Sorry I thought I read HPS. I don't think HID has the correct spectrum for photosynthesis, are you talking Quartz, HPS or MH?. Google that and find out. Quartz is the one that dosen't grow plants
I have used High Pressure Sodium 250watt, 600watt, Metal Halide 250watt, Fluorescent t8's,and LED.
LED is by far the winner for my size area.
