Greenhouses, also referred to as glasshouses, are buildings in which plants are grown, ranging in size from small sheds to commercial-size buildings. The general idea of growing plants in an environmentally-controlled area has been around since the time of the Romans. The first modern greenhouses were built during the 13th century in Italy to house exotic plants obtained by explorers in the tropics.
They were known as botanical gardens. The greenhouse concept swept across the Netherlands and into England. In the 1960s, greenhouse structures adapted with the wider availability of polyethylene film. Gutter-connected greenhouses did not become prevalent until the 1980s and 1990s.
These consisted of bays connected by support posts or a common wall. Gutter-connected greenhouses are commonly used today for production and commercial use. Greenhouse gardening has become a popular pastime and career for those looking outside conventional gardening. With a greenhouse, it is possible to grow plants in cold climates and temperatures.
Greenhouses also allow for an ongoing supply of plants throughout the year. Besides these advantages, greenhouses allow owners to have more control over the outcome of their crops. Greenhouses can be controlled through the installation of heating and cooling, ventilation and watering systems.
Proper maintenance of greenhouse plants also aid in insect and pest control. Once considered a luxury, greenhouses are now becoming a common addition to homes.
