Greenhouses can be beautiful and functional structures for your garden especially when you are into gardening. If you have ever wondered if it would be worth investing in a greenhouse, we have some points to help you sort it out.

Before we jump onto other sections, let’s understand the concept behind a greenhouse…

What is a greenhouse?

Greenhouse, also called a glasshouse, is a structure designed for the protection of plants against extreme temperatures. It is made of a transparent material like glass but earlier it was used to be a brick or timber shelter with a certain proportion of windows space. These beautiful buildings allow growing seasons to be extended and protect plants from excess cold or heat as well as pests.

In simple words, a greenhouse serves as a shield between nature and the plants that are tender or out-of-season. The structure maintains an ideal temperature for the plants to grow as both heating and cooling can be regulated. The interior is exposed to sunlight making it significantly warmer than the external temperature which helps protect the contents in cold weather.

Greenhouses range from small sheds to huge commercial buildings. A small greenhouse is often built in a yard or garden and also known as a cold frame. On the other hand, an industrial-sized structure is used as a high tech production facility for growing plants. The big ones are equipped with heating, cooling, lighting, screening installations, etc.
