How to grow Colombian Jack
Seb's take
Nebula and Black Jack combine for a 70% sativa that starts with hybrid steadiness before stretching taller as it goes, backed by an award-winning 28% THC. Lime, grapefruit and citrus on the nose; the high opens creative and social, then a relaxing body note pulls it back to earth. Give her the headroom, especially outdoors.

Flowering runs the standard 10 weeks — no surprises, which in this business is a compliment. The flowering stage guide covers what each of those weeks should look like.
