Types of Greenhouses
A greenhouse, otherwise called as glass house, is a building where plants are grown. Greenhouses are commonly used by botanists, plants businessmen, and passionate gardeners in cool places since they are designed in such a way that they allow sunlight to enter their interior space and prevent the heat within them from escaping. Greenhouses have transparent covering which enables the sunlight to pass through them easily.

The sunlight from the outside is then absorbed by the materials inside the greenhouse, hindering the heat from escaping easily. Moreover, the transparent covering of the structure also reflect the leaving heat back to the interior of the structure.

If you are planning to build a greenhouse of your own, take a look on the different types of greenhouses below to know what you want for yourself.

• Even-span Greenhouses. An even-span is a full-size greenhouse. It has one gable end that is attached to a single side of a building. It is the largest greenhouse one can build. It is also the most costly among all kinds of greenhouses. Even-span greenhouses also have good air circulation.
• Free-standing Greenhouses. As its name suggests, a free-standing greenhouse is constructed as a separate structure. They are intentionally constructed away from other structures in order to gather more sunlight. However, since they are constructed far from existing buildings, new electricity and water lines should be installed especially for them. Free-standing greenhouses vary widely in sizes depending on the builder's available space and budget.
• Lean-to Greenhouses. These greenhouses are half-greenhouses. The ridge of a lean-to greenhouse is attached to a side of a building. This type of greenhouse is very much recommended for builders who have limited space. It is also the cheapest kind of greenhouses.
• Window-mounted. This type of greenhouse is attached to either sides of your house. This is very much suitable for people who are only growing a few numbers of plants. This kind of greenhouse costs low.
