What Is Greenhouse Gardening?

A greenhouse (also called a glasshouse) is particularly designed to grow and protect tender or out-of-season plants against unfavorable and harsh weather conditions (frost or excessive heat).

A greenhouse is a small building or structure in which plants are grown. Depending on your needs, these buildings can be small (also called cold frames) structures or quite large commercial-sized (also called hothouses).

The idea behind greenhouses started back in Roman times when Emperor Tiberius demanded to consume an Armenian cucumber every day. Hence, gardeners had to use a system identical to modern greenhouses to ensure Emperor had cucumber day.

A modern greenhouse garden is generally made of glass or plastic with a minimalist frame and designed to maximize natural light.

The natural light allows the plants to photosynthesize and grow, which keeps the greenhouse garden a few degrees warmer than outside.

In addition, the glass or plastic walls and roof capture the sunlight’s warmth and energy; this is particularly important during cold winter weather and overnight.

According to research conducted by Leslie Forero from Utah State University, issued in Frontiers in Environmental Science, the way plants and soils behave inside a greenhouse may differ from how plants and soils behave outdoors.
