Super Silver Haze Seeds

Genetics & effects

Super Silver Haze is a feminised, photoperiod selection with a reported lineage of Northern Lights #5 × Skunk #1 × Haze. Its profile is approximately 70% sativa and 30% indica, combining vigorous haze-style growth with a somewhat more manageable structure. Outback Seed Bank presents this variety for growers seeking established genetics, generous production potential and a distinct aromatic finish.

THC is listed at approximately 18–21%, while CBD is listed at around 0.05–0.15%. Individual experiences can vary, but consumers may describe the effects as energetic, euphoric, uplifting and happy at first, followed by a more relaxed sensation. Citrus and sweet notes often sit over earthy, spicy and haze-like flavours. Myrcene, caryophyllene and limonene are among the associated terpenes, though aroma and colour can shift with phenotype and growing conditions.

Growing in Australia

This variety is best suited to growers with intermediate experience. It can develop substantial height and branching, so early planning is valuable. Hot, dry and temperate Australian conditions may suit outdoor cultivation where local weather remains stable. In humid districts, generous spacing and steady airflow can reduce the risk of mould around dense flowers.

Outdoor planting generally aligns with southern-hemisphere spring, from September to November. Exact timing depends on latitude, overnight temperatures and daylight hours. Because cultivation rules differ across Australia, growers should review the requirements applying in their state or territory before planting.

Indoor

Indoors, Super Silver Haze may reach up to 160 cm and typically flowers for about 9–10 weeks. Its stretch can be guided with topping, low-stress training or a screen, helping create an even canopy and use available light efficiently. Allow enough vertical clearance before changing the light cycle.

• Flowering: approximately 9–10 weeks
• Indoor height: up to 160 cm
• Indoor yield: up to 600 g/m² under favourable conditions
• Key focus: canopy control, airflow and consistent environmental settings

Keep branches well supported as flowers gain weight. Monitoring humidity, irrigation and air movement throughout bloom can help maintain flower quality. Listed figures are guidance rather than assured outcomes.

Outdoor

Outdoors, plants may reach up to 220 cm where root space, sun and season length are sufficient. Choose a bright, sheltered position with free-draining soil and room for side branching. Staking or trellising can support the frame during windy weather and later flowering.

• Outdoor height: up to 220 cm
• Outdoor yield: up to 700 g per plant in favourable settings
• Preferred climate: hot, dry or temperate

Regular inspection is especially useful after rain or during humid spells. Open branching, sensible watering and removal of damaged plant material can reduce mould risk without compromising the natural shape.

Harvest

Australian outdoor harvest usually falls between March and May, depending on planting date, latitude, phenotype and seasonal conditions. Look for mature flower structure, developed aroma and changes in resin-gland appearance rather than relying on the calendar alone. The finished flowers may show a favourite mix of citrus brightness, earthy sweetness, warm spice and lingering haze character.
