This article presents an innovative modular planting plant factory inspired by lean manufacturing principle, where planting cells work in a distributed way, coordinated by cloud service. Each planting cell is equipped with controllable light source, CO 2 supplement and fans. All cells are remotely and locally controllable, including instructions on environmental adjustment and planting task scheduling. This system offers flexibility, scalability, and autonomous management of plant factories. Preliminary results indicate its potential in precision agriculture. The modular system adapts to diverse scenarios, focusing on robustness in smart factories and user-friendliness. It envisions urban cultivation as a social platform and aligns with emerging trends in cyber-physical social systems (CPSS) and Distributed Autonomous Organization (DAO). This work represents a convergence of technology, adaptability, and a vision for interactive urban agriculture.
