About Magnum Auto

Magnum is a 49/51 hybrid testing at 15% THC with a caryophyllene-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 approximately 85 days (seed to harvest). The Caryophyllene/Limonene combination shapes both the aromatic profile and the effect character, this is not a one-dimensional strain.

Growing Parameters

Flowering time: approximately 85 days (seed to harvest) from flip. Indoor yield at 600+ PPFD: 550-600 g/m2. Outdoor in full sun with 5+ gallon containers: 100-250 g/plant. Plant height indoors after training: Up to 150 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. Caryophyllene production peaks when day/night temperature differential exceeds 10Β°F in the final two weeks, 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 15% THC, Magnum delivers focused, calm 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 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 limonene top notes that combustion destroys.

Who Should Grow Magnum

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.
