IMHO if you can run four and control the heat, more light=more growth. Are you going to mix hps/mh or are you gonna go straight hps?

Asking if you are going to red flag leo is like rolling dice. How big is your house? Are you a renter? What is the electrical history like? I would think that a 10K watt surge in use without the square footage to justify it is a possibility of getting on radar. In other words, too many variables for us to predict for you, but follow your gut. If you are in a medical state, you should look into going legal with it so you don't have to sweat.
