Strain Description:

    Jack Plant delivers the classic uplifting spirit of Jack Herer with a slightly reduced flowering time, thanks to a subtle Indica influence. This results in a powerful yet refined Sativa experience that remains clear-headed, energising and long-lasting. Buds form long, resinous colas typical of Sativa hybrids, while the flavour leans towards a pleasing sweetness. Known for its robustness and mildew resistance, Jack Plant is a strong choice for growers in variable climates who still want large, high-quality harvests.
  
Growing Information:

    This strain adapts well to both indoor and outdoor cultivation. Indoors, Jack Plant remains manageable if trained correctly, responding well to topping, LST and SCROG methods. Outdoors, however, is where it truly excels—reaching between 3 and 5 metres in height and producing exceptionally large yields under full sun. Its natural resistance to mildew makes it even more reliable in humid regions. With a bloom time of 9–10 weeks, Jack Plant offers a fast turnaround for a Sativa-dominant strain of this calibre.
  
Strain Flavour and Aromas:

    Jack Plant features a sweet, smooth profile with gentle herbal notes typical of Jack Herer descendants. The sweetness complements its energetic effect, making the flavour as uplifting as the experience itself. The terpene expression is clean, refreshing and lightly floral, making it appealing for daytime use.
  
Strain Lineage:

    Derived from careful selection of Jack Herer genetics, Jack Plant carries the legacy of one of the most iconic Sativa-dominant strains in modern cannabis breeding. Jack Herer passes down its energising cerebral effect, resin production and aromatic complexity, while the slight Indica addition shortens flowering time and enhances sweetness.
  
Strain Summary:

    Jack Plant by Advanced Seeds is a high-performing, mostly Sativa feminised strain delivering sweet flavours, an energising effect and impressive growth potential—especially outdoors, where it can reach up to 5 metres tall. With 20% THC, a 9–10 week bloom and yields of 450–500 g/m², it is an exceptional choice for growers wanting a vigorous, reliable Sativa with big outdoor production and classic Jack Herer quality.
