About Sour Grape

Sour Grape blends the punch of diesel terpenes with a pronounced sour grape sweetness to produce a creative, uplifted experience followed by a calming body effect. It flowers in around 8-10 weeks and suits growers who can manage airflow and mould prevention, particularly in cooler, damper climates like Nottingham.

Grow Difficulty:

Growing Sour Grape is moderately challenging in outdoor UK conditions and requires attention to mould in a rainy autumn harvest season. Good airflow, timely pruning and clear disease prevention strategies reduce risk.

Flowering Time:

Flowering generally completes in 8-10 weeks under stable indoor lights. Outdoor plants in Nottingham often finish by mid to late autumn if weather allows.

Yield:

Yield is medium to high when plants receive steady nutrients and consistent training. Outdoors you can achieve respectable harvests with early-season veg and shelter from wind.

Height:

Plants develop a medium stature with a central cola and healthy side branching. Stretch is manageable with topping or low-stress training to create an even canopy.

Environment:

Indoors in Nottingham Sour Grape responds well to SCROG and SOG setups for even light distribution. Outdoors in Nottingham it prefers a sheltered, sunny spot away from damp exposure late in the season.

Climate:

In Nottingham Sour Grape tolerates cool summers but requires careful attention during a rainy autumn harvest season. Extra drying space and regular mould checks are essential when pulling buds into a damp environment.
