About Rockstar Feminized

Rockstar is a 50/50 hybrid testing at 18% 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 9-11 weeks. The Caryophyllene/Limonene combination shapes both the aromatic profile and the effect character, this is not a one-dimensional strain.

Growing Parameters

Flowering time: 9-11 weeks from flip. Indoor yield at 600+ PPFD: 400-500g/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. 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 18% THC, Rockstar delivers happy, relaxed, sleepy 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 nose that develops complexity through the cure, expect the primary caryophyllene character to emerge first, with limonene and myrcene notes adding layers over 3-4 weeks in jars.

Who Should Grow Rockstar

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. Ships discreetly to all 50 US states with our germination guarantee.
