About Sour Flower
Sour Flower is a versatile hybrid bred from Sour Diesel x Northern Lights that offers an energetic cerebral lift followed by light physical relaxation. It suits growers looking for a mid-to-high THC variety that handles training well and performs predictably in a temperate southern England climate.
Sour Flower is a balanced hybrid with slightly sativa-dominant characteristics. It delivers both cerebral lift and a manageable body calm.
THC typically ranges from 18 to 22 per cent, offering a mid-to-high potency. That potency gives a clear, energetic onset that can mellow with time.
CBD levels are low, usually below one per cent. The plant is therefore not relied on for high-CBD therapeutic effects.
The lineage comes from Sour Diesel crossed with Northern Lights. That mix brings pungent diesel aromatics and a stable, resinous plant structure.
Seeds are supplied feminised to ensure consistent female plants. They establish predictably and react well to training and controlled light cycles.
Under a temperate southern England climate this variety suits growers with some experience. It tolerates variable weather but needs good humidity control and timely pest management.
Indoor flowering usually completes in eight to ten weeks. Outdoor plants in London commonly finish by late September to early October.
Yields are medium to high when fed and trained correctly, with indoor harvests approaching 450 g/m2. Outdoors individual plants can match indoor totals in a good season.
Plants grow to a medium height with a branching, open structure that responds well to training. Expect 90–150 cm indoors and slightly taller outdoors.
Indoors Sour Flower thrives under controlled conditions and responds well to SCROG or low-stress training in London. Outdoors in London it prefers a sunny, sheltered spot and benefits from late-season protection against rain.
Growing Sour Flower in London requires attention to the temperate southern England climate and its late-season rain. Using a ventilated greenhouse or an undercover space helps manage humidity and improves ripening in London.
The high starts with uplifting, focused energy that suits daytime tasks and social situations. As the session progresses it eases into gentle physical relaxation without heavy sedation.
The flavour profile pairs sharp citrus notes with a persistent diesel tang and an earthy base. Lemon rind and petrol notes are noticeable on the exhale.

Begin a mild flush around the final 7 to 10 days before harvest if you prefer a cleaner smoke.
A balanced NPK schedule that reduces nitrogen in late flowering works well; add calcium and magnesium as needed.
Controlled climate cannabis growing stabilises temperature and humidity, reducing mould risk and improving trichome production for Sour Flower.
Inspect plants regularly, use biological controls and keep leaf litter cleared to reduce hiding places for pests.
Top during early vegetative phase and apply low-stress training before flowering to shape the canopy.
Check trichomes for a mix of cloudy and amber and watch pistils for 70 to 90 per cent darkening.
