Lineage: Jack Herer ancestry bred into an autoflowering format by Growers Lab Seeds, producing a plant that finishes in 8–9 weeks without sacrificing much of what made the original famous. At 20% THC, it sits comfortably in the upper range for autos, and indoor growers regularly pull 450g/m² when light schedules and feeding are dialed. The terpene profile leans pine-forward with fruity and sweet notes underneath — cleaner on the exhale than a lot of high-THC autos that skew gassy.

Moderate difficulty means first-time auto growers may hit a learning curve, but anyone who's run a couple of photoperiod cycles will adapt quickly. It performs in both indoor and outdoor setups, staying compact enough for tent grows without sacrificing canopy output. If you're chasing a daytime-leaning auto with enough yield to justify the run, this one is worth the grow slot.

Genetics & Lineage

Super Jack Auto traces its genetics to Proprietary cross (Growers Lab Seeds).

Bred by Growers Lab Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 20%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Super Jack Auto delivers THC levels of 20%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes with a balanced head-and-body experience that evolves over time.

Growing Super Jack Auto

Super Jack Auto is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 8-9 weeks with yields of 450g/m2. Plants typically reach 100-160cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

Super Jack Auto features a fruity, pine, sweet terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Super Jack Auto is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
