How many hours do those metal halide (400 wts) users keep them on for?
Thanks,

Few thinks to remind you.
Take in consideration if use Berlin socks , Ozonizer, UV filters or your ORP is high (380-400) i mean if the water is crystal clear , may have to increase the high of MH light fix.
Is gone surprise you ......how GOOD or BAD is the light fix. ( i refer to reflector) some do 50% efficiency of the Bulb some 100%.
I like Radium 20.000 K , good grow, great color.
