After that haircut it's good to see the comeback.
If plasma has the full spectrum of light, why would you need HPS for red?
Plasma is a good looking light with a high CRI but at 60 lumens per watt it is not an energy efficient light by any means. All you have to do is check out the
Photopic Lumen values on page 6 of the technical comparisons and you'll see that this is a lamp designed with 73% of it's energy being emitted in the visual regions. If you plan on flowering with a plasma you have to add a R-FR source which is what Gavita recommends with their dual end 1000 watt HPS lamps to run in concert with the plasma.

When considering the price of a plasma setup, I don't know how plasma is in business for any application, much less gardening, when there are more efficient/affordable technologies, require less moving parts and deliver plant spectrum's evenly across the canopy that one could choose from. Just my .02 centavos
