750wMH vs. 1000wHPS

Discussion in 'Growing Marijuana Indoors' started by Red I's, Jan 12, 2003.

  1. I'm considering the purchase of a grow system that has a
    dual ballast which will provide 750wMH for the veg, and
    1000wHPS for the flowering. I will start them on fluorescent,
    and then start them on the MH in a 4x6x10high grow room.
    Is the MH going to make that much difference in the grow
    cycle? Or can I just use the fluoros until they get 12" and
    then go straight to the HPS to continue the veg?
    Any thoughts would be appreciated.
  2. If you already hav your MH and HPS lights handy, then use MH for veg and HPS for flowering. Otherwise depends if you can afford them etc. How many plants you growing?
  3. I've got 30 started but figuring the male/female ratio I
    hope to end up with at least 15 or more. I know the 750MH
    is only going to provide 31w per sq. ft., but I think that should be enough?
