What Are Covers For Greenhouses

A greenhouse cover is a unique material used to cover a greenhouse, thus separating the inside environment from the outside. Often overlooked, a proper cover is a vital greenhouse accessory. There are also different types of covers for greenhouses. 

While all covers for greenhouses allow sunlight into the greenhouse, the covers are available in different materials, sizes, and shapes. 

Glass is the traditional cover for greenhouses. Glass allows plenty of sunlight and is durable because ultraviolet light does not cause it to disintegrate.

Polythene greenhouse covers are also trendy, especially among more miniature greenhouses and home gardeners. A polythene greenhouse shade cloth can have a double or single film layer and is ideal as a mini greenhouse cover.

A plastic greenhouse cover is a good compromise between polythene and glass covers in durability and cost. Greenhouse plastic sheeting is more durable than polythene and cheaper than glass.  

Are Greenhouse Covers Worth It?

Covers are critical components of any greenhouse because they influence the quality and level of light your plants receive.

The suitable sheeting for a greenhouse will diffuse lighting, offering better light quality for the plants than direct light. Such light will increase the production yield in plants. A greenhouse cover is also crucial to retaining heat within the greenhouse. 

Covers for greenhouses stabilize the environment within the structure by buffering the optimal temperature, light, humidity, and moisture. A greenhouse without the ideal cover may fail to provide a suitable environment for plants growth.
