Greenhouse cultivation. Cultivation of lettuce, Lactuca sativa, in a large, commercial greenhouse or glasshouse. This type of greenhouse is known as the ridge and furrow design due to the shape of its roof. Growing plants in greenhouses allows for careful control of conditions. Within the greenhouse plants are protected from weather and pests. Light intensity, temperature and moisture levels can also be maintained at optimum levels. Use of greenhouses can also prevent pesticides and fertilisers from polluting the environment.
