    FAQ

    1
    What types of crops and uses is the Sainpoly polycarbonate greenhouse (9.6/10.8/12m span, 4m bay) best suited for?
    This greenhouse is versatile — ideal for commercial vegetable production (tomatoes, cucumbers, peppers, leafy greens), nursery propagation of ornamentals and seedlings, floriculture, and protected fruit production. It also works well for hydroponics, aquaponics, research plots, and seasonal extension for hobby growers.
    2
    How do I choose between the 9.6m, 10.8m, and 12m span options?
    Choose a span based on space, workflow and equipment needs: wider spans (10.8m, 12m) provide more unobstructed production area and easier mechanization, while narrower spans (9.6m) can be cheaper and easier to heat/ventilate. Consider site access, crop layout, and whether you need room for internal aisles, trolleys or irrigation lines when selecting a span.
    3
    What does "4m bay" mean and how do bays affect installation and expansion?
    A 4m bay means the greenhouse is modular in 4-metre sections along its length. You can start with a few bays and add more to expand production linearly, giving predictable expansion costs and simplified assembly. Bays also make it easy to plan irrigation, lighting and zoning for climate control.
    4
    Can this greenhouse be used year-round and in cold or windy climates?
    Yes — with appropriate foundation, anchoring, insulation and heating, the polycarbonate structure can be used year-round. The twin- or multiwall polycarbonate panels provide light diffusion and thermal insulation compared to single glass. For safe use in high wind or heavy snow regions, specify site-engineered anchoring and roof load ratings with your supplier and add reinforcements, snow guards or heating as recommended.
    5
    What climate control and accessory options work well with this greenhouse for commercial use?
    Common options include ridge and side ventilation, exhaust fans, circulation fans, evaporative cooling or shading screens, automated vents and climate controllers, drip or ebb-and-flow irrigation, fertigation lines, LED supplemental lighting and benching or gutter systems. The frame accommodates automation and utilities; plan wiring, piping and sensor routes during installation.
    6
    What are the basic installation, foundation and maintenance considerations for long service life?
    Install on a level site with a stable foundation — concrete footings, perimeter strip footing or ground anchors as recommended by your dealer. Anchor frames securely and seal panels to prevent water entry. Regular maintenance includes cleaning panels, checking and retightening fasteners, inspecting seals and gutters, and clearing snow. Follow supplier assembly instructions and have an engineer review plans for extreme-site conditions.
