CBD Purple Kush Auto Seeds

Genetics & effects

Outback Seed Bank presents CBD Purple Kush Auto, a feminised autoflower created from Purple Kush CBD Auto and Purple Afghan CBD Auto genetics. Its profile is approximately 80% indica and 20% sativa, paired with an autoflowering lineage that moves into bloom according to age rather than changing daylight hours. Listed cannabinoid levels reach up to 19% CBD, while THC is listed between 0% and 0.5%.

The aromatic profile blends woody, earthy and sweet notes with berry and citrus accents. Myrcene, limonene and caryophyllene are prominent terpenes associated with this layered character. Experiences are personal and can vary, but some adults describe the overall effect as calming, relaxed and gently happy. The low listed THC level may appeal to those who favour a subtle subjective experience rather than pronounced intoxication.

Growing in Australia

This beginner-friendly autoflower can suit hot, dry districts, temperate regions and cool areas with short seasons. In Australia, spring planting generally falls between September and November, while the traditional autumn harvest period runs from March to May. Because autoflowers follow their own compact timetable, individual plants may finish outside that broader seasonal window depending on sowing date, latitude and local conditions.

Choose an open position with good airflow and strong light. In humid or coastal districts, shelter plants from prolonged rain and allow space around the foliage to reduce mould risk. Gardeners should consider their local climate, property conditions and applicable rules before planting.

Indoor

Indoors, plants may reach up to 100 cm and have a listed yield potential of up to 350 g/m². Their manageable stature suits compact rooms and tents, although actual height depends on container size, light intensity and environmental stability. Use a free-draining medium, avoid frequent repotting and keep the root zone consistently aerated.

• Lighting: Maintain an even schedule suited to autoflowering plants.
• Airflow: Move fresh air through the canopy without blasting young growth.
• Training: Gentle early shaping may help create an even canopy; avoid stressful work late in the cycle.

Outdoor

Outdoors, CBD Purple Kush Auto may grow up to 150 cm and produce up to 90 g per plant. A warm, sunny location can support steady development, while pots allow plants to be moved away from heavy rain, cold snaps or extreme afternoon heat. Purple colour may become more noticeable under cooler conditions, but expression varies between plants.

For spring sowing from September to November, monitor changing temperatures and avoid waterlogged ground. Later sowings can be planned around local conditions when aiming for the March–May autumn harvest period. Cool-short climates benefit from a bright, sheltered site that makes the most of limited warmth.

Harvest

Flowering is listed at approximately seven to eight weeks. Autoflowering plants should be assessed individually rather than by calendar alone. Look for swollen floral growth, mature aromatic expression and natural slowing of fresh flower production. Keep harvested material in a dark, ventilated environment with stable conditions, checking it regularly for excess moisture. Final timing, size, cannabinoid levels and yield can vary with phenotype, climate and cultivation choices.
