Aliens JackD Up from Sin City Seeds jolts the classic Alien lineage with a Jack-hued spark. Built by pairing a strongly Alien Tech-leaning Sour Alien mother with a Sour Jack male, this sativa-dominant hybrid (60% sativa/40% indica) was selected for towering resin and a brighter, more productive structure than its Sour Alien parent. In the garden it sets an assertive vertical stance, with tall phenos that often appreciate support, and finishes in roughly 60-70 days. Expect average to above-average yields of icy colas wearing swollen trichomes and frosted fans. The nose marries sour-citrus and hash with jet-fuel and faint fruit, while the taste runs tangy-sour and diesel over a sweet, fruity undercurrent. Effects tilt upbeat and clear: energetic, uplifted, and happy, with the usual dry mouth/dry eyes and, in overenthusiastic moments, a touch of anxious edge. The chemotype is THC-forward with very low CBD, delivering a bright, buzzy ride without couchbound heaviness. Hashmakers prize its trichome coverage for bubble or sift, and cultivators will note a cooperative, scrog-friendly frame that outperforms the original Sour Alien in density and stacking. Credit to Sin City Seeds for dialing this extraterrestrial homage; Aliens JackD Up feels exactly like its name suggests - Sour Alien and Sour Jack, turned up and tuned for modern gardens.
