The biggest greenhouse in Britain unveiled; This week, workers are putting the finishing touches to Britain's largest hydroponic greenhouse an astonishing construction in white steel and glass. By the time the site is complete in 2010, another six massive greenhouses will have been constructed, providing a home to more than 1.3million tomato, pepper and cucumber plants - grown hydroponically, without soil. Kent is often called the Garden of England. When this village of glass is complete, it will be more like England's factory. The site will contain seven greenhouses, each the size of 10 football pitches. At a time when people are increasingly concerned about industrial-scale farming, this latest, monumental step in the steady, insidious creep of factory farming is a controversial one.
