About Black Ube

Black Ube is an indica-dominant hybrid bred from Blackberry x Ube that combines deep purple hues, rich dark-fruit terpenes and robust resin production. It offers a clear initial buzz that develops into strong physical relaxation and is well suited to growers who can manage humidity and airflow in greenhouse or outdoor settings. In Somerset growers prefer greenhouse protection to control moisture, but outdoor crops can do well where canopy management and timely pruning reduce mould risk. Expect a flowering time of eight to ten weeks and medium to high yields when plants remain healthy throughout bloom.

Grow Difficulty:

Under humid greenhouse conditions this cultivar requires attentive ventilation and proactive mould prevention. It suits growers with some experience of humidity control rather than complete beginners.

Flowering Time:

Flowering completes in about eight to ten weeks indoors. Outdoor harvest in Somerset usually falls in late September to early October.

Yield:

Yields are medium to high when plants are kept free of disease and bud rot. Expect roughly 400–600 g/m² indoors and 200–350 g per plant outdoors under good care.

Height:

Black Ube stays relatively compact with strong lateral branching. Plants commonly reach between 0.8 and 1.6 metres with proper training.

Environment:

Black Ube performs well both indoors and outdoors in Somerset when the season is warm. In Somerset greenhouse growing gives more control while outdoor crops demand rigorous mould management.

Climate:

Growing Black Ube in Somerset with humid greenhouse conditions demands strict humidity control and strong airflow. Consistent dehumidification and regular pruning lower rot risk and support healthy bud development.
