Where does GW grow cannabis?

GW's cannabis plants are grown under computer-controlled conditions in secure glasshouses at a secret location in the UK. GW has developed a highly sophisticated cultivation process to ensure plant material grown is of sufficient quality and consistency to be suitable for incorporation into pharmaceutical products.

Strict Standard Operating Procedures (SOPs) are followed to ensure non-contamination by chemicals, infestation or fungal growth, consistency of content, methods of harvest, drying, primary extraction, storage and onward consignment. Temperature, humidity, total light and photoperiod are all controlled by computer.

The facility is situated in the South of England but for clear security reasons we do not divulge the precise location.
