The Smart & Green Tango Bluetooth LED Planter is a big, bright and colorful way to house a plant and accessorize your indoor or outdoor space. It is nearly 4 feet tall, with a deep recess for planting large plants. Inside the tough polyethylene vessel, a bright color-changing LED lights up that plant and the area all around it. To change the color, dimming, scheduling and even have multiple products communicate with each other, simply download the Smart and Green app. Using Bluetooth mesh technology without a WiFi network, you can control various scene modes from your own smartphone.
