GreenhousesGreenhouses are structures that are built in order to grow plants in an environment that is controlled. The environment in
Greenhouses does not really have typical atmospheric conditions. This is because it is ceiled with glass all around so that only sunlight enters. The proportions of gases [oxygen, carbon dioxide, etc.] are all controlled in order to benefit the growth of plant life. A greenhouse is normally used by two kinds of people. The first set of people use it for scientific or environmental operations, such as propagating new species or for looking after endangered ones. The second type of people that use them include enthusiasts who can afford to have their own choice of plants.
