About Lemon Jack

Lemon Jack descends from Jack Herer x Lemon Skunk. The cross emphasises lemon terpenes and a clear cerebral effect.

Growing Lemon Jack is intermediate in difficulty and benefits from steady conditions in a mild southern growing climate in Down. It tolerates minor mistakes but needs regular pruning and attention to humidity.
Flowering usually takes eight to ten weeks under good conditions. Outdoor plants in a favourable season often finish toward the earlier end of that range.
Yields are medium to high when plants are trained and fed properly. Indoor growers can expect around 400–500 g/m2 while outdoor specimens yield well in fertile soil.
Plants are typically medium-tall with an open, branching structure. They form long colas suited to SCROG or LST techniques.
Lemon Jack performs well both indoors and outdoors in Down when humidity is managed. Indoor grows allow precise control while outdoor plants make the most of the mild season in Down.
In Down's mild southern growing climate Lemon Jack flowers reliably with reduced frost risk. Growers should still watch for late-season rain and fungal pressure.
Effects are uplifting and clear-headed with a warm, social energy. The high sharpens focus and eases mild tension without heavy sedation.
Flavours are citrus-forward with bright lemon zest over pine and a light earthy base. The aftertaste carries a subtle herbal spice.
