Fire OG Seeds

Genetics & effects

Fire OG is a feminised, indica-leaning cultivar with commonly reported OG Kush × San Fernando Valley OG Kush genetics. Its profile is approximately 70% indica and 30% sativa, with listed THC levels of 18–24% and CBD levels of 0–2%. Genetic lineage and cannabinoid figures should be viewed as useful catalogue guidance rather than absolute values, as expression can vary between plants and growing environments.

Aromatic notes may combine earthy depth, fresh pine, pungent fuel and a sweet edge. Myrcene, limonene and beta-caryophyllene are among the terpenes associated with this profile. Individual experiences differ, but Fire OG is often described subjectively as relaxed, happy and euphoric, with a strong, settled character that may feel best suited to quieter moments.

Growing in Australia

Outback Seed Bank presents Fire OG as an intermediate-level option for growers familiar with canopy control, airflow and environmental monitoring. Its feminised format is intended to produce female plants, although natural variation remains possible. In Australia, outdoor planting is generally aligned with spring from September to November, subject to local temperatures, daylight and rainfall.

Hot, dry and temperate settings may suit this cultivar. In humid coastal or subtropical areas, allow generous spacing and maintain airflow to reduce the risk of mould around dense flowers. Always check the rules applying in your state or territory before obtaining or growing seeds.

Indoor

Indoors, Fire OG may reach up to 150 cm and usually needs around 9–10 weeks of flowering. Training and early canopy shaping can help manage vertical growth and improve light distribution. Keep humidity stable, provide regular air movement and inspect tightly packed flowers as they develop.

Under suitable conditions, listed indoor yields are up to 550 g/m². This figure is an estimate rather than an assured outcome; lighting, nutrition, root space, plant health and grower experience all influence final performance. Explore more options in the feminised seed collection.

Outdoor

Outdoor plants may grow up to 200 cm where warmth, direct sun and root space are available. A sunny, sheltered position can support branching while limiting exposure to strong wind. In wetter districts, select a location with rapid drainage and avoid crowding plants. Routine inspection is especially useful after rain or during periods of elevated humidity.

Listed outdoor yields are up to 600 g per plant in favourable conditions. Results vary with climate, seasonal timing, soil quality, pests and plant care. Its pine-green appearance may develop additional colour as nights cool late in the season.

Harvest

Australian outdoor harvest commonly falls between March and May. Rather than relying on a calendar date alone, assess flower maturity and local weather patterns. Indoors, plan for the 9–10 week flowering window, while allowing some variation between individual plants. Careful drying, steady airflow and controlled humidity can help preserve Fire OG’s earthy, pine, sweet and pungent qualities after harvest.
