- Mango (42% of reported flavors)
Jack the Ripper cuts straight to the zest. Sharp lemon-cleaner funk leads the original Subcool release, followed by sweet mango, pine, and a lingering hashy finish. Its reputation rests on generous resin and an assertive cerebral rush, with enough citrus bite to leave a lasting impression.
Origin 1: Subcool developed the original under TGA Genetics, crossing Jack’s Cleaner with a Space Queen male known as Space Dude. The goal was to explore a new outcross of the prized mother. The resulting offspring retained her forceful lemon character while introducing sweeter mango notes and a smoother flavor.
Later generations continue that lineage. The F2 release from 2 Guns and a Guy Seed Company pairs two plants from the original F1 generation, making it a continuation of Subcool’s cross. Its selected parents emphasize pronounced lemon aromas, with green, pink, and purple coloration described in the breeder’s plants.
Origin 2: Zambeza’s Jack the Ripper Autoflowering comes from Jack Herer crossed with ruderalis. This is a separate genetic pairing sold under a similar name. Zambeza describes sweet, sour, and bitter flavors with happy, uplifting effects; those details belong to its autoflowering release.
The original’s flowers are notably resinous, often described as pointed or triangular. Subcool noted substantial stretch and colas that swell late in flowering, although shorter selections also occur. Lemon dominates the aroma, with tropical sweetness, pine, and hash adding depth beneath that sharp first impression.
People who’ve hit these cuts describe energetic euphoria, creative momentum, and an intense cerebral lift. Some find it focused; others describe a more scattered, trippy experience. Subcool also noted increased appetite and a pronounced comedown, so its lively opening does not guarantee an equally lively finish.
Subcool lists the original photoperiod release for indoor and outdoor cultivation, with approximately 8–10 weeks of flowering and medium yields. Its characteristic stretch and late-swelling colas distinguish it from descriptions of uniformly short, fast-finishing plants.
The 2 Guns and a Guy F2 release is offered as regular seed, with approximately nine weeks of flowering and a medium-to-large stature. Its breeder likewise notes some stretch.
Zambeza’s distinct autoflowering release is listed at 60–70 days from germination to harvest, rather than 60–70 days of flowering. The breeder describes plants around 60–90 cm tall indoors. Older listings under Jack Herer Automatic give different timing, so those specifications should remain tied to their particular release.
