Side by Side 400W

  1. I'm wondering if anyone has any experience running 400w MH and 400w HPS side by side?

    I have a 400w hps and its great but my gf just got her 215 also and we're upping the op 12 total (in 3 gallon pots). I figure two hps would be fine but I'm thinking the extra spectrum coverage will give me better results (not that my results aren't good already;)).

    Any input would be great!! I'm excited to get this done.
  2. Works well. I tend to think that a mixed spectrum is to be preferred, but I have no empirical evidence. It's certainly no handicap.

  3. Get a Mh/HPS converting system. Veg with One of each, Flower with 2 HPS bulbs.

  4. I don't veg.

    Asking strictly about flowering, I've considered the 2x HPS but I was just wondering about the side by side and the spectrum difference. Thanks though.
