Neptune Kush Auto

Neptune Kush is a 10/90 sativa testing at 16% THC with a limonene-dominant terpene profile. At a practical level, this means a plant that stretches 40-60% after the flip and produces elongated colas with good light penetration through the canopy, finishing in 56 days seed to harvest. The Limonene/Pinene combination shapes both the aromatic profile and the effect character, this is not a one-dimensional strain.

Flowering time: 56 days seed to harvest from flip. Indoor yield at 600+ PPFD: 350-400 g/m2. Outdoor in full sun with 5+ gallon containers: 120-170 g/plant. Plant height indoors after training: 70-100 cm. Feed EC targets: 1.0-1.4 in veg, 1.4-1.8 in peak flower. pH range: 6.0-6.5 in soil, 5.8-6.2 in coco. Limonene production peaks when day/night temperature differential exceeds 10°F in the final two weeks, growers who drop nighttime temps to 62-65°F during this window report stronger aromatic development.

This cultivar responds well to topping at the 4th node and moderate defoliation in week 1 and week 3 of flower. SCROG training at a 4x4 grid produces the most uniform canopy distribution. Rated intermediate difficulty.

At 16% THC, Neptune Kush delivers happy, energetic, creative effects with a limonene-influenced character. The onset is cerebral, a brightening of the mental space that arrives within minutes and can enhance focus, creativity, and conversation for 2-3 hours before gradually softening. The body stays comfortable without heaviness. The limonene dominance keeps the mental space bright and slightly elevated even when the body relaxes.

Dominant terpenes: Limonene (primary), Pinene (secondary), Terpinolene (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.

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.
