The Power Plant Metal Halide retro-fit lamps run off High Pressure Sodium control gear, and are ideal for vigorous vegetative growth. There is now no need to have two different ballasts, simply use the Power Plant Metal Halide Retro lamp during vegetative growth, and change to the Power Plant super HPS for flowering, all using the same HPS ballast. This allows the grower to give the plants the perfect Grow (blue) spectrum’s and Bloom (red) spectrum’s for optimum plant growth, more company plant structure and amazing high yields.
