Yes, many modern self-watering urban planter boxes include a practical water level indicator to show when the reservoir is low. This feature typically consists of a simple visual gauge or float mechanism that rises and falls with the water level, allowing you to monitor moisture reserves at a glance. When the indicator shows low levels, it's time to refill the reservoir to ensure your plants receive consistent hydration. This smart design eliminates guesswork, prevents overwatering or underwatering, and supports healthy plant growth with minimal maintenance—perfect for busy urban gardeners seeking efficient gardening solutions.
