Distance of Light

  1. Hi

    I've got a 600w HPS lamp with reflector.

    Could anybody tell me what distance it should be from my seedlings (1 week old)

    Cheers
     
  2. better with just small fluros at this stage, but if you HAVE to use the 600, better keep it over 3 feet away...........it's usually 4" per 100w.........but it's young, so just be carefull........Peace out............Sid
     
  3. Cheers Sid, nice one
