Black Jack Auto packs Jack Herer’s bright, creative lift into a quick, compact autoflower. Expect a vivid incense-and-sweet profile, resin-rich flowers, and a lively yet balanced character. With 17%–19% THC and a full cycle of just 8–10 weeks, this sativa-leaning hybrid brings standout genetics to a fast, rewarding grow.
Our breeders created Black Jack Auto from Jack Herer and Black Domina, then added Ruderalis genetics for automatic flowering. Jack Herer contributes its celebrated sativa spark, while Black Domina brings deep resin and composed indica character. The result is a European-bred hybrid with a 55% sativa and 45% indica balance.
The aroma opens with spicy pine and sandalwood incense, then deepens into earthy, sweet notes with a sharp hint of sour lemon. Its flavor follows through with smooth incense and sweetness. Dense, hard buds develop a crystalline coat of trichomes that gives each flower a striking, resinous finish.
At 17%–19% THC, Black Jack Auto delivers a cheerful cerebral lift with an energetic, euphoric edge. Creative focus comes forward, while Black Domina genetics add comfortable physical relaxation. The effect feels bright and balanced, making this a compelling choice for daytime enjoyment.
Terpinolene leads with fresh herbal brightness, joined by woody nerolidol, warm clove-like eugenol, and crisp alpha-pinene. Supporting terpenes add pine, citrus, spice, and sweetness to the layered incense profile. This expressive combination suits creative sessions and daytime downtime, with the relaxing character also appealing to those seeking a calmer end to a busy day.
These feminized autoflowering seeds flower without a change to the light schedule, making Black Jack Auto a straightforward option for newer growers. Expect seed to harvest in around 8–10 weeks, with a compact height near 1 m. Grassfarmer guarantees germination, so you can start with confidence.
Give seedlings a quality, well-draining medium such as coco, peat, or a suitable mix with perlite. Autoflowers move quickly through each stage, so keep conditions steady and avoid stressing young plants. Indoors, an 18/6 or 20/4 light schedule supports vigorous development. Outdoors, choose a warm, sunny spot and time planting for the start of a favorable season.
Black Jack Auto grows into a sturdy plant with a strong central stem and well-supported side branches. It suits indoor and outdoor gardens and performs best with ample light, clean airflow, and balanced nutrition through seedling, vegetative, and flowering stages. Aim for warm conditions around 20–25°C, keep humidity in check, and stay alert to pests.
The fast cycle makes this variety a practical pick for growers seeking a timely harvest. Indoor yields can reach 400–550 g/m², while outdoor plants can produce up to 700 g each in favorable conditions. Its heavy trichome coverage also makes the harvest especially appealing for resin-focused projects.
Choose Black Jack Auto for a quick crop, a vivid incense-and-pine bouquet, and a spirited, balanced effect. Grassfarmer offers premium genetics in small and bulk quantities, with fast, discreet shipping and guaranteed delivery across the USA, Canada, the European Union, and the U.K. Add this energetic classic to your garden and enjoy a standout harvest on an autoflower’s schedule.
