Problem
Timer-driven watering ignores what is actually growing. Different plants want different light and different soil moisture, and a fixed schedule gets both wrong.
Approach
Built a bed that classifies whichever plant is growing in it and measures temperature, humidity, and light at soil level, then closes the loop: it drives the grow lighting and runs a pump to hold moisture where that particular plant wants it.
Outcome
Watering and lighting driven by the plant and the conditions rather than the clock.
