Sustainable Lettuce Production in Controlled Environments

Sustainable Lettuce Production in Controlled Environments   Lettuce greenhouse are custom-designed for leafy lettuce (loose-leaf lettuce, head lettuce, romaine lettuce, etc.), featuring a cool, humid, well-ventilated environment with diffused low light. This is ideal for lettuce's preference for cool temperatures, intolerance to strong sunlight, and shallow root system prone to rot. They typically utilize multi-span film/PC polycarbonate sheet structures, combined with hydroponics/substrate cultivation systems. These green house are core facilities for large-scale fresh lettuce cultivation and direct-supply lettuce bases to supermarkets, and are widely used in leafy lettuce industrial parks throughout China.   Design Highlights:   1. Precise Temperature and Light Control: Equipped with external shading (30%-50% shading rate) and an internal diffused reflection layer, strong light is converted into soft, diffused light, preventing bolting and leaf edge scorching. The temperature con…
