About Sourdough
Sourdough is a sativa-dominant hybrid selected for flavour and clarity. It combines a distinctive bready, sour aroma with citrus top notes and delivers an uplifting, cerebral high alongside gentle body relaxation, suited to daytime use.
Sourdough is a sativa-dominant hybrid with lively growth. It leans towards an energetic and creative effect profile.
THC levels typically range from 18% to 22%. This delivers a clear psychoactive hit without overwhelming experienced users.
CBD is low, generally under 1%. Expect a primarily recreational cannabinoid balance rather than a high-CBD therapeutic profile.
The precise parentage of Sourdough is not well documented. It appears to derive from hybrid lines selected for flavour and vigour.
Seeds are available as feminized lines to deliver reliable female crops. Autoflower variants are rarely encountered for this variety.
Growing Sourdough in cool northern summers requires careful attention to light and airflow. It is best treated as an intermediate variety for growers able to manage humidity and temperature.
Flowering typically takes eight to ten weeks under good conditions. Some phenotypes may stretch a little longer if they receive low light.
Yield is medium to high with proper canopy training and feeding. Indoors you can reasonably aim for around 400-500 g/m² under strong lighting.
Plants tend to stay compact with a sturdy central cola, making them suitable for SCROG. Typical height ranges from 80 cm to 160 cm when trained.
Indoors Sourdough responds well to controlled environments and fits neatly into most grow rooms in Dorset. Outdoors in Dorset it benefits from shelter and a warm, sunny late summer if conditions allow.
In Dorset, cool northern summers require shelter and good drainage to avoid mould. Sourdough ripens best when given a warm, sheltered microclimate and a dry late summer.
The high is uplifting and clear, suitable for daytime activities. It also brings a gentle body relaxation that helps unwind without heavy sedation.
A distinct bready sour note sits at the centre of the aroma balanced by bright citrus. Earthy, herbal undertones round out the flavour profile.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Full-spectrum LED lights at moderate intensity work well; aim for 18 hours in veg and 12 hours in flower.
Keep humidity below 50% in late flowering to reduce mould risk, especially important in cooler, damper climates.
Use a balanced feed with a slightly lower nitrogen level in flowering and boost phosphorus and potassium for bud development.
Look for mostly cloudy trichomes with some ambers and a robust aroma; harvest timing depends on your preferred effect.
Yes, but it needs a sheltered, sunny spot and attention to drainage to cope with British conditions.
Selective pruning and topping help maintain a strong central cola and improve light penetration to lower buds.
Increase airflow, keep canopy density moderate and monitor humidity closely to prevent botrytis and mould.
SCROG and low-stress training work well to control height and boost yields in limited spaces.
Prioritise ventilation, odour control and even light distribution; consistent environmental control is more important than extreme light intensity.
Many growers perform a short flush with plain water to improve smoke quality, but follow your nutrient schedule and plant health.
