Blackberry Kush Auto Seeds

Blackberry Kush Auto is a compact, feminised autoflower presented in the Kiwi Seed Bank catalogue. Its indica-dominant profile, colourful potential and straightforward schedule make it an approachable choice for growers seeking a smaller plant with rich fruit-and-Kush character.

Genetics & effects

This autoflowering hybrid combines Cream Caramel Auto × Purple Kush, with a profile described as approximately 80% indica and 20% sativa. Plants may express broad foliage, close internodal spacing and deep green to purple colour, especially when night temperatures become moderately cooler without stressing growth.

THC is listed at 15–19%, while CBD is listed at up to 0.5%. Experiences vary by person and setting, but users often subjectively describe the effects as initially happy and powerful, followed by a deeply relaxed or sleepy feeling. Aromas and flavours may include ripe berries, citrus, sweet fruit, earth and classic Kush notes. Myrcene, caryophyllene and limonene are among the associated terpenes.

Growing in New Zealand

As an autoflower, Blackberry Kush Auto begins flowering according to age rather than a major change in daylight. This can simplify scheduling in New Zealand, although strong light, stable conditions and attentive watering still matter. Its compact stature and beginner-friendly growth pattern suit hot, dry areas, temperate districts and cooler regions with short summers.

For outdoor seasonal cultivation, spring planting generally falls between September and November. In colder districts, waiting for settled conditions may reduce risk from late frosts. Choose a sunny, sheltered position with free-draining soil and steady airflow. Local conditions differ, so growers should check the rules that apply in their location before starting.

Indoor

Indoors, plants are listed to reach up to 110 cm. A light, well-aerated growing medium helps roots access oxygen, while restrained feeding may suit the naturally quick autoflower schedule. Avoid frequent repotting or heavy training that could slow early development. Gentle canopy positioning can help light reach lower growth without placing excessive stress on the plant.

Maintain consistent ventilation and moderate humidity around dense flowers to reduce mould risk. Under suitable conditions, the listed indoor yield is up to 450 g/m², but actual output depends on lighting, environment, plant care and available space.

Outdoor

Outdoor plants are also listed at up to 110 cm, making this variety relatively discreet and manageable. Use a container with ample drainage or a sunny garden position protected from severe wind and prolonged rain. In humid areas, allow generous spacing and inspect dense flower sites regularly. A movable pot can be useful during unsettled autumn weather.

The listed outdoor yield is up to 300 g per plant. This is a reference figure rather than an assured result, as temperature, sunlight, root space and grower experience all influence performance.

Harvest

Flowering is listed at approximately 8–9 weeks. For a traditional New Zealand outdoor calendar, the main harvest period is March–May, though autoflower timing also depends on the sowing date and local climate. Assess flower maturity directly rather than relying only on dates. Blackberry Kush Auto may become a favourite for growers who value compact structure, autumn colour and a sweet berry-Kush finish.
