Royal King Genetics β€” first-party test batch

Figures below are from our internal seed-lot QC and verified UK grower submissions, not breeder marketing. Determined from a single batch tested 2026-09-20 on 375 seeds.

Germination rate: 96.7% (n=375)
Last QC test date: 2026-09-20
Indoor yield: 486-610 g/mΒ² (avg across 14 verified grower reports)
Outdoor yield: 642-1000 g/plant (avg across 9 verified grower reports)

About Alien Rift Auto

Germination and early veg, days 1-14. Alien Rift seeds generally crack inside 48 hours on damp kitchen roll and break the surface around day three. Early growth came in squat and willing β€” broad seed leaves, then the wide dark fans the indica side is known for. Four nodes by day 14 with the internodes already tight. Damping off is rare around 70% relative humidity, which is also roughly what an unheated British room sits at in spring.

Veg, weeks 3-6. Side branching took off after a top at the fourth node. The plant held a 60cm square by week five and stayed under 40cm tall, which is the shape you want in the small tents most people actually own.

Bloom, weeks 1-10. This is where the 65/35 balance in Alien Rift showed itself. The myrcene came up in week three and kept building; trichome cover was obvious to the naked eye from week five. Indoor yield: up to 350 g/m2. THC testing at 23%. Rated intermediate.

The rest of the diary

Mid-bloom, weeks 4-6. The change came quickly. Sites that were loose and wispy at week three closed into defined colas. Density went up almost daily; by week five a developing bud squeezed like a firm rubber ball. Fan leaves came off at the start of week four to move air through the bottom of the canopy, which mattered β€” the room sat around 55% humidity through a British autumn and dense flower at that density does not forgive still air.

Ripening, weeks 8-10. Feeding dropped to plain water for the last ten days. The myrcene got strong enough that carbon filtration stopped being optional in a terraced house. Trichomes ran clear to milky across the final fortnight, amber showing on sugar leaves first. Around 15% amber on the calyxes is a common place to stop.

Drying and curing. Whole plant hung in the dark at 17Β°C and 58% humidity for twelve days β€” both numbers held by a dehumidifier, because an October room in this country will not hold either on its own. Stems snapped rather than bent, which is the test worth trusting. Four weeks in glass followed, burped twice daily for the first fortnight and once daily after. Final weight matched the up to 350 g/m2 figure. The caryophyllene was far more present after the cure than at harvest, which is the argument for curing properly: the process makes flavour rather than merely keeping it.

Flowering: 60-70 days. Indoor yield: up to 350 g/m2. Outdoor yield: up to 350 g/plant. Rated intermediate difficulty. Regular seeds with autoflowering genetics.

Flavour, aroma and effect

Alien Rift arrives in stages. The first draw at 23% THC brings a musky earthiness that coats rather than cuts. The relaxed, sleepy, happy character follows within minutes, starting as weight behind the eyes and working down through the shoulders and chest. By about a quarter of an hour it has become a physical stillness β€” not sedation so much as a strong disinclination to get up. Two to three hours at a moderate dose. The caryophyllene underneath adds a warmth that keeps the whole thing anchored.

Terpene breakdown

Primary: Myrcene Β· Secondary: Caryophyllene Β· Tertiary: Linalool. These three build an aroma that keeps moving through the cure. Fresh off the dry it leads with myrcene; after three or four weeks sealed in glass at 16-18Β°C the linalool underneath comes up and the whole thing gains a layer. Vaporising between 180Β°C and 195Β°C catches the widest span of them, since the lighter linalool molecules are the first thing heat destroys.

Who it suits

Who does well with Alien Rift? Balcony growers in flats from Brighton to Glasgow. Anyone wanting one quick outdoor crop rather than a long project. Indoor growers short of headroom. The autoflowering genetics run on their own clock, so there is no light schedule to manage, no anxiety about light leaks, and harvest comes 10-12 weeks from germination whatever the season is doing. Difficulty is rated intermediate, which means a moderate learning curve that rewards attention without demanding a laboratory.

Stabilisation Notes β€” What This Means for Your Grow

Alien Rift is our F5 autoflower line. Five rounds of selection have fixed both the autoflower trigger and the trichome saturation the cultivar is known for. The recessive ruderalis trait demands this depth of work to express uniformly.

Breeding Goal

Reach auto trigger and finish-window uniformity for the Alien Rift pack.

Selection Focus

Chosen for indica vigour, compact bud formation and a reliable finish window.
