No repotting! Simply insert the supplied LECHUZA wicks into the bottom of three store-bought grow pots, up to 4-1/2 inches in diameter. Drop the grow pots into the LECHUZA Balconissima Color planter and fill the reservoir with water. Users can easily monitor the water reservoir level with the planter’s water-level indicator, which shows when the reservoir needs to be refilled, taking the guesswork out of plant care and extending time between watering. Includes 2 brackets for hanging over railing. The attractive Cube Color Triple complements every decor. The CUBE Color Triple can be used to create a Green Wall with the CUBE Glossy Accessories available seperatly.
