About Blueberry Jam

Blueberry Jam is an indica-dominant hybrid that brings pronounced blueberry and jammy notes alongside relaxing body effects. It flowers in eight to nine weeks and offers medium to high yields when grown with attention to airflow and nutrient balance. In London its compact stature and resilience make it a strong choice for gardeners working in mild southern growing climate conditions. Growers should focus on humidity control, good ventilation and light training to maximise bud quality and terpene retention.

Grow Difficulty:

Grow difficulty is intermediate and manageable for those with basic experience. It performs well in a mild southern growing climate and benefits from steady humidity control.

Flowering Time:

Flowering typically completes in eight to nine weeks. Outdoor growers in London can expect harvest in early autumn.

Yield:

Yields are medium to high under attentive care. Expect denser buds when given good nutrients and adequate light.

Height:

Plants stay compact to medium, with bushy internodal spacing. Expect heights around 80 cm to 150 cm depending on training.

Environment:

Indoors, Blueberry Jam responds well to SCROG and topping to control its bushy growth. Outdoors in London it finishes reliably and benefits from sheltered, sunny spots.

Climate:

In London, the mild southern growing climate allows Blueberry Jam to finish outdoors with lower risk of rot. Provide good airflow and moderate humidity control to make the most of the season.

Common question Posted by Urbanseedbank Answered
Q
I have a 1.2 x 1.2 m tent, how many plants?
A
Verified answer
Two to four plants under SCROG will maximise space while allowing good airflow and light spread.
Common question Posted by Urbanseedbank Answered
Q
Should I top it or leave a single cola?
A
Verified answer
Top once or twice to create multiple main colas and improve light distribution; single-cola grows waste light on compact strains.

Do I need to flush before harvest?
