How to Select the Right Climate Screens for Commercial Flower Greenhouses

Flower growth requires a suitable greenhouse climate. Different flower species have varying requirements for light, temperature, and humidity at different growth stages.

For example, the growth and development of flowers have specific demands for light intensity and photoperiod:

Based on light intensity, flowers can be categorized as sun-loving, neutral, and shade-loving. Anthurium, orchids, and similar varieties need to grow under low light conditions.

Photoperiod is mainly related to flower induction. Accordingly, flowers are classified as long-day, day-neutral, and short-day plants, with chrysanthemums and poinsettias being typical short-day flowers.

In addition to light, appropriate temperature and humidity are also critical for the healthy growth of flowers and the reduction of pests and diseases. Climate screens are key climate control devices in greenhouses that regulate light, temperature and humidity synergistically. Their material properties and weaving density directly determine the shading rate and energy-saving rate. How can climate screens be used to create a suitable greenhouse climate for flowers?

1. Shading and Protection Function

Summer light intensity far exceeds the requirements for flower growth. Installing suitable climate control screens can effectively regulate the light entering the greenhouse and protect the plants. Reduced light also indirectly achieves a cooling effect. External shading provides better cooling performance than internal shading, mainly because external screens block solar radiation before it enters the greenhouse, minimizing heat radiation inside.

2. Diffused Light Function

In addition to shading and protection, some climate control screens can also provide high-quality diffused light for the greenhouse. Compared with direct sunlight, diffused light is softer and more uniform. It can effectively reduce shadows cast by greenhouse structures in the production area, ensure even light distribution to flower plants, and lower the workload of growers in relocating pots.

For tall cut flowers such as roses and gerberas, diffused light can penetrate deep into the plant canopy, improving photosynthetic efficiency and thus increasing yield. Meanwhile, improved light availability for middle and lower leaves allows growers to adopt reasonable dense planting and enhance production efficiency.

Excessively strong direct sunlight causes leaf stomatal closure and reduced transpiration, resulting in higher leaf temperature. This intense direct light can easily burn tender petals and leaves, while diffused-light screens effectively protect plants from such damage.
