What is the function of a greenhouse cover?

The function of a greenhouse cover is primarily to provide insulation and light transmission. A greenhouse is designed to create an optimal growing environment for plants by using transparent materials, such as glass or plastic, that allow sunlight to penetrate while also helping to retain heat. This light is essential for photosynthesis, the process by which plants convert light energy into chemical energy to fuel their growth.

The insulation aspect is equally important, as the greenhouse cover helps maintain a stable temperature inside, protecting plants from external temperature fluctuations. This controlled environment can enhance plant growth, promote early blooming, and increase productivity. In essence, the right greenhouse cover balances light entry and heat retention, creating an ideal microclimate for cultivating a variety of plants throughout the year.
