Pineapple Express Auto Seeds

Genetics & effects

Pineapple Express Auto is a feminised autoflower from Pineapple Express and ruderalis autoflowering lineage. Its profile is approximately 60% sativa and 40% indica, combining compact growth with a lively character. Outback Seed Bank presents it as an approachable option for growers exploring autoflower seeds.

THC is listed at an indicative 12–15%, while CBD is listed at 0.1–0.5%. Individual experiences vary, but the effects may feel uplifting at first, followed by a relaxed and calming finish. Some people may find this balance suitable for laid-back social settings or quiet personal time. Sweet, tropical and fruity notes lead the flavour, with sour pineapple accents adding brightness. Myrcene, limonene and beta-caryophyllene contribute to the aromatic profile.

Growing in Australia

This beginner-friendly cultivar is suited to hot, dry and temperate Australian conditions. Autoflowering genetics move according to plant age rather than a change in daylight hours, making seasonal planning straightforward. Even so, local temperature, humidity, nutrition, container size and daily light exposure can alter growth time, colour, aroma and final output.

For outdoor cultivation, spring planting generally falls between September and November. Choose a bright, well-ventilated position and avoid persistently damp ground. In warmer districts, afternoon protection during severe heat may reduce stress. In temperate areas, starting after the main frost risk has passed can support steadier early growth.

Indoor

Indoors, Pineapple Express Auto generally reaches 60–110 cm. Its compact form can suit tents and rooms where vertical space is limited. A stable light schedule, gentle airflow and a free-draining medium help maintain even development. Avoid heavy feeding or frequent disruption, as autoflowers have limited time to recover from setbacks.

• Flowering phase: approximately 7–8 weeks
• Indoor height: approximately 60–110 cm
• Indicative yield: up to 600 g/m² under favourable conditions

Keep foliage spaced where practical and monitor humidity around dense flower sites to reduce mould risk. Low-stress canopy guidance may help improve light distribution, although simple methods are often a favourite choice for first-time autoflower growers.

Outdoor

Outdoor plants are also expected to reach about 60–110 cm, making them relatively discreet and manageable. Use a sunny site with good air movement and soil or potting mix that drains freely after rain. Containers can make it easier to reposition plants during storms, cold snaps or prolonged heat.

• Preferred climates: hot, dry or temperate
• Outdoor height: approximately 60–110 cm
• Indicative yield: up to 150 g per plant under favourable conditions

Harvest

Australia’s broad seasonal harvest window is March–May, although autoflowers started in spring may finish earlier because their cycle is age-dependent. Assess maturity from overall flower development rather than relying only on a calendar. Actual timing and yield vary with environment and grower technique, so all figures should be viewed as guides rather than assured outcomes.
