Growing Underground is a pioneer operation in so many ways. It is built in an extremely difficult and challenging environment 33 metres underground in the centre of London. It is a full scale successful commercial vertical farm growing a range of micro herbs and baby leaf products. The system has been bespoke built to fit to the tunnels where height and width restrictions are some of the challenges especially putting ebb and flood systems in 4 levels in long thin tunnels. The LED’s are Valoya tubes that allow the bench system to be very close together therefore maximising the space and the production from the amount of floor space available.
