    Product Description

    Sainpoly's flat hydroponic greenhouse is aimed at global agricultural producers, achieving uniform distribution of light energy through flat planting beds, eliminating the electricity and maintenance costs of layered supplementary lighting, and providing intuitive and convenient operation. The greenhouse structure adopts hot-dip galvanized steel frame, which can be thickened by galvanizing or sprayed with plastic treatment, with a service life of 15-20 years. Through actual testing, it has maintained stable operation under conditions of -35 ℃ severe cold, 1.5 meters of snow cover, 12 level strong winds, and 50 ℃ high temperature, achieving uninterrupted production and income throughout the year.


    The hydroponic process supports NFT shallow flow and DWC deep water cultivation, suitable for annual production of crops such as leafy vegetables, strawberries, herbs, tomatoes, etc., while meeting the needs of seedling cultivation, agricultural parks, and scientific research projects. The source factory of Shengbaoli supports full-size customization, providing one-stop delivery from design, production to installation and commissioning. After user acceptance, it can be put into production.

    Product Advantages

    1
    Sainpoly's flat hydroponic greenhouse is used for the commercial annual planting of crops, with a built-in circular hydroponic system 11 Extreme cold insulation
    The flat hydroponic greenhouse is equipped with a three-layer composite insulation screen of Oxford cloth, spray bonded cotton, and Oxford cloth. A static air layer is formed behind the screen at night, and the measured heat transfer coefficient is about 40% lower than that of a single-layer film, effectively suppressing radiation heat transfer and cold air infiltration heat loss, and maintaining stable temperature inside the greenhouse.
    2
    Sainpoly's flat hydroponic greenhouse is used for the commercial annual planting of crops, with a built-in circular hydroponic system 12 High transmittance
    The covering material of the flat hydroponic greenhouse has a full band light transmittance of not less than 91%, providing sufficient light quantum flux for photosynthesis. The surface can be optionally equipped with a diffuse scattering coating to convert incident direct light into a multi-directional diffuse light field, eliminating the risk of local light burns to leaves and fruits, while improving the uniformity of light distribution within the group.
    3
    Sainpoly's flat hydroponic greenhouse is used for the commercial annual planting of crops, with a built-in circular hydroponic system 13 Intelligent environment control

    Avoid freezing

    The decrease in winter temperature leads to the freezing and death of vegetables.

    Adopting a double-layer hollow covering scheme (optional glass, solar panel or inflatable membrane), the measured heat loss is reduced by 50% compared to a single-layer one. The inner side is equipped with Oxford cloth composite insulation screen, which can be upgraded to folding insulation quilt or double-layer inflatable membrane structure. Reserved heating system interface and zone temperature control circuit for greenhouse. Effectively prevent root metabolism decline and plant freezing induced by low temperature, ensuring stable overwintering and production of the flat hydroponic system.

    FAQ

    1
    Q: What hydroponic modes are supported for flat hydroponics?
    A: Support two mainstream modes: NFT (Nutrient Membrane Technology) - nutrient solution forms a thin layer of flow in the planting tank, suitable for leafy vegetables; DWC (deep flow technology) - soaking roots in nutrient solution, suitable for fruits and vegetables. It can be flexibly selected or combined according to crop types.
    2
    Q: What crops are suitable for flat hydroponic cultivation?
    A: Suitable for leafy vegetables (lettuce, spinach, bok choy), strawberries, herbs (basil, mint), tomatoes, peppers, etc. It is also commonly used for seedling cultivation, scientific research demonstration, and agricultural park projects. Compared to vertical hydroponics, the flat planting mode is more suitable for crops with larger plant types and requiring more growth space.
    3
    Q: Do you offer installation services? Is remote guidance available?
    A: We offer two service modes: ① On-side guidance by technicians dispatched from our headquarters ② Detailed installation videos,manuals,and remote technical assistance.
    4
    Q: How long can the framework of a flat hydroponic greenhouse last?
    A: The main framework is made of Q235 hot-dip galvanized steel, with the galvanized layer ≥ 40 μ m, corrosion resistance and aging resistance, and the design service life is more than 20 years. The hydroponic equipment such as planting beds and pipelines can be replaced separately as needed, and the main structure can be put into long-term use at once.
    5
    Q: Can Flat Hydroponic greenhouses reduce pesticide use?
    A: Okay. Hydroponic cultivation does not require soil and can effectively avoid soil borne diseases such as root rot and nematodes. By cooperating with insect nets, positive pressure ventilation, and disinfection buffer rooms, the incidence of pests and diseases has been significantly reduced, and the use of pesticides has decreased by more than 70% compared to soil cultivation.
    6
    Q: Does your Flat Hydroponic greenhouse comply with EU standards?
    A: Yes. Our Flat Hydroponic greenhouses are CE-certified, and all materials including steel, glass and sealant fully comply with relevant EU standards. We can assist customers in passing local acceptance inspections.
