I am getting a 1000 watt HPS for three plants. I want to know a few things. What light should I use for the first 2 weeks after she sprouts? Because I know if I use that 1000 watt it will burn up the seedlings. After the first two weeks, I will switch to HPS. How far away should I generally keep it? Also I one last thing, with the 1000 watt should I leave it on 24 hours or do a 18-6 for vegetative?
