Bubba Kush Auto Seeds

Genetics & effects

Presented in the Kiwi Seed Bank catalogue, Bubba Kush Auto combines White Widow Autoflower with Pre-98 Bubba Kush and autoflowering ruderalis heritage. The result is a feminised, THC-forward autoflower with an estimated 80% indica and 20% sativa profile. Listed THC content is 15–22%, while CBD is listed at 0–0.3%.

Its terpene profile features beta-caryophyllene, myrcene and limonene, supporting a full-flavoured mix of chocolate, roasted coffee, sweet earth, pungent spice and classic Kush. Experiences are subjective, but consumers commonly describe the character as powerful, calming and deeply relaxed, with happy feelings that may become sleepy as the session settles.

Growing in New Zealand

This beginner-friendly cultivar suits hot, dry and temperate conditions. Its automatic flowering habit means bloom begins according to plant maturity rather than changing daylight hours. For outdoor growing in New Zealand, spring planting falls between September and November. Select a sunny, sheltered position with free-draining soil and reliable airflow.

New Zealand weather can shift quickly, particularly near the coast and during late summer. Avoid persistently damp foliage, allow space between plants and monitor dense flowers after rain to reduce the risk of mould. The plant’s compact structure can suit discreet spaces, although final size and production depend on light, root volume, nutrition, weather and general growing conditions.

Indoor

Indoors, Bubba Kush Auto can reach up to 100 cm, making it a practical candidate for smaller tents and height-limited rooms. Gentle canopy management can help expose lower growth, but heavy or repeated training may slow a short autoflowering cycle. A light, aerated medium and steady environment are preferable to frequent changes.

The flowering phase is listed at approximately 8–9 weeks. Indoor production is listed at up to 400 g/m² under favourable conditions. Good extraction is useful as the pungent coffee, earth and Kush aromas strengthen late in bloom. Browse our feminised seed selection for further choices.

Outdoor

Outdoors, plants may reach up to 150 cm and produce up to 150 g per plant. Warm northern sites may offer a longer spell of settled weather, while cooler or wetter regions benefit from wind protection and strong drainage. Containers can provide flexibility when frost, storms or extended rain are expected.

Check flowers regularly as autumn humidity increases. Support branches if they become top-heavy, keep the surrounding area clear and avoid leaving plants crowded against walls or dense vegetation.

Harvest

New Zealand’s main outdoor harvest season runs from March to May. Because this is an autoflower, individual plants may finish outside that broader seasonal window depending on sowing date and conditions. Look for swollen flowers, mature resin coverage and fading pistils rather than relying on the calendar alone. At maturity, expect dense buds with dark green colour, warm earthy sweetness and pronounced chocolate-coffee Kush notes.
