About Blueberry Yum Yum

Blueberry Yum Yum is an indica-dominant hybrid that produces dense, resinous buds with a strong blueberry and sweet profile. It is suited to greenhouse or controlled indoor grows and performs well in sheltered outdoor sites when humidity is managed.

Grow Difficulty:

This cultivar is intermediate to grow and responds well to topping and low-stress training in a moist western coastal climate. Growers must monitor humidity and ventilation closely to avoid mould issues.

Flowering Time:

Flowering finishes in eight to nine weeks under attentive care. Outdoor crops in Surrey typically reach harvest in late September to early October.

Yield:

Yields are moderate with dense, resinous buds when humidity is controlled. In my Surrey greenhouse I achieve consistent results by prioritising airflow and drying space.

Height:

Plants remain medium in stature with a strong central cola and productive side branches. Expect final heights around 0.8 to 1.5 metres depending on training and pot size.

Environment:

Blueberry Yum Yum suits greenhouse and indoor setups and benefits from controlled feeding and light schedules. In Surrey a sheltered greenhouse balances protection from frequent rain with access to natural light.

Climate:

Growing Blueberry Yum Yum in Surrey requires diligence because the moist western coastal climate increases mould risk. A well-ventilated greenhouse with dehumidification provides the best chance of a clean crop in Surrey.

My plants are stretching in early flower, how can I control that?

Verified answer
Reduce night temperature slightly, adjust light height and consider light pruning to redistribute vigour before stretch completes.
Common question Posted by Urbanseedbank Answered
Q
How should I dry Blueberry Yum Yum in Surrey?
A
Verified answer
Dry in a cool, dark room around 16-18°C and 45-55% RH and use a dehumidifier if needed to counter the moist western coastal climate.
Common question Posted by Urbanseedbank Answered
Q
How often should I water in 11 litre pots?
A
Verified answer
Water when the top 2 cm of medium is dry, typically every 2-4 days depending on stage and environment; water until you see run-off and then allow a light dry down.
Common question Posted by Urbanseedbank Answered
Q
Is supplemental CO2 worth it in a greenhouse?
A
Verified answer
CO2 can boost yields if light, nutrients and ventilation are optimised, but for most UK greenhouse setups it is not essential and adds complexity.
