Harness the power of the sun with Hortilux Blue. These metal halide grow lamps are designed to produce high quality, healthy looking plants during all phases of vegetative growth. Research shows that spectral energy ratios are more significant than lumens for plant growth. The exclusive chemistry in these bulbs provides ratios of red, blue and green spectral energy that better meet the needs of plants compared to standard halides.
