According to secretary Lee Stiles: "The cucumbers produced in the area are of a higher quality than those from other regions of the UK or abroad - thinner-skinned and less bitter. If they were called Lea Valley cucumbers, consumers would be more educated about where they come from."
But Cucumber Growers Association technical officer Derek Hargreaves questioned the claim. "The cucumbers grown commercially in this country are grown in the same way, in rock wool."
The Lea Valley area of Hertfordshire grows around 80 million cucumbers a year.
