PURPLE INTHANON

PURPLE INTHANON – 10+ SEEDS

Purple Inthanon – primarily refers to a rare, native Thai landrace strain originating from the mountainous Doi Inthanon region. It is used in breeding for its robust, tropical characteristics.

Purple Inthanon is a rare Thai landrace strain, specifically a heirloom variety sourced from the mountains of Doi Inthanon (the highest mountain in Thailand). It’s preserved by an old farming family in a secluded area of the Inthanon mountain jungles, isolated from modern hybrid gene pools. This strain is notable for naturally developing purple hues in its buds and foliage, likely due to anthocyanins expressed in the cooler high-altitude conditions of its native environment (unlike many purple strains that require cold stress to show color). As a pure Thai landrace, it’s likely sativa-dominant (Thai landraces are typically sativa), with characteristics common to Thai varieties: tall, stretchy growth, airy buds, long flowering times (often 12+ weeks), and uplifting, cerebral effects. Specific details like exact levels, terpene profiles, or detailed effects are limited since it’s a preserved heirloom rather than a widely commercialized strain. It’s offered as a pure landrace for collectors, breeders, or those seeking authentic Southeast Asian genetics. Breeders often use it in crosses for its resilience, purple traits, and exotic qualities.

No widespread user reviews or detailed lab-tested profiles (e.g., /CBD percentages, dominant terpenes) appear in common databases, as it’s niche and not mass-produced.

Effects would likely lean toward energetic, creative, and psychedelic (typical of Thai sativas), with potential fruity or earthy notes.

If you’re growing, breeding, or hunting seeds for this one, it’s prized for preserving old-school Thai genetics in a purple form—definitely a gem for landrace enthusiasts!

Growing tips for Purple Inthanon

Purple Inthanon is a pure Thai landrace sativa from the high-altitude Doi Inthanon region (2000+ meters), where cooler mountain conditions naturally trigger purple hues via anthocyanins without needing extreme stress.

Characteristics Type: Pure sativa landrace (Thai genetics)
Flowering Time: 12–16 weeks (very long—typical for Thai sativa; don’t rush it!)
Height: 6–10 feet (1.8–3 meters) outdoors; very tall and stretchy indoors (expect 3–4x stretch in flower)
Yield: High potential outdoors in ideal conditions; moderate indoors due to airy buds
Terpenes/Effects: Mango, citrus, menthol; cerebral, racy, euphoric high with eventual inner calm
Purple Expression: Naturally occurs in its native cool, high-altitude setup—often shows without forcing, but cooler nights enhance it
Growing Environment Outdoors (ideal for authenticity):
Mimic northern Thailand’s June–January season. Start in late spring/early summer for long veg under increasing daylight, flower naturally as days shorten. It thrives in humid, warm summers transitioning to cooler falls/winters. High humidity tolerance (from jungle origins), but ensure good airflow to prevent mold on dense colas. Full sun is essential—landraces like this love equatorial-style intensity.
Indoors:
Challenging due to height and stretch. Use a large space or train aggressively. SCROG (Screen of Green) or LST (low-stress training) early to control height and maximize light penetration. Hydro or soil both work, but soil may suit its natural resilience better.
Temperature:
-Veg: Warm days (75–85°F / 24–29°C), nights not too low.
-Flower: Maintain a 10–15°F (5–8°C) day-night differential to boost purple (e.g., 75–80°F day / 60–65°F night). Toward late flower (last 4–6 weeks), drop nights to 55–65°F (13–18°C) if possible for deeper purples—but avoid shocking the plant or slowing growth too much, as sativas are sensitive.
Humidity: 50–70% veg (humid-tolerant), drop to 40–50% flower to avoid bud rot on airy but potentially dense structures.
Lighting: High-intensity for sativas—strong LEDs or HPS. 18/6 veg
