STRNG Seeds – Jack Herer

Jack Herer blends rich history, uplifting character, and a complex flavor profile into one well-balanced plant. It’s known for its bright aroma, sturdy structure, and clear-headed personality that appeals to a wide range of growers.

Expect a spicy-sweet blend of pine, citrus peel, and subtle herbs. The taste is fresh and slightly peppery, with a crisp finish that lingers on the palate.

The scent builds into a strong mix of lemon zest, pine, and faint clove by week 6, becoming sharper and more herbal toward harvest.

It’s a favorite among growers who enjoy uplifting, citrus-pine aromas and classic, old-school genetics with modern stability.

Buds are medium-dense with a forest green base and bright orange pistils. A fine dusting of trichomes gives them a frosty appearance once cured.

It generally reaches 100–140 cm and can stretch significantly in flower. Early training is recommended to control its sativa-leaning height.

The buds are long and slightly open with solid resin coverage — classic of sativa-dominant hybrids — and fill out well with proper lighting.

Our feminized seeds remove the guesswork, ensuring that every plant produces flower — ideal for maximizing canopy efficiency and reducing wasted time and space.

Full-spectrum LED or HPS lighting works well. This strain responds favorably to high light intensity, especially during weeks 4–8 of flower.

Indoors, yields typically range from 450–550g/m² under optimal conditions. Outdoors, plants can yield significantly more with proper sun, feeding, and airflow.

Yes. Its fresh, piney citrus aroma and long-standing reputation make it ideal for flavor-driven growers who want clarity and brightness over sweetness.

STRNG selected phenos with sharper citrus-pepper aroma and tighter structure, optimizing their version for indoor growers who want clarity, height control, and consistent bud formation.

It thrives in sunny, temperate regions and benefits from long seasons. Outdoors, it may grow taller than indoors and deliver larger yields with bright, fresh aroma.

Outdoors, Jack Herer can reach 180–220 cm depending on conditions. It forms a tall, open structure with strong central growth and solid branching.

It’s moderately easy to grow. While it stretches and can be sensitive to overfeeding, it’s highly resilient overall and responds well to basic training.

Its looser bud structure makes it more tolerant than compact indicas, but humidity should still be kept below 50% in flower to avoid moisture-related risks.

Flowering takes around 9–10 weeks indoors. Some phenotypes may finish earlier, while others lean slightly longer depending on setup and training.

Topping, LST, and SCROG techniques all work well. Because of its stretch and upright growth, early structure management helps maximize light use and yield.

It prefers balanced feeding and slightly lower nitrogen in late flower. Overfeeding can mute its aroma, so light adjustments during bloom help preserve terpene clarity.
