Blackberry Kush Auto Seeds

Blackberry Kush Auto is a feminised autoflowering selection presented in the Outback Seed Bank catalogue. Combining Cream Caramel Auto with Purple Kush, it offers compact growth, dark colour potential and a sweet berry-led aroma. Its beginner-friendly format and short flowering period suit growers seeking a straightforward addition to an Australian garden or indoor setup.

Genetics & effects

This 80% indica and 20% sativa hybrid carries autoflowering genetics, so flowering begins according to plant maturity rather than a change in daylight hours. Listed THC levels are 15–19%, while CBD is listed at up to 0.5%. Individual results and experiences can vary.

Reported effects are subjective, but some consumers describe Blackberry Kush Auto as initially happy and powerful before settling into a deeply relaxed, sleepy feeling. Its flavour profile blends berry, citrus and ripe fruit with earthy Kush and lingering sweetness. Myrcene, caryophyllene and limonene are the prominent listed terpenes.

Growing in Australia

Its compact structure and adaptable climate profile make this variety relevant to hot, dry areas, temperate districts and cooler regions with short summers. Spring planting in Australia falls between September and November. Select a position with strong light and steady airflow, and avoid prolonged moisture around foliage and flowers to reduce mould risk.

As an autoflower, it generally benefits from minimal disruption and a consistent routine. Use a free-draining medium, allow the root zone to breathe and make gradual adjustments rather than abrupt changes. Browse more autoflower seeds with similarly convenient growth cycles.

Indoor

Indoors, Blackberry Kush Auto may reach up to 110 cm, depending on container size, lighting and overall conditions. Its relatively modest height can fit smaller rooms or tents, while gentle canopy positioning may help keep light exposure even. Avoid heavy plant work once flowering is established.

The listed indoor yield is up to 450 g/m². This figure is a reference rather than an assured outcome, as light quality, airflow, nutrition, environment and grower experience all influence performance. Good ventilation becomes especially important as flowers gain density.

Outdoor

Outdoor plants may also grow up to 110 cm and are listed to produce up to 300 g per plant. Choose an open, sunny location protected from severe wind and persistent rain. In humid districts, extra spacing and regular observation can help maintain airflow. The variety’s compact form may appeal to growers who prefer a less expansive garden plant.

Harvest

Flowering is listed at approximately eight to nine weeks. For spring-planted Australian outdoor crops, the broader harvest period generally falls from March to May, although autoflower timing depends more directly on each plant’s age and growing conditions. Watch flower maturity rather than relying only on the calendar.

Berry sweetness, citrus brightness and earthy Kush character may become more pronounced near maturity. Purple or dark colour can appear in some plants, but expression varies with phenotype and environment. Careful handling at harvest helps retain the aromatic profile that makes this compact auto a favourite among fans of fruity, indica-dominant varieties.
