About Night Train Auto

The genetic expression of Night Train — a 54/46 hybrid — varies meaningfully across phenotypes. Most seeds from this line produce the dominant phenotype: a moderate frame that branches well and produces evenly developed colas with a mix of density and airflow. But expect variation — roughly 1 in 4 plants will lean more strongly in one parental direction, which is part of what makes pheno-hunting this strain interesting. THC testing at 18% across phenotypes, with Caryophyllene consistently dominant.

Genetic Expression in the Grow Room

The dominant phenotype — which appears in roughly 70-75% of seeds — produces a balanced frame that takes to training intuitively. The branching pattern suggests hybrid vigor — aggressive enough to fill space without becoming unmanageable. Flower structure falls between dense and airy, which provides a good balance of bag appeal and mold resistance.

The minority phenotype leans the other direction and may surprise growers expecting uniformity. Flowering completes in 8-10 weeks across phenotypes. Yield: 400-500g/m² indoor, 400-600g/plant outdoor. Height: Short-Medium (2-3.5 ft). Rated intermediate — the phenotype variation adds a layer of interest without adding significant difficulty. Growing from regular seeds with autoflowering genetics.

Effects and Use

At 18% THC, Night Train delivers relaxed, happy, euphoric effects with a caryophyllene-influenced character. The onset is balanced — head and body arrive together and remain proportional throughout a 2-3 hour duration. This makes the strain adaptable to different situations depending on dose. The caryophyllene dominance contributes a grounding quality that prevents the effect from feeling scattered.

Terpene Profile

Dominant terpenes: Caryophyllene (primary), Limonene (secondary), Myrcene (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 Night Train

Best suited for growers who value speed and simplicity — autoflowering genetics mean no light schedule changes, compact plants, and harvest in 10-12 weeks from seed. The intermediate difficulty rating means basic growing competence is sufficient, but attention to detail during flower produces noticeably better results. Ships discreetly to all 50 US states with our germination guarantee.
