About Irish Cannonball

Irish Cannonball is a compact sativa-dominant hybrid originating from hardy landrace stock and a resinous indoor parent. It offers a bright, focused high with citrus-forward flavours and a manageable stature that suits growers with limited space or cooler outdoor sites.

Grow Difficulty:

Growing Irish Cannonball requires intermediate experience and attention to ventilation and humidity in cool Highland growing conditions. Novice growers can succeed with steady environmental control and patient observation.

Flowering Time:

Indoor flowering usually finishes in 8 to 9 weeks under stable conditions. Outdoors it typically matures late in the season where conditions allow.

Yield:

Yield is moderate to good for a compact cultivar, often producing in the mid hundreds per square metre indoors. Outdoor harvests depend on season length and site quality but can be comparable in favourable spots.

Height:

Plants remain relatively short and bushy, commonly reaching 60–100 cm when well managed. The compact frame responds well to low-stress training and canopy management.

Environment:

Irish Cannonball does well in controlled indoor environments and suits small tents or grow spaces in towns. In Derry it can also be grown outdoors in sheltered microclimates, provided protection from persistent damp.

Climate:

In Derry's cool Highland growing conditions Irish Cannonball benefits from sheltered, sun-warmed sites and good airflow. Consider south-facing exposure and covers early in the season to help maintain steady temperatures.
