OG Kush Seeds

The Outback Seed Bank catalogue presents OG Kush as a feminised, THC-dominant option for growers with some previous experience. Its compact-to-medium indoor structure, robust aroma and relatively short flowering window make it a favourite among cultivators seeking classic Kush character. Reported THC levels range from 19–26%, while CBD is typically 0–0.5%. Figures are indicative, as environment and phenotype can influence each plant.

Genetics & effects

OG Kush is commonly reported as ChemDawg × Lemon Thai × Pakistani, although its exact lineage remains disputed. The profile is approximately 45% sativa and 55% indica, offering a slight indica lean without an especially one-sided growth pattern.

Aromas and flavours may combine earthy pine, woody spice and fresh citrus. Myrcene, limonene and beta-caryophyllene are commonly associated with this profile. Individual experiences vary, but some people describe the effects as initially uplifting, happy or euphoric, followed by a more relaxed and occasionally sleepy feeling. Potency and personal response can differ considerably.

Growing in Australia

OG Kush is considered an intermediate-level cultivar suited to hot, dry and temperate Australian conditions. Outdoor planting generally aligns with southern-hemisphere spring, from September to November. In warmer regions, afternoon shade and consistent root-zone moisture may help during intense heat. In temperate areas, selecting a sunny position with airflow can reduce the risk of excess humidity and mould as autumn approaches.

Use a free-draining medium and avoid prolonged saturation around the roots. This variety can respond well to attentive canopy management, though growers should allow recovery time after major adjustments.

Indoor

Indoors, OG Kush typically reaches 90–160 cm and flowers in about 8–9 weeks. Its moderate stretch can be managed with low-stress training, topping or a screen, depending on the available space and grower preference. Good air exchange is useful because dense floral growth may retain humidity.

• Flowering time: approximately 8–9 weeks
• Indoor height: around 90–160 cm
• Indicative indoor yield: 350–475 g/m²

Earthy and pine-forward aromas may become pronounced during flowering, so suitable ventilation can be helpful in enclosed spaces. Balanced nutrition and steady environmental conditions are preferable to abrupt changes.

Outdoor

Outdoor plants may reach 150–200 cm where root space, sunlight and conditions are favourable. A sheltered but well-ventilated site can support branching while limiting exposure to strong winds. In humid districts, spacing branches and checking dense flower sites regularly may reduce mould risk.

• Preferred climates: hot, dry or temperate
• Outdoor height: around 150–200 cm
• Indicative outdoor yield: 400–550 g per plant

Harvest

Australian outdoor harvest generally falls between March and May, depending on planting time, latitude, phenotype and seasonal weather. Rather than relying on the calendar alone, assess flower maturity closely and consider upcoming rain or humidity. Indoor plants are usually ready after their 8–9 week flowering period. Yield, cannabinoid content, colour and aroma will vary with environment and cultivation choices.
