Use the Sandalwood 150W Dual Mode LED Grow Light to promote plant growth in areas of partial or no sunlight. This 150W Dual Mode LED Grow Light is ideal for a variety of horticultural activities such as indoor gardening, plant propagation, and food production, including hydroponics and aquatic plants. The Sandalwood grow light is specially designed to provide the appropriate LED spectrum at all stages of your plant's growth cycle. Turn the left Grow switch on in the early stages of your plant's growth and 75W of lamp power aid in the photosynthesis process. Turn on both the Grow and Bloom switches during your plant's main growth stage to activate the full 150W of power. Toward the end of your plant's growth stage turn on the right Bloom switch to apply the appropriate spectrum. The Sandalwood grow light is also cost effective by providing high luminosity with low power consumption.
