Meet Jack Herer x White Widow Auto, a Sativa-leaning autoflower built for bright, energetic effects and frosty, resin-rich buds. Expect a lively citrus-fruit profile, a quick 10–12-week life cycle, and impressive yield potential in a compact, hardy plant.

Our breeders crossed Jack Herer and White Widow with Ruderalis to create this easygoing autoflower. Its heritage brings together the Haze, Skunk, and Northern Lights roots of Jack Herer with the Brazilian Sativa and South Indian Indica lineage associated with White Widow. The result is a balanced genetic mix of 60% Sativa and 40% Indica.

Crack open a ripe bud and enjoy a vivid blend of citrus, earth, and ripe fruit. Dense flowers shine with a thick coat of resinous trichomes, while the smooth, flavorful smoke brings a fresh, lively finish.

With a reported THC range of 20–24%, Jack Herer x White Widow Auto delivers a potent, uplifting experience. Expect a euphoric mood lift and an energetic, clear-headed feel, with a gentle note of relaxation in the background.

Alpha-pinene and beta-pinene bring bright, crisp aromatic notes, while caryophyllene and myrcene add warm spice and earthy depth. The lively profile suits daytime sessions, creative projects, and social moments. Its generous resin production also makes the strain a compelling choice for concentrate enthusiasts.

These autoflowering seeds flower with age, without a change to the light schedule. The full cycle takes around 10–12 weeks from germination to harvest. Germination is guaranteed, giving you added confidence as you begin your grow.

Give seedlings a steady start with quality substrate, gentle watering, and suitable nutrients. Coco, peat, or a well-aerated mix with perlite can support healthy root development. Indoors, growers commonly use an 18/6 or 20/4 light schedule; outdoors, choose a sunny location and a season with comfortable temperatures.

Expect a sturdy plant that can reach around 1.5 m in favorable conditions. Its robust growth and autoflowering nature make it a welcoming option for newer growers. Maintain good airflow, watch for pests, and keep conditions warm and temperate as the plant develops.

As flowering progresses, the branches fill with dense, resin-coated buds and a pungent citrus-earth aroma. Harvest arrives in about 10–12 weeks. Reported yields reach 450–550 g/m² indoors and 100–200 g per plant outdoors, with results shaped by growing conditions and care.
