Santa Marta Haze Auto brings Colombian sativa heritage into an autoflowering format without losing the soaring haze character. Seedstockers lists three cup results for it: 3rd Best Autoflower at the Highlife Cup, 1st Best Sativa Indoor at the Copa Del Sol, and 2nd Best Sativa Strain at the Autoflower World Cup.
It is a tall, vigorous sativa-dominant auto with THC of 20–26%, a fruity-spicy terpene profile, and massive yield potential, finishing in roughly 11 weeks from seed. It rewards growers who give it room and train it early.
Lineage: Santa Marta Haze × Amnesia Auto
Santa Marta Haze Auto comes from Santa Marta Haze × Amnesia Auto. The Santa Marta Haze side traces back to elite Colombian sativa genetics, while the Amnesia Auto parent brings the automatic flowering trait and a classic haze kick of its own.
The breeder’s goal was to keep the long, lifting haze effect and exotic terpenes of the photoperiod ancestor in a plant that flowers by itself. The result keeps the classic sativa frame, with long internodes and a strong stretch, on an autoflower schedule.
Aroma, Flavor, and Effect
The aroma is a bright fruity-spicy bouquet with an earthy undertone that hints at its Colombian roots. It opens up noticeably after a proper cure, so patience in the jar pays off.
The flavor is sweet tropical fruit with peppery spice and a hint of incense on the exhale. It is complex and unmistakably haze, the type of smoke that keeps revealing new layers as the session goes on.
The effect is a clear-headed, powerful sativa rush that sparks creativity and motivation. It is a daytime strain built for getting things done, with a long, euphoric finish that keeps you engaged rather than sedated.
Growing Santa Marta Haze Auto Indoors and Outdoors
No light switch is required. Keep Santa Marta Haze Auto on 18/6 or 20/4 from seed to harvest; Seedstockers runs it on 20/4 under a 600 W LED. Plan for vertical space, because the plant can stretch past 120 cm (47 in).
Indoors, expect 500–600 g/m² (1.64–1.97 oz/ft²). The breeder recommends starting LST early, around day 14–18, to open the canopy and push light to the lower branches. Light defoliation in weeks 3–4 of flower improves airflow through the dense canopy. It becomes a vigorous feeder once bloom starts.
Outdoors, plan on 150–300 g/plant (5.3–10.6 oz/plant) in warm climates with long sun hours. It thrives in Mediterranean and subtropical conditions, and staggering sowings a few weeks apart makes several harvests per season possible.
