To set up an indoor herb garden in a kitchen alcove, install twelve-inch-deep shelves spaced ten to twelve inches apart vertically to allow herbs room to grow. Use full-spectrum LED grow lights rated between three thousand and four thousand Kelvin, positioned six to twelve inches above the plants, on timers for twelve to sixteen-hour cycles to mimic natural light. A matte tile backsplash protects walls, and placing a metal tray at the base catches water drips. Incorporating a nearby water source and a silent fan helps maintain airflow and prevents mildew, ensuring healthy plants like basil and mint thrive year-round.
