Terracotta Clay Pot With Glass Reservoir, 6 Inch Self Watering, And Flowers [Self Watering] Because of high water permeability, terra cotta has been used as an irrigation tool since ancient times. When it comes to this carefully designed Phoenix Vine self watering planter, the inner unglazed terracotta pot simply soaks up water from the glass reservoir and slowly releases it into the soil. [Easy to Refill] The outer glass vase allows excess water to be stored at the bottom. Fill in about 1/3 of water at once, and you are free to go! Your plants will thrive for at least 10 days without daily care. Through a clear view you know when it is time to refill the reservoir. Forget about under / over watering, as just the right amount of moisture will be delivered to the plant roots. [Dimension] 6.0'' Outer diameter (4.7'' Inner diameter) 6.5'' Height.
