00:00London growers say heat waves have damaged crops and cut pepper production by up to 40% this summer.
00:08Lee Valley Growers Association says it lost 27,000 kilograms of peppers during 10 weeks of picking.
00:15The group supplies much of Britain's cucumbers and sweet peppers from glass houses in London, Essex and Hertfordshire.
00:22It says the extreme heat affected pepper roots, while hot weather also reduced bee activity hitting tomato crops.
00:30The association says rising energy, fertiliser and labour costs are adding to pressure on growers.
00:36It says growers have collectively lost around £15 million this year.
00:41Retailers say higher costs could affect prices.
