About Birthday Cake

Birthday Cake is an indica-dominant hybrid prized for its dessert-like aroma and dense, trichome-rich buds. It typically carries THC in the 20–25% range and low CBD, producing a potent, sedative-leaning effect that works well for evening use. The plant stays medium in height and responds well to training, making it suitable for growers who manage canopy and airflow carefully. In humid greenhouse environments and UK outdoor spots, attention to ventilation and mould prevention is essential to protect bud quality. With consistent feeding and good environmental control, Birthday Cake delivers medium to high yields and a memorable sweet profile.

Grow Difficulty:

Growing Birthday Cake is moderately demanding under humid greenhouse environments due to an increased risk of bud rot. Regular pruning, good airflow and proactive mould checks are essential.

Flowering Time:

Flowering typically finishes in eight to nine weeks indoors. Outdoors, plants usually finish by early October in a UK season when conditions are favourable.

Yield:

Yields are medium to high when training and feeding are consistent. Under controlled indoor environments you can expect yields around 400 to 500 g/m² with optimisation.

Height:

Plants remain a manageable medium height with sturdy branches that support dense buds. They respond well to topping and screen-of-green techniques to keep the canopy even.

Environment:

Indoors, Birthday Cake performs well in tents or small rooms with controlled light cycles in Nottinghamshire. Outdoors it finishes reliably in sunny microclimates but needs shelter from prolonged damp in Nottinghamshire.

Climate:

Growing Birthday Cake in Nottinghamshire with humid greenhouse environments requires strict humidity control and continuous ventilation. Maintain 40–50% RH during flowering and inspect for mould frequently in Nottinghamshire.

Any tips for smell control indoors?

Verified answer
Fit a quality carbon filter to your extraction and keep intake filtered; also remove fan leaves that overly contribute to odour late in flowering.
