    yo which is better overall? to have a dual spectrum light for the whole grow or a metal halide for veg and a hps for flowering? 

     
  2. I have never run the dual spectrum bulb, however, I use both MH and HPS during 
    the flowering period with results that I am very happy with. There seem to be
    more trichomes when the MH was used in addition to the HPS.
