Product Description
The semi-closed greenhouse is mainly composed of Q235 hot-dip galvanized steel frame and aluminum alloy gutter, with outstanding wind and snow resistance and an aging life of over 20 years. The covering layer is made of high transmittance diffuse glass, which converts the light into scattered light and evenly illuminates the plants, improving photosynthetic efficiency and enhancing fruit quality. The built-in FCU intelligent climate system can achieve multi parameter linkage regulation, taking into account functions such as heating, cooling, dehumidification, and carbon replenishment, effectively reducing heating and cooling costs while maintaining environmental stability. Strengthening the synergistic effect of insect proof nets and semi closed structures significantly reduces the risk of pest and disease invasion and dependence on chemical pesticides. The system reserves expansion interfaces such as water and fertilizer integration, LED fill light, atomization humidification, and remote management of the Internet of Things, supporting the annual continuous production of multiple categories of crops such as leafy vegetables, fruit vegetables, strawberries, and herbs. It provides a high-yield, low-energy, and safe all-weather planting solution for commercial farms in extreme climate areas.

Product Advantages
1
The greenhouse skeleton is made of Q235 hot-dip galvanized steel and matched with aluminum alloy gutters, which have high weather resistance and deformation resistance, and can easily cope with wind, snow, impact and corrosive environments. After fatigue verification, the structural system remains stable and reliable throughout its entire life cycle, with a service life of over 20 years.
2
Using diffuse tempered glass with a transmittance of ≥ 91.5% as the lighting surface, the light is soft and evenly distributed, avoiding leaves and fruits from being burned by strong light, while enhancing photosynthesis in the middle and lower layers of the plant. This lighting environment can significantly improve crop uniformity and soluble solids content, achieving a dual gain in yield and quality.
3
After selecting water and fertilizer integration, LED lighting, carbon dioxide supplementation, high-pressure mist spraying humidification, and IoT remote control components, the greenhouse can automatically perform irrigation, fertilization, dimming, humidification and other operations based on crop growth models, with minimal manual intervention, achieving all-weather unmanned precision planting.
4
90% self-produced rate, CE certification, 15 patents, strict three inspection system, zero defects at the factory.Support third-party detection.
5
We provide customized services for climate data collection, structural strength verification, foundation design, environmental control selection, irrigation schemes, and supplementary lighting systems at the project site. We also provide installation drawings and engineer installation guidance.

Application and Solutions
Extremely cold in winter，conventional greenhouse vegetable crops will experience irreversible freezing damage.
Double-layer insulation
Cooling scheme
Light exposure
Snow collapse
Temperature regulation
Lifespan
Double-layer insulation
Winter extreme cold climate, vegetables freeze to death
The combination scheme of FCU closed-loop heating and double-layer insulation curtain is adopted to accurately control the temperature inside the greenhouse above the critical value of 10 ℃. This configuration effectively blocks cold stress, avoids crop tissue frostbite and root inactivation, ensures no dead seedlings throughout the entire growth period, and achieves safe winter production.
