<p>The present invention relates to an unpowered automatic water supply device responding to a soil water content ratio change, the device comprising: a water tank having a water supply tube through which water is supplied from the outside; a container support communicating with the interior of the water tank via a connection tube; and a container in which flowers are planted, the container being seated on the upper portion of the container support, an injection opening being formed on the bottom surface of the container such that water flows in, wherein water flowing to the connection tube is adjusted and then supplied into the container through the injection opening. The supply of water to the container can be advantageously interrupted in response to the weight of soil contained inside the container.</p> |
