Lemon Haze Auto pairs the zesty genetics of Lemon Haze with Barney’s Farm’s BF Super Auto #1, producing a 70% Sativa autoflower that runs from seed to harvest in 65–70 days.
With 24% THC, it delivers a long-lasting, energizing and euphoric high that suits daytime use. The flavor is the real star: zesty lemon with a hint of sweetness and earthy undertones.
Its modest size, 90–110 cm (35–43 in) indoors and 100–120 cm (39–47 in) outdoors, makes it a natural fit for growers with limited space. Yields reach 450–550 g/m² (1.47–1.80 oz/ft²) inside and 180–250 g (6.3–8.8 oz) per plant outdoors.
For haze fans who want a bright, motivating smoke without the long sativa bloom, this auto ticks every box.
Lineage: Lemon Haze and BF Super Auto #1
Lemon Haze is a citrus-loaded sativa known for its sharp lemon terpenes and an energizing, clear-headed effect. It has long been a favorite among haze enthusiasts.
BF Super Auto #1 contributes the autoflowering trait, hardiness and a robust root system. The cross keeps the haze brightness while cutting the timeline and the plant size dramatically.
Aroma, Flavor and Effect
The aroma mixes tropical fruit, sweetness and fresh citrus, with a zesty lemon note that grows stronger as harvest approaches.
The flavor is lemon, citrus and fruit, sharp and refreshing. It tastes like homemade lemonade with a splash of passion fruit, poured over ice on a hot afternoon.
Barney’s Farm lists the effects as uplifting, motivated and energetic. The 24% THC lands with a clear, euphoric push that keeps the mind engaged and the energy up. It works for daytime errands, creative work and outdoor plans.
Growing Lemon Haze Auto Indoors and Outdoors
Run 18/6 or 20/4 from seed to harvest; the plant flowers on its own without a light change. Sow into the final container, around 11 to 19 liters (3 to 5 gallons), to keep growth uninterrupted.
Indoors, the 90–110 cm (35–43 in) plant shows its sativa side with longer internodes. Gentle LST from week 3 keeps the canopy flat and the light even, which pays off at harvest. Feed moderately; sativa-leaning autos often prefer a lighter hand. With good lighting, expect 450–550 g/m² (1.47–1.80 oz/ft²).
Outdoors, plants reach 100–120 cm (39–47 in) and produce 180–250 g/plant (6.3–8.8 oz/plant). Full sun brings out the strongest lemon terpenes, and the 65–70 days cycle allows more than one crop per season in warm US regions.
