Product Description
Special Hydroponic Greenhouse for Industrialized NFT Leafy Vegetables
SAINPOLY hydroponic greenhouses are engineered for industrial NFT leafy vegetable cultivation. The NFT Nutrient Film Technique system delivers fully automatic circulating nutrient solution supply, precisely maintaining EC and pH values within optimal ranges. Combined with accurate temperature and humidity regulation inside the greenhouse, the growth cycle of leafy greens is shortened by 30–40%, enabling 10 to 12 continuous harvests per year.
Vertical multi-layer cultivation racks boost output per floor area to 8–10 times that of conventional soil planting. Equipped with full-air intake 50-mesh insect-proof net and positive pressure filtration design, the greenhouse fundamentally blocks pests and diseases to produce pesticide-free clean leafy vegetables. Recycled nutrient solution cuts water consumption by 90% compared with traditional flood irrigation.
SAINPOLY provides full-process one-stop services including variety selection, nutrient solution formula design, customized system manufacturing, on-site installation and operational technical training.

Product Advantages
1
The main frame adopts Q235B or higher-grade steel with hot-dip galvanizing treatment, with a galvanized coating thickness ≥180g/m², far exceeding the standard for ordinary steel. A single upright column can support several tons of load; the overall structural service life exceeds 15 years with industry-leading resistance to snow load and wind uplift.
2
Precise EC/pH regulation plus automatic nutrient solution temperature control shortens the leafy vegetable growth cycle by 30–40%. 10 to 12 successive harvests are achievable yearly for far higher yield than traditional cultivation.
3
Multi-tier cultivation racks raise output per ground area to 8–10 times traditional planting, greatly improving commercial return on investment.
4
The 50-mesh insect-proof net and positive pressure filtration block pests and diseases at the source. No pesticides are required throughout the growing cycle, complying with high market standards for organic leafy greens and clean vegetables.
5
90% self-production rate for core components. Integrated design and production cover hydroponic systems, environmental control systems and greenhouse structures. The product holds CE certification and 15 patented technologies. Triple quality inspections ensure zero defects before delivery.

FAQ
1
Q: How much higher is the yield of NFT hydroponic greenhouses compared to traditional cultivation?
A: With vertical multi-layer cultivation and 10–12 continuous harvests all year round, the output per floor area reaches 8–10 times that of traditional planting.
2
Q: How is the nutrient solution managed in the NFT hydroponic system?
A: The fully automatic circulation system precisely controls EC and pH values. Sensors conduct real-time monitoring and automatic liquid replenishment. Only daily manual patrol inspection for parameter confirmation is required.
3
Q: Can the hydroponic greenhouse realize pesticide-free planting?
A: Yes. Full air intake insect-proof net and positive pressure filtration block diseases and insect pests at the source. Combined with clean production management, no pesticides are needed throughout the whole growth cycle.
4
Q: What is the water consumption of the NFT hydroponic system?
A: The nutrient solution is recycled, cutting water usage by 90% versus traditional flood irrigation. It is the most water-saving large-scale leafy vegetable production mode available currently.
5
Q: Do you provide nutrient solution formula design services?
A: Yes. Our engineers customize nutrient solution formulas and EC/pH control schemes according to crop varieties and local water quality conditions, alongside full-cycle cultivation technical training.
6
Q: What is the minimum order area?
A: There is no mandatory minimum order area. We recommend projects above 3000㎡ to amortize design and transportation costs. Negotiation is available for demonstration sample projects.
