QuadJacks

Cannabis Strain by Sin City Seeds

Introduction
QuadJacks from Sin City Seeds combines four distinct genetics in a mostly-sativa expression finishing in 69 days. Sin City built their reputation on creating complex multi-parent crosses, often blending elite clone-onlys with proven breeding stock. The "Quad" prefix indicates four-way genetics, while "Jacks" suggests Jack Herer or Jack's Cleaner involvement—both known for clear-headed sativa effects and citrus-pine terpenes.

Lineage
The extended lineage creates phenotypic variation across seeds, with different expressions emphasizing various parent traits. Sin City's breeding methodology involved F1 crosses for hybrid vigor rather than stabilized lines, meaning growers should expect diversity and select preferred phenotypes. The 69-day flowering sits in upper-moderate territory, allowing proper sativa development without pushing into landrace timelines.

Terpenes
Terpene profiles in Jack-derived genetics typically feature terpinolene, limonene, and pinene—creating citrus, pine, and floral complexity. QuadJacks maintains this framework while potentially adding complexity from the additional parents. Growers report bright, clean aromatics—lemon and pine forward, with herbal undertones that develop during cure.

Growth
Cultivation requires sativa management: height control, adequate space, training for stretch. The 69-day window works for indoor operations and outdoor growers in extended-season climates. Structure follows sativa patterns: tall potential, open branching, longer internodes. Yields can be substantial with proper space and time.

Effects
Effects align with functional sativa territory: mental clarity, creative energy, sustained focus without sedation. Duration tends longer with quality sativas (3-4 hours). Common uses include daytime productivity, creative work, social engagement.

Documentation
Sin City Seeds released numerous genetics before eventually closing operations, making availability dependent on preserved stock.
