i got a 400w hps light here with the ballast in the light fixture. all inclosed just a box with glass on the bottom for light to travel out. i have a 12" fan that i am goin to point directly on it and turn high speed to keep it cool. i have a few plants flowering and am wondering a general distance i should keep them without burning them or stretching them to much. thanks
