Where embedded systems meet living roots<\/h2>\n<\/blockquote>\n<\/div>\n\n\n\n

What started as a simple idea – a living wall instead of a bare surface – quickly became something more complex: a self-regulating ecosystem spanning
2.44 \u00d7 0.9\u00a0meters, distinct moisture zones, and more firmware iterations than I care to admit.<\/p>\n\n\n\n

This wall runs on a closed nutrient loop, LED lighting, and an ESP32 controller I built and programmed myself. It waters on a schedule, and can be updated over the air. The plants, however, still do whatever they want.

This site documents the build – the engineering decisions, the horticultural experiments, the bugs (software and biological), and whatever comes next.<\/p>\n\n\n\n

Everything is a work in progress. That’s the point.<\/strong><\/p>\n\n\n\n
