How does a self watering planter work?

You can make your planter self water using this method. Note that self watering planters don’t water by themselves but help prolong the frequency of manually watering the plants by providing a moisture source. Self watering systems can be made on a smaller scale indoors or on a larger scale for outdoor gardens as well.

The basic concept behind self watering is a water reservoir and a connector that acts as a portal between water and roots. The reservoir is normally located at the bottom of the container. Note that if you live in a hot climate region, you will have to reduce the loss of water by evaporation. The connector can be any material that observes water such as a wick, string, fabric, or sponge.

A soil foot system will encourage plant roots to seep water from the bottom when needed. One end of the wick is submerged in water and the other is in the soil. The wick system acts as a capillary action system allowing water to travel into the planter. You will have to refill the water reservoir as required.
