About Alchemy Feminized
Alchemy is a 59/41 hybrid testing at 21% THC with a limonene-dominant terpene profile. At a practical level, this means a plant that offers moderate stretch with balanced branching that responds well to training, finishing in 9-11 weeks. The Limonene/Caryophyllene combination shapes both the aromatic profile and the effect character β this is not a one-dimensional strain.
Growing Parameters
Flowering time: 9-11 weeks from flip. Indoor yield at 600+ PPFD: 450-550g/mΒ². Outdoor in full sun with 5+ gallon containers: 350-500g/plant. Plant height indoors after training: Compact (2-3 ft). 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 10Β°F in the final two weeks β growers who drop nighttime temps to 62-65Β°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, Alchemy delivers relaxed, happy, euphoric effects with a limonene-influenced character. The onset is balanced β 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 limonene dominance keeps the mental space bright and slightly elevated even when the body relaxes.
Terpene Profile
Dominant terpenes: Limonene (primary), Caryophyllene (secondary), Linalool (tertiary). This combination produces an aroma profile that is immediately identifiable when the jar opens and translates well to both vaporization (best at 360-385Β°F) and combustion, though lower temperatures preserve the caryophyllene top notes that combustion destroys.
Who Should Grow Alchemy
Best suited for growers who want control over their plant size and harvest timing β 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.
