Product Description
SAINPOLY leafy vegetable factory solution greatly improves space utilization via multi-layer vertical cultivation racks in NFT/DFT three-dimensional hydroponic greenhouses for leafy greens. The NFT system enables nutrient solution to form a thin film flowing inside pipelines, securing the optimal balance between root respiration and nutrient uptake. The system supports fully automatic environmental monitoring; it automatically adjusts shading and supplementary lighting based on light intensity, shortening the lettuce harvesting cycle to 25–35 days and enabling year-round uninterrupted rolling production. Free from soil contact entirely, it removes risks of pathogenic bacteria and excessive heavy metals. Vegetables feature crisp, tender texture and clean roots, ready for direct supermarket sales with roots intact, extending shelf life by 3–5 days.

Product Advantages
1
The support frame adopts high-grade Q235B hot-dip galvanized steel (≥180g/m²). The hydroponic pipeline uses food-grade UV-stabilized PVC, anti-aging and corrosion-resistant, with a service life of more than 20 years.
2
With 3–5 layers of vertical cultivation, the annual output on the same land area reaches 10–15 times that of traditional open-field planting.
3
The fully enclosed water circulation system saves over 90% water compared with traditional irrigation, making it an ideal option for water-scarce regions.
4
Precise environmental control and optimized photosynthetic efficiency enable a high-frequency harvesting mode of ""one crop per month"" with fast capital turnover.
5
The production environment meets clean workshop standards, complies with green food and organic certification requirements, and all core components are patent-protected.

FAQ
1
Q: To what extent can the land use efficiency of three-dimensional hydroponic leafy vegetables reach at the highest level ？
A: With SAINPOLY customized 3–5 layer NFT (Nutrient Film Technique) vertical cultivation racks, the annual yield per unit area can reach 10–15 times that of open-field planting. Extremely high economic benefits can be achieved in urban suburbs.
2
Q: How much shorter can the growth cycle of lettuce be compared with traditional soil cultivation under NFT hydroponic systems?
A: Inside SAINPOLY fully climate-controlled greenhouses, the lettuce growth cycle is shortened to 25–30 days. 12 cycles of rolling harvesting can be realized annually, which is critical for fresh food e-commerce customers requiring stable supply.
3
Q: The vegetable roots produced by the SAINPOLY solution are very clean. What commercial value does this bring?
A: Clean root systems support “fresh sales with roots”. Vegetables can be directly packed with roots into bags, extending shelf life by 3–5 days compared with cut vegetables. Meanwhile, it eliminates labor for post-harvest cleaning and greatly lifts the terminal selling price.
4
Q: Vertical planting systems tend to rust in high-humidity environments. How does SAINPOLY address this?
A: Our vertical support system adopts dual protection: hot-dip galvanizing plus secondary electrostatic spraying. It is specially designed for the high-water-vapor environment of hydroponic systems, delivering excellent anti-corrosion performance and guaranteeing the system remains rust-free for 20 years.
5
Q: How does the SAINPOLY hydroponic solution achieve maximum water conservation?
A: The system uses fully enclosed sterile circulating filtration, with a water recycling rate of 98%. Compared with traditional flood irrigation, its water-saving rate exceeds 90%, making it ideal for regions with high water costs or scarce water resources.
6
Q: Can customers monitor the operational status of the greenhouse in real time via mobile phones?
A: Yes. We have integrated a smart agriculture APP control terminal. Wherever you are, you can view real-time greenhouse video, environmental temperature & humidity, light intensity, as well as water and fertilizer indicators, enabling unattended modern agricultural management.
