I have to agree with SerraAva on this one.
One room I work regularly, due to how the air moves in there, I have to place my ground fogger at the back of the stage, aimed a little bit to house right to get even coverage. I place the hazer next to it and aim it the same way. Got great coverage this way for both units.
I tried the ground fogger and hazer on stage right, but the ground fog wouldn't go far enough and the hazer was vibrating too much and inducing too much noise into the hollow stage. The back area is concrete, so no vibration noise!
Otherwise, I recommend a place OUT OF THE WAY so nobody is tripping on it.
