Dual spectrum vs HPS (which is better?)

  1. hi ive got a 400w hps setup was wondering if Dual spectrum would be better.
    the dual spec bulb costs more money than the hps so need to find out what dual spec is all about

    my questions are...

    1. does dual spec grow em faster or make em more healthy?
    2. does dual spec get hot?
    3. does dual spec use more power?
    4. will dual spec be safe in a MH/HPS ballast?
    5. which is brighter dual spec or hps?
    6. is dual spec worth trying?
     
  2. In general dual spectrum is better, but it depends. If you are under-delivering on overall light intensity then I think you should stick with a bulb that delivers the spectrum needed by the plant for the particular growth stage it is in (MH for veg, HPS for flower). But if you are delivering plenty of overall light then mixed-spectrum should be better for the plant.
