classic Lao-Isan (Mekong) landrace population, characterized by tall, elegant ‘sativa’ morphology, long internodal spacing, and high resin production. These plants reach between 2-3 meters in height, thriving in the warm, dry climate of the Phu Phan Mountains.
Two primary expressions are present in the population:
Tiger Tail (Hang Suea): Known for its bold, robust structure, this phenotype has thicker colas, strong lateral branching, and a dense trichome coating. The terpene profile leans toward earthy spice, herbal musk, and deep, woody undertones. Psychoactive effects are strong, clear-headed, and energizing, making it a highly sought-after selection for daytime use.
Squirrel Tail (Hang Krarok): A more delicate, elongated phenotype, producing cascading, foxtail-like colas and lighter, airier flowers. The aroma is sweet and floral, often displaying tropical fruit, mango, and subtle herbal notes. The high is uplifting, euphoric, and long-lasting, reflecting the classic cerebral effects of Mekong sativas.
The overall terpene spectrum within the population ranges from earthy spice to bright, sweet fruit, with notable mango and herbal overtones. The psychoactive effects remain clean, stimulating, and paranoia-free, making this accession a quintessential representation of Isan’s historic cannabis heritage.

Context:
The Wang Yang region's strategic location along the Mekong River facilitated cross-border trade with Laos, where similar Lao-Isan landraces were grown. This historical exchange enriched the genetic diversity of the Si Songkhram landrace, making it one of the most sought-after Thai sativas in the world. However, political changes and international pressure led to the criminalization of cannabis in Thailand, pushing cultivation into the shadows. Many traditional farmers abandoned their fields, leading to a severe genetic bottleneck. In recent years, the introgression of foreign genetics from modern hybrids has further diluted the purity of the ancient landrace.
