The Cube Color 14 is an easy to use, decorative and practical way to keep fresh herbs ready to use at home. Simply insert the provided wick into the bottom of the 4 to 4-1/2" round grow pot that your herbs are in. Then, place the grow pot into the Cube Planter 14; add water - done! No re-potting! The water level indicator shows you the level of the water in the reservoir so you know when to add more water. The attractive, compact planters fit perfectly on a sunny windowsill. Mix and match the color neutral liner. What a great way to give your herbs just the right amount of water to stay fresh longer! Does not include a round insert pot.
