  1. My reflector is like a dome,so how many inches do i want the light bulb away from the plants?
     
  2. what kind of bulb? if it is a compact flourescent leave it about 4 inches away they do tend to get a little warm but not a bad as an HPS or MH if it is either one of those i would say 10-12 inches depending on your ventilation.
     
  3. 1cm per every 10 watts of the light. 250 watt light = 25 cm seperation.
