About us
What we do
Northern Leaf runs a large-scale greenhouse facility in Jersey, the largest of the Channel Islands, that cultivates and processes high-THC cannabis flower for medicinal use.
The 100,000 sq.ft site has been developed through more than £30m of investment over the past four years and supplies regulated medical markets in the UK and Europe.
How we operate
Accredited to the highest standards, Northern Leaf holds a commercial licence from the UK Home Office that allows the cultivation, possession and supply of medical cannabis flower.
Strict pharmaceutical quality systems are in place across every step of the manufacturing process to ensure compliance with GACP and EU-GMP standards, which regulate how medicinal cannabis is cultivated, processed, tested and prepared for use in medicines.

How we grow
Northern Leaf’s cultivation and processing facility is based in St Lawrence, Jersey, operating from a repurposed greenhouse originally built for horticulture and rebuilt for controlled-environment medical cannabis production.
The greenhouse uses advanced systems for CO₂ injection, automated irrigation, environmental monitoring and air purification to help reduce pathogen risk and support consistent growing conditions. The growing area is divided into 20-by-80-meter compartments so different genetics and crop stages can run at the same time.
Plants are grown using coco coir, selected for its performance and lower environmental impact, with drying carried out in purpose-built facilities designed to control moisture loss and maintain product consistency.
