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.

Grow Difficulty:

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.

Flowering Time:

Indoor flowering usually completes in eight to ten weeks. Outdoor plants in London commonly finish by late September to early October.

Yield:

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.

Height:

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.

Environment:

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.

Climate:

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.
