About Grapefruit Feminized
Grapefruit is a 30/70 sativa testing at 21% THC with a pinene-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 8-9 weeks. The Pinene/Limonene combination shapes both the aromatic profile and the effect character, this is not a one-dimensional strain.
Growing Parameters
Flowering time: 8-9 weeks from flip. Indoor yield at 600+ PPFD: 500 g/m2. Outdoor in full sun with 5+ gallon containers: 300 g/plant. Plant height indoors after training: 80-100 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. Pinene 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.
Effects and Use
At 21% THC, Grapefruit delivers energetic, happy, uplifted effects with a pinene-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 pinene dominance adds a clarity that many users describe as "functional".
Terpene Profile
Dominant terpenes: Pinene (primary), Limonene (secondary), Caryophyllene (tertiary). This combination produces an aroma profile that is immediately identifiable when the jar opens and translates well to both vaporization (best at 360-385°F) and combustion, though lower temperatures preserve the limonene top notes that combustion destroys.
Who Should Grow Grapefruit
Best suited for growers who want control over their plant size and harvest timing, photoperiod genetics let you veg as long as you want before triggering flower. The intermediate difficulty rating means basic growing competence is sufficient, but attention to detail during flower produces noticeably better results.
