The Power Plant Metal Halide retro-fit lamps run off High Pressure Sodium control gear, and are ideal for vigorous vegative growth.
There is now no need to have two different ballasts, simply use the PowerPlant Metal Halide Retro lamp during vegative growth, and change to the PowerPlant Super HPS for flowering, all using the same HPS ballast. This allows the grower to give the plants the perfect Grow (blue) spectrums and Bloom (red) spectrums for optimum plant growth, more compact plant structure and amazing high yields, while only needing one ballast.
- Available in 400 watt and 600 watt models for use with all 400 watt & 600 watt HPS Ballasts.
