Sour Tsunami CBD Seeds

Genetics & effects

Sour Tsunami CBD is a feminised, CBD-rich selection combining Sour Diesel with an NYC Diesel-derived CBD line. Its 60% sativa and 40% indica composition brings together lively growth, useful branching and a balanced finish. Catalogue figures place CBD at 10–13% and THC at 0.5–1%, though cannabinoid expression can vary with phenotype and growing conditions.

The aromatic profile centres on sour citrus, diesel and light floral notes. Myrcene, beta-caryophyllene and pinene contribute earthy depth, peppery accents and a fresh herbal edge. Individual experiences differ, but some people describe the finished flower as energetic, focused, happy and social at first, followed by a relaxed feel. It may appeal to those who favour a clear, easygoing character rather than a heavily intoxicating experience.

Growing in Australia

This intermediate-level cultivar is suited to hot, dry and temperate Australian environments. Outdoor planting generally aligns with spring, from September to November, once local conditions are stable. Select a sunny position with free-draining soil and reliable airflow. In humid districts, wider spacing and regular canopy checks can help reduce mould risk.

Its Diesel heritage can produce assertive lateral growth, so early shaping may help keep the canopy open and manageable. Feminised seeds are intended to produce female plants, although every garden remains influenced by environment and plant variation. Explore more feminised seeds in the Outback Seed Bank catalogue.

Indoor

Indoors, Sour Tsunami CBD can reach up to 130 cm and may yield up to 450 g/m² under favourable conditions. A flowering period of approximately seven to nine weeks makes it relatively quick for a sativa-leaning cultivar. Gentle training, an even canopy and good air movement can make its branching easier to manage. Monitor stretch as flowering begins and allow enough vertical clearance around lights.

Its diesel aroma may become pronounced late in bloom. Stable temperature, moderate humidity and a clean growing area support flower quality and help reduce risk from excess moisture. Avoid crowding foliage, particularly around dense flower sites.

Outdoor

Outdoor plants may grow up to 170 cm and yield up to 600 g per plant in favourable settings. Warm days, strong sunlight and a sheltered position suit this cultivar well. Temperate growers may prefer the sunniest available location, while hot, dry gardens benefit from consistent irrigation and a moisture-retentive mulch layer that does not touch the stem.

Branches may need support as flowers gain weight. Check plants after rain and during humid spells, removing damaged plant matter and maintaining airflow through the centre of the canopy.

Harvest

Australian outdoor harvest usually falls between March and May, depending on planting time, latitude, phenotype and seasonal weather. Look for swollen flowers, mature resin glands and fading pistils rather than relying only on the calendar. Harvest timing can influence aroma, colour and the subjective character of the finished flower. Handle branches gently and dry them slowly in a dark, ventilated space with stable conditions.
