Thanks to the stick-irrigation system, fresh plants can be placed into this planter simply and easily, including the grow pot and avoiding elaborate repotting! Inserted into the bottom of the grow pot, the irrigation stick supplies moisture to the roots evenly. The planter’s large, round eyes serve to indicate how much water is left in the reservoir, allowing children to learn to keep track of the moisture levels in their plants. If the interactive eyes are blue, this indicates that the water reservoir is full.
