About Sour Tsunami
Sour Tsunami is a CBD-oriented hybrid developed for medical users and growers who want predictable, low-intoxication results. It combines sour citrus and diesel notes with resinous, compact buds and performs well in modest spaces when trained and protected from damp conditions.
Sour Tsunami is a CBD-dominant hybrid bred for therapeutic use. It favours a balanced, mellow profile over a strong psychoactive punch.
THC levels are deliberately low to reduce intoxicating effects. Expect around 3–6% THC in typical phenotypes.
CBD is the defining trait of Sour Tsunami and commonly reaches 8–12%. That balance gives it broad appeal for medical applications.
Sour Tsunami descends from purpose-bred parents selected for CBD expression. It is commonly listed as Sour Diesel x The Tsu to preserve those traits.
Seeds are commonly sold as feminised to simplify cultivation for small-scale growers. Feminised genetics cut out the need to remove males and help maintain consistent CBD levels.
Growing Sour Tsunami in cool Highland growing conditions requires close attention to airflow and humidity control. It is an intermediate challenge that rewards training and protection from damp.
Flowering normally takes 8 to 10 weeks indoors. Outdoors it usually finishes late in the season with careful site choice.
Yield is moderate with dense, resinous buds under stable conditions. Indoor growers can achieve solid returns by training and optimising light.
Plants remain relatively compact, which suits constrained spaces. Expect a final height commonly between 60 and 120 cm.
It suits both indoor rooms and outdoor plots in Cornwall when given good drainage and sunlight. Indoors it performs well in SCROG or SOG setups and outdoors you should site it where it gets the most afternoon sun in Cornwall.
In Cornwall, growers should expect a longer ripening window when working with cool Highland growing conditions. Cold nights can slow trichome development so consider greenhouse or polytunnel protection to secure consistent cannabinoid profiles.
Effects are subtle and therapeutic rather than intoxicating. Users report a gentle uplift followed by relaxed muscles and clear thinking.
The flavour profile combines sour citrus top notes with a diesel backbone and an earthy finish. Smokers note lemon peel, petrol tang and a woody aftertaste.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Beginners can grow it with attention to humidity and airflow, but intermediate experience improves results.
Use a moderate nutrient schedule with a slight reduction in nitrogen during flowering to encourage resin production.
Increase ventilation, space branches to improve airflow and remove any affected material promptly.
Yes, a polytunnel helps manage rain and cold and can improve ripening in Cornwall when ventilated correctly.
Harvest when many trichomes are cloudy with some amber present for balanced effects; adjust timing to desired CBD/THC ratio.
Low-stress training and SCROG work well to increase light penetration and even bud formation.
Yes, its compact stature and predictable structure make it a strong choice for compact indoor cannabis gardens where space efficiency matters.
Cure in glass jars for at least two weeks, with burping daily for the first week, and longer for smoother flavour.
Maintain standard soil pH of 6.0–7.0 or hydro pH of 5.8–6.5 to keep nutrients available and avoid deficiencies.
Watch for slugs, aphids and spider mites; regular inspection and early intervention work best in UK gardens.
