Alien OG Seeds

Genetics & effects

Alien OG is a feminised, balanced photoperiod hybrid combining Alien Kush with Tahoe OG. Its 50% sativa and 50% indica profile brings together vigorous growth, substantial flower formation and a layered aroma. Catalogue figures place THC at 20–28% and CBD at 0–1%, so this selection is best suited to experienced consumers who understand their own preferences.

Experiences may feel euphoric, uplifting and happy, sometimes developing into a cerebral, energetic or talkative mood. Some people also report a stronger appetite. Effects remain subjective and can differ with the individual, setting and final flower quality.

The terpene profile features myrcene, limonene, caryophyllene and pinene. Expect pungent pine and lemon over earthy, sweet and citrus notes, with a skunky edge that becomes more noticeable as flowers mature. It may appeal to growers who count classic OG aromas among their favourite profiles.

Growing in Australia

Presented in the Outback Seed Bank catalogue, Alien OG is rated for intermediate growers and performs best with consistent attention. Its preferred climates are hot, dry and temperate, making airflow, moisture control and seasonal timing important across Australia. Photoperiod plants begin flowering as daylight hours shorten, so plan the full cycle around local conditions.

For an outdoor run, spring planting generally falls between September and November. Select a bright position with good air movement and free-draining soil. In humid or coastal areas, allow generous spacing and inspect dense flowers regularly to reduce the risk of mould. Explore more feminised seeds or browse the photoperiod seed collection.

Indoor

Indoors, Alien OG can reach up to 160 cm. Training early in vegetative growth can help create an even canopy and keep vertical stretch manageable. A stable light schedule, responsive ventilation and balanced feeding support steady development. Avoid persistently damp growing media, and allow suitable drying between irrigation events.

• Flowering time: approximately 8–10 weeks
• Indoor height: up to 160 cm
• Indoor yield: up to 550 g/m² under favourable conditions

Carbon filtration may be useful where discretion matters, as the pine, citrus, earth and skunk aromas can become pronounced late in flowering. Check branches as flowers gain weight and add support where needed.

Outdoor

Outdoors, plants may reach up to 200 cm and have the potential to produce up to 600 g per plant in favourable conditions. Results vary with sunlight, root space, weather, nutrition and grower experience. Hot, dry locations suit the variety well, while temperate regions benefit from a sunny site protected from prolonged rain and harsh wind.

Keep the area around each plant open and tidy to maintain airflow. Monitor weather as autumn approaches, especially when cool nights and rainfall coincide. Container growers can move plants into shelter during severe conditions, provided light and ventilation remain adequate.

Harvest

Australian outdoor harvest commonly falls between March and May, depending on planting time, latitude and seasonal conditions. Assess flower maturity across several sites on the plant rather than relying on a calendar date alone. Indoor crops are usually ready after the listed 8–10 week flowering period.

At harvest, handle aromatic flowers gently and maintain a clean, shaded environment with steady airflow. Careful post-harvest drying helps retain the distinctive lemon, pine, sweet earth and pungent citrus profile. Final height, timing, colour, aroma and yield will vary between plants and growing environments.
