I was wondering whats the ideal height for the lights to be at away from the tops and im asking for each type of bulb, 400,600,1000 watt and is there a difference between vegging and flowering, should i be close, far away
You want to be as close as you can. Hang your light and bring it down until it is as close as you can without feeling to hot on the back of your hand just above the plants.
