This powerful 15W grow light with E27 socket is perfect for growing a plant in a Botanium. With a broad light spectrum well suited for plants, the hue is still neutral and white - unlike many other grow lights that emit pink and often unpleasant hues. Thanks to highly efficient LED technology you can grow your plants throughout the year - regardless of how much natural light you get by from your window. We recommend putting in on a timer so that it is on for 15 hours and off for 9 hours everyday.
