Quick read: 18-25% THC, 120-200cm mature height, 10-12 weeks bloom. Genetics: Jack Herer Feminised (Seedsman genetics). Difficulty: moderate.

Seedsman lists this at $68.58 — the upper end of the comparison range (up to $60.75). Pack options: 3-seed at $68.58, 5-seed at $114.30, plus larger sizes.

Lineage: the original Jack Herer breeding work leaned on Haze, Northern Lights #5, and Shiva Skunk — and Seedsman's feminized cut keeps that sativa backbone intact. Indoor growers running this under 600W HPS have pulled close to 600g/m², though that upper end asks for some canopy management skill; Seedsman rates it moderate difficulty for a reason. Flowering stretches 10 to 12 weeks, longer than most shelf-fillers, but the payoff is a sharp pine-and-earth nose that doesn't fade after cure. THC tests typically land in the 18–22% range in practical grows, occasionally touching 25% in dialed-in environments. The effect skews clear-headed and motivating rather than sedating, which matters if you're growing for daytime use or creative work.

Works indoors or out, but outdoor growers in northern climates should watch that 10–12 week flower window against their first frost date.

THC Level & Potency

Jack Herer Feminised delivers THC levels of 18-25%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies.

Growing Jack Herer Feminised

Jack Herer Feminised 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 10-12 weeks with yields of 500-650g/m². Plants typically reach 120-200cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. 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 the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Jack Herer Feminised features a pine, earthy terpene profile that develops complexity throughout the flowering cycle. Sharp forest and resin notes create a fresh, invigorating flavor with earthy depth. 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, Jack Herer Feminised is commonly reported to help with depression, fatigue, lack of motivation, and ADHD symptoms. The uplifting, focusing effects make it popular among medical users seeking daytime functionality. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
