Hellfire OG Auto brings California OG character into a fast, compact autoflower. Expect dense, crystal-coated buds, a bold mix of spice and citrus, and a deeply relaxing finish. With reported THC levels of 24–30% and an 8–10 week life cycle, this indica-dominant variety pairs serious potency with a quick, rewarding grow.
Our breeders crossed Hellfire OG with Ruderalis to create a 70% indica, 30% sativa hybrid that flowers automatically. Its lineage traces back to California OG genetics, prized for rich flavor and resin production. The result is a sturdy plant with a compact stature of about 1 m and a fast, dependable cycle.
Crack open a ripe bud and the aroma rolls out in layers: earthy herbs, sharp citrus, warm spice, and a sweet finish. Look closer and you’ll find dense flowers with a frosty coat of resin. On the palate, citrus and earth mingle with herbal sweetness, pine, and a touch of sour fuel.
Hellfire OG Auto is known for a powerful, euphoric lift that gives way to deep physical relaxation. Its indica-heavy character makes it a fitting choice for unwinding in the evening. The reported potency is high, so approach it thoughtfully and give yourself time to settle into the experience.
Caryophyllene, myrcene, terpinolene, and alpha-pinene shape this cultivar’s distinctive aromatic profile. Its generous trichome coverage also makes it a compelling option for growers interested in resin-rich flower for extracts and concentrates. The calming reputation suits quiet evenings and laid-back downtime.
These are autoflowering seeds, so plants move into bloom without a change in light schedule. From germination to harvest, the cycle takes around 8–10 weeks. Grassfarmer backs every order with a germination guarantee, giving you added confidence from the start.
Start seeds in a quality, well-draining medium such as coco, peat, or a blend amended with perlite. Keep feeding appropriate to each growth stage, and avoid overloading young plants. Indoors, an 18/6 or 20/4 light schedule supports vigorous development; outdoors, choose a sunny site and time planting for favorable weather.
The plants stay compact and suit indoor gardens or smaller spaces. Hellfire OG Auto is described as moderately easy to grow, making it a welcoming option for newer cultivators. Maintain steady warmth, good airflow, and sensible humidity. Watch for pests, and avoid abrupt changes in growing conditions.
