I fired up one side of the 400W PFO metal halide ballast with a 400W 6500K Iwasaki bulb and the difference is at least twice the brightness and only half as blue. But I'm curious if there is any harm that can come from running only half of the lighting setup? There are two independent 400W ballasts in one housing each with remote cords (to the sockets) and their own power cords so it shouldn't have any effect but then I don't know...
If I should be using it I could add the other over this chamber to really have some light but I suppose should subject them to this light gradually? the lamp is about 3 feet above the plants but I may adjust it so that it's only 2 feet.
any thoughts?
