About Double Bubble Feminized

Double Bubble is a 45/55 hybrid testing at 22% THC with a myrcene-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 Myrcene/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: 350-450g/m². Outdoor in full sun with 5+ gallon containers: 500-700g/plant. Plant height indoors after training: Tall (4-5 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. Myrcene 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.

What Users Report

Double Bubble at 22% THC produces relaxed, focused, calm sensations that users consistently describe as versatile enough to serve different purposes depending on dose and setting. Lower doses lean more cerebral and functional. Higher doses bring the body effect forward. The Myrcene/Limonene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other hybrids at similar THC levels.

Best suited for flexible use across the day — lighter doses for daytime function, heavier doses for evening relaxation.

Terpene Profile

Dominant terpenes: Myrcene (primary), Limonene (secondary), Pinene (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 Double Bubble

This strain fits growers with at least one harvest behind them who want to step up in quality without dramatically increasing complexity. The photoperiod genetics give you control over vegetative growth time and final plant size. Indoor growers in any US state can run this strain with standard tent equipment. Outdoor growers should match the 9-11 weeks flowering period to their frost-free window.
