What is the Mandarin Jack Herer strain?
Mandarin Jack Herer is an original QCS strain: Quebec Cannabis Seeds is its original breeder, and these are our own genetics, bred in Quebec by a grower with more than 35 years of experience.
Mandarin Jack Herer is a feminized autoflower from Quebec Cannabis Seeds, a cross of Mandarin Auto with Jack Herer Auto. Jack Herer is one of the best-known sativa-leaning names in cannabis; growers commonly describe it as a clear, pine-and-spice strain with a long-standing fan base. Mandarin supplies the orange-peel citrus and the fast, simple autoflower habit.
The result is pitched as a fast, simple, productive plant that flowers on its own schedule. Many seed companies sell strains named Jack Herer or Mandarin, and their breeding differs, so figures from elsewhere may not match. The numbers here are for the QCS version only.
One more point of honesty: for this cross, the QCS page gives no measured THC or yield figures. It says its ranges are based on the parent lines, so read them as estimates.
Is Mandarin Jack Herer indica or sativa?
QCS describes Mandarin Jack Herer as sativa-leaning, about 65 to 70% sativa in style. That fits the Jack Herer influence and the effects description: energized, happy and uplifting, with a relaxed finish rather than a heavy one.
If you are still weighing the two sides, our guide to what indica does to you is a useful contrast.
Mandarin Jack Herer smell and flavour
The tags are citrus, spice, earthy and pine, with lemony haze and incense notes. Think of a tangerine peel and a walk in a pine forest, with a faint incense warmth at the end. Jack Herer lines are commonly described as piney and spicy, and Mandarin lines as sweet citrus, so the profile hangs together.
Terpene balance changes with the plant, the grow and the cure. A slow dry helps preserve the brighter citrus notes.
Mandarin Jack Herer effects
QCS describes an energized, happy and uplifting effect with a relaxed finish. Consumers of Jack Herer-type plants commonly say they feel clear, creative and sociable, which is why many choose them for daytime. Effects vary by person and dose.
Start low and wait before taking more. We make no medical claims.
How strong is Mandarin Jack Herer? THC content
The QCS page gives about 18 to 24% THC, and says it is based on the parent lines rather than a measured figure for this cross. CBD is listed as low. That is a moderate-to-strong range, and a reasonable expectation rather than a promise. THC depends on the grow, the dry and the cure.
If you want a guaranteed-strong option, compare it with our cannabis seeds over 25% THC.
Growing Mandarin Jack Herer: flowering time and yield
As an autoflower, Mandarin Jack Herer does not need a light-cycle change. QCS lists about 9 to 11 weeks from seed to harvest indoors and August outdoors. Estimated yield is about 300 to 450 g/m² indoors in good conditions and 200 to 450 g per plant outdoors. The outdoor range is wide, so the page suggests planning around the lower figure. These are parent-line estimates, not measured results for this cross.
The plant is medium in height. The page cites roughly 69 to 110 cm, but that range comes from Jack Herer Auto examples, so allow a little extra headroom. Its advice for growing: sow straight into the final pot, keep the medium damp but not soaked at about 22 to 25 degrees C, use gentle training and good airflow, and judge harvest by trichomes rather than the calendar.
Autoflowers are forgiving but still need attention, and local rules should be checked before you grow. The chart below shows seed to harvest, not flowering time alone.
