Watering Duration Calculator: Personalized Daily Irrigation Plans for Your Plants

Tips: Do not know the area of your watering area? Use our online measuring tool to calculate your watering area of your garden on a map or a picture.

Tips: Open the tap to the ideal flow rate, then fill a water bottle with a volume scale. The water bottle capacity (liters) divided by the time for filling the bottle (seconds) is the Water Flow Rate (Liter per Second)

Watering Duration Calculator: Personalized Daily Irrigation Plans for Your Plants

Welcome to the Smart Watering Duration Calculator — an intelligent irrigation planning tool designed for home gardeners and small-scale growers. By entering key information such as your plant type, garden location, soil type, watering system flow rate, and garden area, this tool provides:


  • Recommended daily watering duration (How long to water, in minutes, per 24 hours)
  • Estimated watering volume for the next 7 days, based on real-time weather forecast including rainfall and humidity

This calculator is fully compatible with popular automatic irrigation controllers such as RAINPOINT, Orbit, Eve Aqua, and more. Even if you water manually, the tool gives you precise daily volume recommendations based on scientific calculations, not just generic rules of thumb.


  1. Plant-specific water requirements: Every plant (e.g., citrus, tomatoes, lavender) has its own ideal soil moisture range
  2. Weather-aware adjustments: We analyze 7-day forecasts for your exact location, including precipitation, humidity, temperature, and more
  3. Soil water retention modeling: Irrigation needs are adapted based on whether your soil is loamy, sandy, or clay-heavy

Our engine then converts these insights into precise watering amount and watering duration based on your device’s flow rate (L/s), ensuring efficient watering without overuse or under-supply.


Example: For a 100 m² garden using a 0.2 Liter/Second hose and growing citrus plants, you might receive results like:

  • Today's recommended watering time: 10 minutes
  • Daily volume needed: 100 liters
  • Which days need watering plants, and which days not.

This tool works globally and is 100% free to use. It is ideal for hobby gardeners, balcony growers, and smart garden planners.
