Hey guys, I have a 400W HPS w/blue spetrum on my 20 seedlings right now. It is positioned 2.5 feet away from the babies, which all have opened and are green, each around 2 inches, roots are coming along. I was planning on getting a 400 MH from a friend but it fell through, this was the next best thing I had, I am going to Veg for a few weeks and move to a 1000W HPS for flowering. Anyways, my questions is..... Is that too much light for these girls? Am I at the right distance away? Thanks for the help.
