Lighting question

  1. so I purchased a 400w hps me light with ballast as shown below

    Now what I'm wondering is how to use it with my seeds. I purchased autoflowering GDP seeds and I was wondering if I could use this light the whole way through or should I get a different light for while they are in the veg stage
  2. Read everything in the website below then come back to grasscity with followup questions...
