Figures below come from our own seed-lot testing rather than breeder marketing, taken from a single batch tested 2026-09-18 on 225 seeds.
About Crown OG Auto
Days 1 to 14, seed to fourth node: Expect Crown OG to crack in roughly 48 hours on damp paper towel and to break soil by day three. Early growth comes in low and wide — broad seed leaves first, then the dark fan leaves the indica side is known for. Four nodes by the end of week two, stacked close together. Damping off is rare if you hold near 70% humidity through this stage.
Weeks 3 to 6, building the frame: Top at the fourth node and the laterals take over fast. A 60 x 60 cm footprint filled by week five is normal, still under 40 cm tall, which is what makes this workable in a small tent.
Bloom, weeks 1 to 65: The 70/30 character becomes obvious here. Myrcene usually shows in week three and strengthens from there, with trichome cover visible without a loupe from about week five. Indoor yield: up to 300 g/m2. Height: Medium. Tested at 20% THC. Difficulty: intermediate.
The Aromatic Three
Leading with Myrcene, then Humulene, and Linalool underneath.
Difficulty: intermediate. In flower for 55-65 days. Stands Medium. Indoors it returns up to 300 g/m2. Outdoors, up to 300 g/plant a plant.

Crown OG 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.
Crown OG is an autoflowering line that has been progressed through five rounds of Royal King Genetics autoflower stabilisation. The autoflower trait is recessive — fixing it takes multi-generation work — and at F5 the auto trigger and finish window are welded across the pack.
Stabilise the recessive ruderalis trait in Crown OG for uniform auto-trigger.
Chosen for resin output, a low-slung stature and a clean indica terpene fingerprint.
