Haze #1 Seeds

Haze #1 is a classic, sativa-dominant option presented in the Outback Seed Bank catalogue for experienced growers seeking vigorous growth, an extended flowering phase and a distinctly aromatic finish. These feminised seeds are intended to simplify crop planning by focusing on female plants. With approximately 90% sativa and 10% indica heritage, this cultivar demands patience, space and attentive environmental management.

Genetics & effects

The lineage combines Mexican Haze, Thai, Colombian and Jamaican landrace-derived genetics. Plants may develop narrow leaves, generous spacing between nodes and strong vertical growth. Reported THC potential sits around 18–22%, while CBD is listed at approximately 0.1–0.4%; actual composition can vary with phenotype, environment and post-harvest handling.

Earthy and floral notes form the aromatic base, accompanied by lemon and recognisable haze character. Myrcene, limonene and beta-caryophyllene are among the associated terpenes. Individual experiences differ, but some consumers describe the effects as creative, euphoric, happy or uplifting. Potency and personal response can vary.

Growing in Australia

Haze #1 is rated for expert growers because its long flowering period and vigorous stretch require close canopy, airflow and climate control. It is most compatible with hot, dry or temperate conditions. High humidity late in the season may increase mould pressure around dense flowers, so site selection and regular inspection are important.

For outdoor cultivation in the southern hemisphere, spring planting generally falls between September and November. Local temperatures, daylight hours and microclimates should guide exact timing. Growers should confirm applicable rules before acquiring or cultivating seeds.

Indoor

Indoors, plants may reach up to 150 cm and can stretch considerably after flowering begins. Allowing enough headroom and shaping the canopy early may help maintain even light exposure. Strong air movement, stable humidity and support for longer branches can reduce risk during the 12–14 week flowering phase.

• Flowering: approximately 12–14 weeks
• Indoor height: up to 150 cm
• Indoor yield: up to 650 g/m² under favourable conditions

Outdoor

Outdoors, Haze #1 may grow to around 200 cm where root space, sun and warmth are plentiful. A sheltered, well-ventilated position can help branches cope with wind while allowing moisture to disperse. Its extended schedule makes reliable autumn weather especially valuable. In cooler districts, growers may prefer a protected setting to manage falling temperatures and seasonal rain.

• Outdoor height: up to 200 cm
• Outdoor yield: up to 800 g per plant under favourable conditions
• Climate preference: hot, dry or temperate

Harvest

Australian outdoor harvest commonly occurs from March to May, although this long-flowering cultivar may finish toward the later part of that window. Phenotype, planting date, latitude and seasonal weather can shift maturity. Rather than relying on the calendar alone, assess flower development and overall plant condition. Yield figures are potential maximums, not assured outcomes.
