Cannabis Strain by Sweet Seeds

Introduction
Black Jack Auto from Sweet Seeds brings the classic Black Jack genetics—a celebrated cross of Black Domina and Jack Herer—into the autoflowering format, completing the full seed-to-harvest cycle in approximately 63 days. This Spanish seed company's autoflowering expertise makes the Jack Herer sativa experience accessible without photoperiod management.

Lineage
**Genetic Lineage** Sweet Seeds has developed one of the cannabis world's most respected autoflowering catalogs through years of dedicated ruderalis genetics work. Black Jack represents the cross of Black Domina—the legendary four-way pure indica of Northern Lights, Ortega Indica, Hash Plant, and Afghani SA—with Jack Herer, the celebrated sativa-dominant variety (Northern Lights #5 × Shiva Skunk × Haze hybrid) named after the cannabis activist and author. This parent cross produces a variety where Jack Herer's cerebral, creative sativa character is grounded by Black Domina's physical indica depth. The autoflowering adaptation incorporates ruderalis genetics for photoperiod independence while maintaining the hybrid's balanced characteristics.

Terpenes
**Terpene Profile** Black Jack Auto's aromatic profile bridges Black Domina's deep, earthy indica character with Jack Herer's distinctive spicy-piney complexity. Black Domina contributes heavy myrcene earthiness, beta-caryophyllene spice, and Hash Plant's resinous depth. Jack Herer adds the characteristic piney, spicy, woody complexity—terpinolene brightness, pinene clarity—that has made Jack Herer-descended varieties famous for their clean, cerebral aromatic character. Sweet Seeds' autoflowering genetics preserve these aromatics within the 63-day rapid cycle.

Growth
**Growth Characteristics** Black Jack Auto completes seed-to-harvest in approximately 63 days—one of Sweet Seeds' faster autoflowering completions, making it practical for continuous growing schedules and northern outdoor seasons. Feminized autoflowering format eliminates both photoperiod dependence and sexing requirements. Sweet Seeds' extensive autoflowering expertise ensures genetic quality is maintained through the ruderalis adaptation.

Effects
**Reported Effects & Experience** Black Jack genetics balance Jack Herer's renowned cerebral, energizing, creative stimulation with Black Domina's deep physical relaxation—creating a variety that delivers both mental engagement and body comfort. Sweet Seeds' autoflowering version maintains this balanced effect profile, making the classic Black Jack experience accessible in a rapid, convenient format for cultivators across diverse environments.
