What are Self Watering Containers?
Self-watering containers, also known as self-watering planters or smart pots, are designed to provide plants with a constant supply of water. These containers typically consist of a water reservoir, a soil chamber, and a water-delivery system. The water reservoir is usually located at the bottom of the container, and it stores excess water that can be drawn up into the soil as needed. The soil chamber is where the plant’s roots grow, and it is typically separated from the water reservoir by a layer of material that allows for water uptake.
How Do Self Watering Containers Work?
Self-watering containers work by using a combination of gravity and capillary action to deliver water to the plant’s roots. As the plant uses water, the soil chamber begins to dry out, creating a suction force that draws water up from the reservoir. This process is facilitated by the material that separates the soil chamber from the water reservoir, which is typically a porous medium such as a fabric or a membrane. As the water is drawn up into the soil chamber, it is distributed to the plant’s roots, providing them with a constant supply of moisture.
