Introducing Our New Southern Thai Landrace Accessions: Khiriwong and Lan Saka

Past the last road, deep in the Khao Luang Massif, some of the last true Southern Thai landraces still survive and we just brought back seeds from two of their strongholds.

Each of these represents a unique thread in the story of Southern Thai cannabis: long, towering sativa plants bred by generations of farmers for resin, resilience, and a high that feels like it belongs to the jungle itself.

What Makes These Genetics Special?

• True Landrace Populations: These aren’t commercial hybrids. They're the real thing — old, regionally adapted cannabis populations that evolved under the rhythms of monsoon, mountain, and man.

• Direct from Farmers: We worked directly with local cultivators, not middlemen, to source seeds in their native environment — ensuring authenticity and genetic integrity.

• Conservation First: Many of these populations are at risk of disappearing, so our mission is simple: preserve, protect, and replant. Open-pollinated, seed-grown, no cloning, no bottlenecking.

  
  

Khiriwong Seeds

About the Accessions

Khiriwong:

Sourced from one of the last traditional cannabis-growing villages in the Khao Luang Massif, the Khiriwong population is part of what locals call "Meun Sri," the old mountain ganja. These plants are true tropical sativas, shaped by generations of farming in one of Southern Thailand’s most remote and biodiverse regions. In traditional fields, plants often grew five to six meters tall, their narrow leaves and long internodes adapted to the slow rhythms of the mountain seasons. Aromas vary across the population, with profiles ranging from sweet tropical fruit to sharp herbs and deep wood resins. The effects are clear, expansive, and long-lasting.

Today, traditional cultivation in Khiriwong has all but vanished. These seeds are likely among the last viable traces of a line that once thrived in the high valleys of Khao Luang.

Lan Saka:

Collected from old fields in Lan Saka district, this accession represents another surviving thread of the Meun Sri tradition. Like Khiriwong, the plants are tall, vigorous, and adapted to the long monsoon cycle of the mountains. Some individuals show slightly earlier flowering traits, a reflection of the natural variation that once allowed farmers to adapt their crops to shifting seasonal patterns. Aromas lean toward bright citrus, camphor, pepper, and mountain herbs, with occasional deeper resinous notes.

Cannabis cultivation in Lan Saka is now almost entirely gone, kept alive only in scattered fields and fading memories. Without preservation, this living link to Southern Thailand’s cannabis heritage would be lost.

Why It Matters

Thailand’s old ganja strains aren’t just “old school genetics.” They are botanical heritage — shaped by culture, climate, and history. Every time a farmer stops growing, or a mountain field is abandoned, another link to the past breaks.

We’re trying to hold the line and bring these plants back into the world where they belong.

These accessions will soon be available through the Zomia Collective.

Stay tuned if you want to be part of the preservation.

This isn't about nostalgia. It's about survival.
