DIY Grow-Light System Tracks Plant Growth

A maker named Bubs built a motorized grow-light system that keeps an LED array focused on the top of a plant as it grows. He combines red/blue LEDs with optical lenses, a Python light simulator, PCBWay SLM aluminum 3D-printed heatsink mounts, ESP32-driven drivers, and a motorized winch to adjust height and schedule intensity. The design enables energy-efficient indoor lighting and future sensor automation.
