  1. hey guys, im looking to add another 400 watt light to my 600 watt hps but im unsure whether i want to go with another hps or buy a metal halide to get a more even spectrum..what do you guys think? this is my flowering chamber, i veg under t5 fluorescents.
  2. If it's flowering only, then definitely HPS.
  3. well, nobody had anything good to say about a full spectrum effect, so another 400 watt hps it is!:smoke:
