The main difference between an indoor and outdoor garden is control. Indoor gardens grow plants in a controlled environment, while outdoor gardens depend on natural sunlight, weather, and seasons.

In an indoor garden, light, water, and temperature are managed by the grower or by a system. Smart gardens go one step further by automating these factors, using built-in lighting, watering, and sometimes app-based controls to keep conditions stable.

Outdoor gardens rely on soil quality, rainfall, sun exposure, and seasonal changes. This allows plants to grow naturally but also makes results less predictable, especially in colder climates or small living spaces.

In everyday use, indoor and smart gardens offer consistency and convenience, while outdoor gardens offer scale and natural conditions.
