MH or HPS for Veg

Discussion in 'Growing Marijuana Indoors' started by AGGrower, Mar 12, 2011.

  1. I was always told that MH is the light to use for vegging and I met a guy who said HPS is better for vegging. Is this true?
     
  2. Personally I also like HPS better for veg (as long as it's the blue spectrum enhanced HPS bulbs), but the vast majority will tell you that MH is better.
     
  3. i grew 2 clones of a Big bud plant. One under a 150 hps and one under 150 MH.

    the hps has less bud but the buds were way thicker.

    the MH had about 8 inchs of x-tra plant and bud.
     
  4. hps all the way though grow cycles like the man said little more blue spectrum but also hear good things about dual arc bulbs
     
  5. MH durring veg HPS durring flower. MH emits more blue spectrum light which the plants want durring veg and HPS more red that they want durring flower. HPS tends to produce far more dense buds as well.
     
  6. im vegging under hps with a standard bulb right now, and they are looking great, nice and dense, no stretching, although i wish i did pay a little extra for the enhanced spectrum bulbs, im sure they would be growing a little faster.
