Four Oaks Nurseries was founded by the Coutts Brothers, who pioneered the use of supplementary lighting in seedling production, working with Manchester University's Botany Department at Jodrell Bank and Norweb, the local electricity board. The first "Four Oaks Open Day" was organised in 1971 by Norweb to promote the use of growing rooms in commercial horticulture and from that has come an exhibition that has brought the industry together annually ever since.
