Royal King Genetics — Seed-Lot Testing
Figures below come from our own seed-lot testing rather than breeder marketing, taken from a single batch tested 2026-01-31 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.
Bloom Through to Jar
Weeks 4 to 6. This is where the plant stops looking like a frame and starts looking like a crop. Density climbs almost daily — by week five a developing cola should feel firm rather than springy under light pressure. Pull the fan leaves shading the lower canopy at the start of week four, which matters more than usual if the room is sitting near 55% humidity through a damp autumn.
Weeks 63 to 65, ripening. Drop to plain water for the final ten days. The myrcene carry gets strong enough that carbon filtration stops being optional in a residential street. Trichomes run clear to milky across the last fortnight, amber showing on sugar leaves before it reaches the calyxes; around 15% amber on the calyxes themselves is a common place to cut.
Drying and curing. Whole-plant hang in the dark at 17°C and 58% humidity for roughly 12 days — when stems snap instead of bending, it is ready for glass. Burp twice daily for the first fortnight, then once daily through weeks three and four. Finished weight should land near the up to 300 g/m2 estimate. The humulene note comes through markedly stronger after curing than it did at harvest, which is the clearest evidence that a cure builds flavour rather than merely preserving it.
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. Regular seeds with autoflowering genetics.
What Crown OG Is Like to Use
The effects most commonly reported for this cultivar are euphoric, creative, calm. At 20% THC it sits in a bracket where the dose does most of the work. A single bowl vaporised at 185°C gives a manageable body relaxation with your head still intact — enough to close out a long day in the summer heat. Push the dose and it moves decisively toward physical sedation, which is how it tends to end up as a winter evening cultivar. The Myrcene/Humulene pairing leaves an earthy sweetness with a fruit finish on the palate.
Where it fits: quiet evenings, a film, recovery after exercise, and the hours before sleep.
The Aromatic Three
Leading with Myrcene, then Humulene, and Linalool underneath. Read across a cure, these three compounds do not stay in the same order. Fresh off the dry, myrcene leads. After three or four weeks in sealed glass at 16-18°C the linalool undertone comes up and the bouquet gains a layer it did not have at harvest. Vaporising between 180°C and 195°C captures the widest span of them — run it hotter and the volatile linalool molecules are the first thing you lose.
Suitability and Recommendations
Crown OG is a reasonable fit for growers with the basics already in place. Understand pH, know roughly what nutrient ratios do, and be able to hold a light cycle — it will not carry you, but it does not punish the occasional slip either. Because it autoflowers there is no light cycle to manage at all, which is what makes it work on a balcony, in an out-of-the-way outdoor spot, or anywhere a timer would be one more thing to go wrong. A September-to-May outdoor season comfortably covers a 55-65 days bloom in the frost-free provinces. Posted discreetly anywhere in South Africa, with sourced grow figures shown on every strain page.

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.
