Banana Kush Seeds

Genetics & effects

Banana Kush is a feminised Ghost OG × Skunk Haze cross, commonly described as 60% indica and 40% sativa. Its profile is reported at 18–22% THC and 0.1–0.3% CBD, though cannabinoid levels can vary with phenotype, environment and cultivation choices.

The aroma and flavour lean towards ripe banana, sweet tropical fruit and citrus, layered with earthy, pungent and skunky notes. Limonene, beta-caryophyllene and myrcene are associated with this broad aromatic profile. Individual experiences differ, but consumers often describe the effects as relaxed, happy and euphoric, with an uplifted, creative or talkative edge. Browse more feminised seeds for related options.

Growing in New Zealand

Banana Kush is considered an intermediate-level cultivar that suits temperate or hot, dry conditions. In New Zealand, outdoor planting generally aligns with spring, from September to November, once local temperatures are settled and harsh weather is less likely. Site choice matters: prioritise strong sunlight, airflow and shelter from persistent rain or damaging winds.

Regional conditions vary considerably between the upper North Island, cooler southern districts and exposed coastal areas. Monitor humidity closely, especially as flowers become denser. Good spacing, selective pruning and protection from prolonged autumn rain can reduce the risk of mould. Always check the rules that apply in your location before acquiring or growing cannabis seeds.

Indoor

Indoors, plants may reach up to 160 cm, so allow enough vertical room for both the canopy and lighting. Training and canopy management can help make productive use of the available space. Keep air moving through and beneath the foliage, and maintain stable temperature and humidity rather than making abrupt environmental changes.

The listed flowering period is approximately seven to nine weeks. Under suitable conditions, indoor yield is stated as up to 550 g/m². This figure is a reference rather than an assured outcome, as lighting, nutrition, plant health, experience and phenotype all influence final performance.

Outdoor

Outdoor plants can reach up to 200 cm and may produce up to 710 g per plant in favourable conditions. Choose a sunny position with free-draining soil and enough room for branching. In wetter parts of New Zealand, overhead cover and reliable airflow may be useful late in the season, provided plants still receive suitable light and ventilation.

Regular observation is particularly important after heavy rain or during humid spells. Support larger branches as flowers gain weight, and remove damaged plant material promptly. Growers in cooler areas may favour an early spring start in a protected setting before moving plants outside when conditions improve.

Harvest

In the southern hemisphere, the typical outdoor harvest window falls between March and May. Exact timing depends on planting date, local climate and phenotype. Assess flower maturity directly rather than relying only on the calendar. Before cutting, inspect flowers carefully for moisture damage or mould, particularly after autumn rain. Harvest in dry conditions where possible, then move branches to a clean, dark and well-ventilated drying area.
