The specs in one line: 18% THC, <2% CBD, 9-10 weeks flowering, 350g/m2 reported. Best indoor or outdoor. moderate grow.

Smell-first: crack a jar of this feminized sativa and the nose goes straight to ripe tropical fruit before a damp, earthy bass note pulls it back to earth. That tension carries into the effect—18% THC pushes a clear-headed, energetic headspace without the anxious edge some sativas bring. Pineapple Jack comes from Growers Lab Seeds' proprietary breeding program and leans heavily on Jack Herer's sativa structure, so expect stretch during the first weeks of flower. Budget the full 9–10 week window before harvest; rushing it shortens both yield and complexity. Indoors under a managed canopy, 350 g/m² is realistic at moderate skill—topping early and keeping humidity below 50% in late flower will make the difference. It runs well outdoors too, though Canadian growers in shorter-season zones (think most of BC interior, Alberta, Ontario north of the Shield) should start seeds by mid-May to finish before temperatures drop.

Best suited to growers comfortable with sativa stretch who want a daytime-leaning variety without chasing extreme potency numbers.

Genetics & Lineage

Pineapple Jack traces its genetics to Proprietary cross (Growers Lab Seeds). This sativa-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. 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 18%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Pineapple Jack delivers THC levels of 18%, 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, starting as a cerebral buzz that gradually expands.

Growing Pineapple Jack

Pineapple Jack 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 9-10 weeks with yields of 350g/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

Pineapple Jack features a earthy, fruity 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, Pineapple Jack 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.
