The PowerPlant Metal Halide SuperVeg (also knownas retro-fit) lamps run off High Pressure Sodium control gear, and are idealfor vigorous vegetative growth.

There is no need to have two different ballasts, simply usethe SuperVeg lamp during vegetative growth, and change to the PowerPlant SuperHPS lamp for flowering, all using the same HPS ballast.

This allows the grower to give the plants the perfectGrow spectrums and Bloom spectrums for optimum plant growth, morecompact plant structure and amazing high yields, while only needing oneballast.
