Solarmax 400 W MH Veg Lamp (12/Cs) (902820)

In younger plants it is blue light that is the most crucial. The SolarMax™ Veg Metal Halide bulb delivers 30% more blue light than standard bulbs. The result is stronger roots during crucial early stages of development and more vigorous, vegetative growth throughout the plant's life. They are universal bulbs, which means that they can be burned horizontally or vertically.
