About Tsunami
Tsunami is a robust sativa-dominant hybrid designed for growers in cooler, wind-exposed locations. It combines lively cerebral effects with a calm focus and carries citrus and pine notes. The strain performs best with shelter from salt spray and good airflow, making it well suited to coastal and northerly gardens. Yields are reliable when plants receive protection and steady feeding, and seeds are feminised for straightforward cultivation.
Tsunami is a sativa-dominant hybrid with a lively growth habit. It carries hybrid stability suitable for variable seasons.
THC levels commonly sit between eighteen and twenty-two percent. That potency offers a clear psychoactive effect best handled by regular users.
CBD is low, generally under one percent. The cultivar is not aimed at CBD-specific therapy.
Tsunami comes from a deliberate cross of Tsunami OG and Coastal Haze. The lineage favours sativa vigour with hybrid resilience to cooler coastal conditions.
Seeds are supplied as feminised to simplify outdoor planting and reduce the need to remove males. This helps secure a consistent crop from a small number of plants.
Growing Tsunami outdoors in a cool Scottish outdoor climate requires careful site selection and wind protection. It is moderately demanding but responds well to basic training and attentive feeding.
Indoor flowering finishes in around eight to ten weeks. Outdoors expect harvest readiness late in the season with potential for a short extension in cool zones.
Yields are medium to high when plants get full sun and shelter from salt-laden winds. Under good conditions expect roughly three hundred and fifty to five hundred grams per square metre outdoors.
Plants develop a tall, airy structure with long internodes and a pronounced central cola. Outdoor specimens often reach between 1.2 and 2.0 metres in sheltered sites.
Indoors Tsunami responds well to SCROG and SOG setups for controlled height in Birmingham grows. Outdoors in Birmingham it benefits from a sheltered, south-facing position to avoid persistent coastal winds.
In Birmingham this strain performs best when given extra protection against damp and salt spray in a cool Scottish outdoor climate. A greenhouse or polytunnel will reduce rot risk and extend the season.
The high gives an initial energetic lift followed by calm focus. Users report creativity without heavy sedation.
Flavours run to sharp citrus over a piney backbone with an earthy finish. The smoke is clean and slightly resinous.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Tsunami favours sheltered, sunny spots with good airflow to limit mould in cooler, damp seasons.
Harvest when most trichomes are milky with some ambers for a balanced effect, typically late season in cooler regions.
Improve airflow, prune lower growth, use a slight tilt for branches to shed water and consider a polytunnel in persistently damp periods.
Use a balanced NPK feed during vegetative growth and switch to higher phosphorus and potassium during flowering, while watching for nutrient lockout in cool soils.
Yes, low-stress training and topping are effective to manage vertical growth and increase lateral bud sites.
It is moderately easy but needs attention to wind and moisture, so new growers should plan shelter and airflow before planting.
Plan for a full season with late harvest potential; a polytunnel can gain two to three weeks on ripening in cool areas.
Yes, Tsunami adapts well to coastal climate cannabis cultivation but needs protection from direct salt spray and fierce winds.
Keep an eye out for aphids, spider mites and thrips, which can stress plants and worsen in cool, damp conditions.
Dry slowly at low temperatures and humidity then cure in jars with gradual burping over several weeks for improved flavour and smoothness.
