Description:

The cannabis cultivated in Phon Sawan 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 Mekong river banks.

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 Phon Sawan 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 flat agricultural land inland of the Mekong in Nakhon Phanom province has 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, Phon Sawan is a shadow of its former self, yet it remains a key cultivation area. However, 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.

Current Status:

The Phon Sawan landrace is on the brink of extinction. Fewer farmers are cultivating it each year, leading to a severe genetic bottleneck. The introgression of foreign genetics from modern hybrids is a growing concern with several active growers in the area cultivating modern varieties, threatening the purity of this ancient lineage.
