Premium Multi-Span Film Tunnel Greenhouse for Advanced Cultivation
High-strength UV-resistant polyethylene film ensures 98% light transmission and 5+ years of durability, optimized for extreme weather. Modular galvanized steel frame with anti-corrosion coating supports 40kg/m² snow load, enabling large-span designs up to 8m for unrestricted crop access. Precision-engineered ventilation system (dual side-roll vents + roof windows) maintains 0.3m/s airflow, ideal for temperature-sensitive hydroponic lettuce/herb production. Multi-functional design supports soilless media (coco coir/perlite) and hydroponic systems (NFT/DWC), with reinforced anchor points for irrigation pipelines. Commercial-grade 800g/sqm woven ground cover included, preventing weeds in organic strawberry/berry tunnel farming operations. Quick-assembly boltless connectors reduce installation time by 60% compared to traditional greenhouses, perfect for contract growers expanding operations. FDA-compliant materials ensure food safety for export-oriented microgreen and medicinal herb cultivation under CE/ISO certifications.
