Sour Tsunami CBD Seeds

Genetics & effects

Sour Tsunami CBD is a feminised, CBD-rich variety combining Sour Diesel with an NYC Diesel-derived CBD-rich selection. Its profile is approximately 60% sativa and 40% indica, pairing lively growth with a balanced overall character. Plants may produce 10–13% CBD and 0.5–1% THC, although cannabinoid levels can vary with phenotype, environment and harvest timing.

The aroma leans towards sharp sour notes, fuel-like diesel and a lighter floral finish. Myrcene, beta-caryophyllene and pinene are prominent in the stated terpene profile. Individual experiences differ, but some people may perceive the effects as energetic, focused or sociable at first, followed by a more relaxed and contented mood. Its layered flavour and contrasting colour make it an interesting choice for growers seeking something beyond a straightforward diesel profile.

Growing in New Zealand

This intermediate-level cultivar can suit temperate areas and hot, dry microclimates across New Zealand. For outdoor growing, spring planting generally falls between September and November, once cold nights and late frosts have eased. Choose a sunny position with airflow and shelter from severe wind. In wetter districts, spacing, selective pruning and protection from prolonged rain can help reduce mould risk as flowers gain density.

Use an airy, free-draining medium and avoid keeping the root zone continuously saturated. The plant’s sativa influence can produce noticeable vertical growth, so early planning is useful where space is limited. Actual height, flowering time and output will depend on local conditions, grower experience and phenotype.

Indoor

Indoors, Sour Tsunami CBD may reach up to 130 cm and usually flowers for around 7–9 weeks. Gentle low-stress training, topping or a screen can help create an even canopy and make better use of available light. Allow room for stretch when changing the light cycle, and maintain steady air movement around developing flowers.

Under suitable conditions, indoor output may reach up to 450 g/m². This is an indicative upper figure rather than an assured result. Monitor humidity closely in late flowering, keep the growing area clean and support heavier branches where needed.

Outdoor

Outdoor plants may grow up to 170 cm and can produce up to 600 g per plant in favourable conditions. A north-facing site with long sun exposure is preferable. Hot, dry conditions may suit this variety, provided moisture remains consistent and roots do not dry out excessively. In cooler or more humid locations, a sheltered position and regular canopy checks are especially useful.

Its combination of sour, diesel and floral aromas can become pronounced late in the season. Consider site privacy and airflow when choosing a position. Inspect flowers after heavy rain and remove damaged plant material promptly to reduce risk around dense areas.

Harvest

In New Zealand, the typical outdoor harvest window is March–May, with exact timing shaped by planting date, latitude and seasonal weather. Check flower maturity rather than relying only on the calendar. Indoors, harvest commonly follows the stated 7–9-week flowering period.

Handle mature flowers carefully to preserve their aroma and structure. Gradual drying in a dark, well-ventilated space can help maintain the sour-diesel profile and floral detail. For growers who favour expressive aromas, moderate height and a CBD-rich cannabinoid balance, Sour Tsunami CBD may become a favourite catalogue selection.
