K45 arrives from DJ Short's Old World Genetics library as a collaboration with Second Generation Genetics, a line-bred Blue-Line selection refined beyond F4. In the garden it leans sativa, stacking long, pointed spear tops and branching freely, while staying disciplined enough for training. Expect a later finish than many blues, most phenotypes ripen in about 60-67 days, rewarding patience with moderate-to-high yields. The bouquet is unmistakably Blue-family: musky citrus over kush-berry sweetness, laced with cedary wood and a lilac floral accent; the palate tracks the nose, bright and resinous, with a berry-citrus front and a dry, woodsy fade. Effects land in a classic DJ Short register: potent yet composed, with a narcotic body hum under an energizing, daydreaming headspace that lifts mood without turning racy. Official lab numbers are scarce, but potency and terpene intensity align with its heritage. K45 is produced as regular photoperiod seed from the in-house cross F4 K-FK/K45 x F4 K-FK/K45, preserving genetic fidelity while offering room for selection. Growers should plan for height and airflow; the sativa frame responds well to topping, LST, and SCROG. Expect vigorous rooting and strong stem development from seed. For collectors of heirloom Blue genetics, K45 reads like a fresh chapter, modernized structure and finish, unmistakably authored by DJ Short.
