About Xj13
Xj13 is a sativa-dominant hybrid bred from Jack Herer x G13 Haze, valued for bright, cerebral effects and a citrus-forward terpene profile. It performs well indoors with training and outdoors in sheltered locations, but growers in Surrey should plan for a short outdoor growing season and protect plants from late autumn damp to avoid mould.
Grow Difficulty:
Xj13 is moderately challenging to cultivate outdoors in a short outdoor growing season because it prefers a longer ripening window. In Surrey growers should start early and be prepared to use protection or moveable covers if autumn weather arrives early.
Flowering Time:
Flowering typically takes about 8–9 weeks under controlled indoor conditions. Outdoors, select early-finishing phenotypes to avoid late-season rain.
Yield:
Yields are moderate to high when plants receive steady nutrients and good canopy management. In a short outdoor growing season yields often drop unless the grower adjusts timing and microclimate.
Height:
Plants exhibit a sativa-like stretch with long colas and a lanky structure. Without training they can exceed two metres outdoors.
Environment:
Indoors Xj13 responds well to SCROG and low-stress training, allowing Surrey growers to control stretch and finish within nine weeks of flowering. Outdoors, growers in Surrey should favour glasshouses or temporary covers to protect buds from autumn dampness.
Climate:
Growing Xj13 in Surrey with a short outdoor growing season requires careful planning to finish before persistent autumn rain. Choose early-flowering phenotypes and provide shelter to minimise the risk of mould and rot.
