Description:
The cannabis cultivated in Ban Bueng Khong 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 Ban Bueng Khan 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 Phu Phan Mountains have long been a center for traditional cannabis cultivation, where local farmers have preserved this landrace for generations using open pollination methods. Cannabis from this region was historically part of the Thai Stick trade, supplying some of the most potent and flavorful exports of the 20th century.
Today, Ban Bueng Khan remains a key cultivation area north of the Korat plateau, though changes in agricultural practices have begun to affect the genetic stability of the landrace. Farmers have increasingly focused on producing seedless flowers, leading to excessive culling of male plants. This shift has resulted in a genetic bottleneck, where too few males remain to pollinate the population properly, leading to a higher occurrence of hermaphroditic plants becoming the dominant source of pollen.
Despite these challenges, the landrace retains its unique characteristics and we are making efforts to preserve and stabilize the original population through conservation breeding projects. By increasing male plant populations in controlled environments, a more genetically diverse and resilient seed stock can be provided to local farmers, ensuring that this historic lineage is not lost.

Bueng Khong General Population (2025)
Notes: Collected by Isabella in 2025
Type: General population, domesticate landrace
Altitude: 200m

Current Status:
There is an urgent need for conservation efforts to counteract the effects of male culling and reduced genetic diversity. To address this, a dedicated breeding project is being planned, where a large population of male plants will be cultivated in a remote area of the district.
The goal is to reproduce and distribute stabilized seed stock to local farmers, allowing them to continue their selection processes while ensuring the long-term survival of the landrace.
