The climate screen solution has provided us with a much more controlled environment. We see less temperature variation between day and night, which helps both plant health and energy use.

At Lanzhou Nongtou, a greenhouse grower in China, managing energy use and creating a stable growing climate are essential to year-round production. To achieve both, the team installed climate screens designed to reduce heat loss and improve environmental control.
These screens have helped the growers balance light, temperature, and energy conservation across the greenhouse, contributing to a more consistent growing environment throughout the season.
Climate challenge and solution
The greenhouses at Lanzhou Nongtou are located in an area with wide temperature swings and strong solar radiation. During the day, high levels of light and heat can stress the crop, while at night, low temperatures increase energy demand. The growers recognised the need for a climate control strategy that could address these extremes.
To achieve this, they installed a climate screen system that combines energy-saving properties with controlled ventilation and light diffusion capabilities. The screens help to:
Reduce heat loss during night and cold periods
Smooth out peaks in solar radiation during the day
Create a more homogeneous climate around the plants
By improving energy retention while still allowing light transmission, the climate screens support growth without unnecessarily increasing energy costs.
Grower experience
According to the team at Lanzhou Nongtou, the screens have delivered measurable benefits since installation. The growers report that their greenhouse environment has become more stable, with fewer temperature fluctuations and improved energy efficiency.
“The climate screen solution has provided us with a much more controlled environment,” says one of the growers. “We see less temperature variation between day and night, which helps both plant health and energy use.” The growers also noted that the improved environmental control has simplified some aspects of daily climate management, allowing them to focus more on cultivation tasks rather than constantly adjusting the greenhouse settings.
Impact on production
By creating a more controlled climate and reducing energy use, Lanzhou Nongtou has been able to support more stable crop performance throughout the growing cycle. The enhanced environment has helped maintain uniform plant development and reduce stress caused by extreme temperatures and fluctuating conditions.
This focus on climate control and energy saving has contributed to greater confidence in year-round production and helped the growers manage both variable weather and high operational costs.
