I am flowering with a 600 W hps hung vertically with no reflector. I find hanging the light vertically takes up more ground space but gives prime use of the bulb in all 360 degrees creating a several times greater prime light volume. By prime light I mean the intense light close to the bulb.
If you want maximum effecincy per bulb go with a Vertically hanging light, but if you want greater efficiency per ground area go horizontal.
I want to know if anyone else is using vertical 600s with no cool tube and how far from the light do you put the plants. Right now I have them at about 2 feet and the leaves seem to be twisting a bit.
