Description:
The Khiriwong landrace, also known locally as Meun Sri, is an ancient Southern Thai cannabis population traditionally cultivated in the Khao Luang Massif. Among the last true Thai sativas from the region, this population carries the botanical and cultural memory of a disappearing world.
 
These plants grow tall, sometimes reaching six metres in historical fields. They have slender frames, long internodes, and narrow leaflets. Their open-flowered structure is adapted to the humid rainforest conditions of the southern mountains. Aromas are intense and tropical: overripe mango, sharp citrus, and a dry, earthy spice that lingers in the nostrils.
 
The effects are classic tropical sativa: bright, euphoric, and long-lasting. There is no couch-lock here, only clarity, uplift, and a buzzing mental focus. It’s the kind of high that makes you want to build something, write something, or walk until the sun sets.

Context:
 
Khiriwong village lies nestled at the foot of the Khao Luang massif, surrounded by steep forested hills, fast-moving rivers, and some of the cleanest air in all of Thailand. The massif is the highest in Southern Thailand and as a part of the Tenasserim Hills - forms the heart of the Nakhon Sri Thammarat Range. Its slopes are draped in dense lowland rainforest, and its peaks are crowned with a wreath of rare tropical cloud forest. These mountains are a refuge - for plants, for animals, and for people.
 
For decades, the rugged terrain and remoteness of the region offered sanctuary to all kinds of outsiders. Poachers, fugitives, dissidents, communists, anarchists, and ganja farmers all found shelter here. In the 1970s and 80s, during the communist insurrection in Southern Thailand, the forests around Khiriwong became a hiding place and a base of operations. Small communities lived off-grid in the mountains, cultivating vegetables, fruits, and cannabis to survive.
 
It was in these highland clearings that Meun Sri was grown - sometimes in secret jungle fields, sometimes intercropped among fruit trees. The cannabis wasn’t just a crop. It was currency, medicine, ceremony, and survival. It paid for school fees and funerals. It treated wounds and eased minds. It was passed around in bamboo bongs during long nights under the stars, pressed into bamboo tubes with resin-darkened hands, and carried down jungle trails to be traded in the lowland markets.
But those days are long, long gone now.
 
Following legalization, cannabis made a brief return to Khiriwong. A handful of older and younger farmers revived large outdoor fields, and a few greenhouses and indoor setups appeared. For a moment, it felt like a revival. But it didn’t last. Hybrid flowers from the city were easier to sell. Consumer tastes shifted. Modern smokers wanted fruitier, heavier highs. Landrace plants took too long, grew too tall, and demanded too much space. More than anything, durians and mangosteens brought in better income.
 
These days, most younger growers aren’t interested in Meun Sri. They see it as old-school—what their communist grandparents smoked while hiding from helicopters in the jungle. There’s a cultural disconnect, a generational gap between the landrace legacy and today’s cannabis market. The old fields have been cleared. The old knowledge is fading. And with it, the landrace genetics that once defined Southern Thai cannabis are slipping away.
 
Still, Khiriwong’s cannabis legacy isn’t entirely gone. A few seed jars remain in dusty kitchens. A few memories survive in the hands of older farmers. And maybe, just maybe, there’s still enough left to bring Meun Sri back.

Current Status:
 
Meun Sri is functionally extinct in Khiriwong. No known farms in the district maintain active landrace populations.
 
Our seed collection of Meun Sri may be amongst the last extant germplasm still viable.

5 Seed Packs of 10 seeds are available for sale. 

We are committed to bringing back this landrace back from the brink of extinction at our nearby research station, 20km away in Ron Phibun district.
