What is a Self-Watering Pot?

A self-watering pot is a pot or planter that supplies water to plants by means of a built-in water reservoir. They provide a convenient way to ensure plants get enough water for optimal growth, without worrying about regular watering.

How Self-Watering Pots Work

Self-watering pots work by allowing a certain amount of water to pass through the soil into the reservoir at the bottom. The plants draw the water up from the reservoir whenever they need it.

Here is a quick overview of how self-watering pots function:

  • The bottom of the pot is designed so wicking material such as hydro-wool runs through the entire length of the pot to the water reservoir.
  • A water reservoir is filled with liquid nutrient solution and placed at the very bottom of the container, allowing water to be drawn up from the reservoir as needed.
  • A float valve at the top of the reservoir serves as a “check valve,” allowing the nutrient solution to flow out into the soil, and prevents back-flow.
  • As the water in the reservoir is depleted, it is refilled, either manually or through a self-filling unit.

Self-watering pots make it easy to maintain healthy plants by making sure they are getting the right amount of water. They are a great option for busy households, or for anyone looking for a practical and efficient way to water their plants.
