Mass Medical Strains Thai Landrace Squirrel Tail Hang Karong
AVAILABLE 4/20/26
The Award-Winning “Holy Grail” of Pure Thai Sativa
For the true cannabis connoisseur, modern hybrids often fall short of the “magical” clarity and soaring energy found in old-world genetics. Mass Medical Strains presents a rare preservation of the Thai Landrace Squirrel Tail (Hang Karong)—a pure Sativa that dominated the Landrace Ganja Cup in Thailand.
Sourced directly from the cup-winning population via Prempavee, these seeds have been stabilized through a meticulous open pollination to preserve the authentic Thai experience while making it accessible for dedicated home growers.
The Profile: Carrots, Lacquer, and Light
This isn’t your typical “fruity” modern profile. This is an ancient, complex aromatic journey:
-
Flavor/Aroma: A nostalgic “old-school” vibe featuring notes of fresh carrots, industrial lacquer, and damp earth, brightened by zesty citrus, floral notes, and a deep, hazy backend.
-
The Effect: A pure, electric Sativa experience. If you are tired of the “heavy” ceiling of modern indicas, this provides a functional, psychedelic, and clear-headed high that only a 20-week Sativa can deliver.
Cultivation & “The Secret Sauce”
Growing a pure Thai landrace is an art form. While these are surprisingly stable and resistant to hermaphroditism, they require a specific approach:
-
The Light Cycle: DO NOT flower at 12/12. These genetics require at least 13 hours of darkness (11 on/13 off) to trigger and maintain flowering.
-
Management: Expect a 10x stretch. We recommend skipping the vegetative period entirely—start them on a flower cycle from seed.
-
Training: They are incredibly robust. You can top them aggressively, even during the flowering stretch, to manage height in a tent without sacrificing your high yield.
-
Feeding: Very light feeders. They thrive in standard organic supersoil and can finish beautifully even in small 1-gallon pots.
-
Breeder Tip: These plants perform exceptionally well under Metal Halide (MH) lighting, which helps mimic the high-UV environment of their homeland.
