About Medellin

Medellin is a classic sativa landrace from Colombian stock that favours clear, energising effects and vigorous vertical development. It performs well for growers in Bristol when attention is paid to airflow, mould prevention, and training to control height in the region’s mild southern conditions.

Grow Difficulty:

Medellin suits growers with intermediate experience because it needs attention to humidity and airflow in a mild southern growing climate. Regular pruning and vigilant mould checks are required to maintain bud quality.

Flowering Time:

Flowering typically takes 10 to 12 weeks under stable conditions. Outdoor plants usually finish late in the season in temperate regions.

Yield:

Yield is medium to high for those who control stretch and light exposure effectively. Outdoor specimens in favourable conditions can produce substantial single-plant harvests.

Height:

Plants show a tall, lanky structure with long internodes and vigorous vertical growth. Indoor growers should use training to limit final height and improve bud sites.

Environment:

Indoors, Medellin responds well to screen-of-green and topping to manage vertical growth in Bristol. Outdoors in Bristol it can stretch tall and reward growers with sizeable colas when given space and good airflow.

Climate:

In Bristol, Medellin thrives when growers account for the mild southern growing climate and protect buds from persistent damp. Good ventilation and targeted defoliation reduce mould risk while keeping vigour.
