PowerPlant 400w Metal Halide

The Powerplant Metal Halide Super Veg Bulbs are designed for the vegetative growth phase of plants. During the vegetative growth phase plants prefer blue spectrum light, which these bulbs emit. The benefit of metal-halide lamps is that plants do not stretch as much and instead remain shorter and develop more shoots.

Metal halide bulbs are used with the same equipment as your main sodium flowering light, when your plant has reached its flowering stage simply swap over to a HPS bulb. Remember to use the same wattage as your sodium light though.
