About American Haze Auto
The way to plan American Haze is backwards from the day you intend to cut, with 300–500 g/m² per square metre indoors and 350–450 g/plant per plant outdoors as the figures you are working toward, at 24% THC. Count 7–9 weeks from seed back from that date and you have your flip date. This one does not dump its weight in a fortnight the way a short indica will; it adds through the whole bloom. Growers who panic about autumn rain and chop a fortnight early routinely hand back a fifth of the crop. Depending on your province the honest window runs from late March into May, and the pinene-led profile only arrives in the last fourteen days.
The Aromatic Three
Leading with Pinene, then Limonene, and Caryophyllene underneath.
Difficulty: intermediate. In flower for 7–9 weeks from seed. Stands 120–160 cm. Indoors it returns 300–500 g/m². Outdoors, 350–450 g/plant a plant.

American Haze Auto — Breeder Information
Royal King GeneticsRecreated and stabilised by Royal King Genetics, the breeding team behind this catalogue. Seed lots are germination-tested before they ship. More on the breeding process and about page.
Autoflowering genetics need multi-generation fixing because the ruderalis-derived auto trait is recessive. American Haze sits at F5 — every plant in the pack autoflowers reliably and finishes inside a tight window.
Stabilise the recessive ruderalis trait in American Haze for uniform auto-trigger.
Chosen for sativa vigour, bud-to-leaf ratio and the distinctive terpene character of the original cut.
