Rose Farm
Japan
A Venlo-style PC sheet greenhouse built in an earthquake-prone region of Japan. Polycarbonate sheeting was chosen over glass for enhanced safety, durability, and thermal efficiency. After nearly 12 years of operation, the structure and pipes remain in excellent condition, though the light transmission of the PC sheets has gradually decreased over time.
