About Alien Reunion Auto
The most common mistake growers make with Alien Reunion is treating it like a simple "set and forget" cultivar. While ${name} is forgiving, the ${indica}/${sativa} balance means it responds noticeably to feeding adjustments at the veg-to-flower transition. Growers who continue veg-ratio nutrients into early flower miss 10-15% of this strain's yield potential by not switching to bloom feed when the first pistils appear. At 18% THC with myrcene-dominant terpenes, the quality ceiling is high, but you have to manage the specific characteristics of this cultivar to reach it.
Growing This Strain: Where Things Go Right and Wrong
The three most common issues growers report with Alien Reunion:
1. Nutrient timing at the flip. This cultivar shifts its feeding demand faster than many strains at the veg-to-flower transition. Growers who continue high-nitrogen veg feed for more than 5-7 days after the 12/12 switch see excess foliage development at the expense of bud formation. Switch to bloom nutrients within the first week of seeing pistils.
**2. Training timing. Topping too late or too early both cost yield. The sweet spot: top at the 4th node when the 5th is just emerging. This gives you 4-6 strong laterals that develop into even colas. Earlier topping produces weaker branches. Later topping wastes veg time.
3. Harvest timing. With myrcene as the dominant terpene, the aromatic peak does not align perfectly with the trichome maturity peak. Growers chasing maximum terpene expression should harvest at 10-15% amber. Growers prioritizing potency should wait for 15-20% amber. These are different windows, know which one you are targeting.
Flowering: 8-10 weeks. Yield: 350-450g/mΒ² indoor / 500-700g/plant outdoor. Height: Tall (4-5 ft). Difficulty: intermediate.
What Users Report
Alien Reunion at 18% THC produces creative, calm sensations that users consistently describe as versatile enough to serve different purposes depending on dose and setting. Lower doses lean more cerebral and functional. Higher doses bring the body effect forward. The Myrcene/Limonene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other hybrids at similar THC levels.
Best suited for flexible use across the day, lighter doses for daytime function, heavier doses for evening relaxation.
Terpene Profile
Dominant terpenes: Myrcene (primary), Limonene (secondary), Pinene (tertiary). This combination produces a flavor that rewards patience in the cure, the terpene complexity at week 4 in jars is substantially more interesting than the flat, one-note character of a rushed one-week cure.
Who Should Grow Alien Reunion
This strain fits growers with at least one harvest behind them who want to step up in quality without dramatically increasing complexity. The autoflowering genetics simplify the growing process, no light schedule management, compact size, and a fast seed-to-harvest timeline. Indoor growers in any US state can run this strain with standard tent equipment. Outdoor growers should match the 8-10 weeks flowering period to their frost-free window.
