Jack Herer Fast Seeds
Price range: $58.50 through $255.00
Jack Herer Fast Seeds are a fast-flowering photoperiod interpretation of the Jack Herer cultivar family, whose core genetics are commonly associated with Haze × Northern Lights #5 × Shiva Skunk. The fast version is intended to retain Jack Herer’s tall, branchy structure, resin production, and citrus-pine-spice aroma while shortening the bloom period. Because fast versions can be produced through different breeding routes, the exact added fast-flowering ancestry should not be treated as universal.
- Lineage: Jack Herer-family genetics (Haze × Northern Lights #5 × Shiva Skunk) selected or crossed for faster photoperiod flowering
- Growth type: Sativa-leaning fast photoperiod hybrid
- Plant structure: Medium-tall to tall with long lateral branches and an open canopy
- Stretch: Moderate to high
- Indoor flowering: Typically about 6–8 weeks, with many fast selections finishing around 7–8 weeks
- Outdoor harvest: Typically September in the Northern Hemisphere, with some phenotypes extending into early October
- Flower structure: Elongated, resin-coated clusters with good calyx development
- Resin production: High
- Colour: Bright green with orange pistils; golden or amber tones may appear near maturity
- Aroma: Lemon, citrus, pine, herbs, spice, and light sweetness
- Best suited for: Growers wanting Jack Herer-style vigor with a materially earlier photoperiod finish
Jack Herer Fast retains substantial vertical energy, so indoor growers should still plan for height management even though the flowering period is shorter. Topping, low-stress training, or a screen can help spread the long side branches across the canopy and keep the tops within an even light zone.
Indoors, a practical planning range is approximately 42–56 days after the switch to 12/12, with many fast expressions finishing closer to seven or eight weeks. The fast trait shortens maturation but does not make the plant an autoflower; flowering is still controlled by the photoperiod.
Outdoors, the earlier finish is particularly useful in climates where October weather becomes unreliable. A practical Northern Hemisphere target is September, although some phenotypes may continue into the first part of October depending on latitude and seasonal conditions.
The aromatic profile commonly combines bright lemon and citrus with pine, herbal, spicy, and lightly sweet notes. Jack Herer Fast Seeds are best suited to growers looking for sativa-leaning structure and aroma with a substantially shortened photoperiod bloom.
