Grow from start to finish with ONLY HPS?

  1. Anyone have experience with growing from start to finish with ONLY HPS lighting?

    I'd imagine the only thing you change is the nutes and light cycles.

    I'm curious to start my next grow from clones and flower early. Is it worth veg with MH lights or can I use HPS the whole way through?

    Peace.
     
  2. thats what i started off with. 600w. no problems
     
  3. You can veg with HPS and you'll have no problems...
    Yes I've grown w/ HPS only before and still do. I have MH also.
     
  4. I read that modern horticultural HPS bulbs had a wide enough spectrum to work for veg growth. My impression is that MH bulbs would be slightly better, but probably not enough to justify the extra cost and hassle.

    I'm planning to use a 600w HPS (with a horticultural Grolux bulb recommended by the guy in the grow shop) for my grow, for the record.
     
  5. It'll work but you need to be much more careful and pay closer attention. Right now I have my 600w MH about 30 inches away from the seedlings and they look like theyre doing ok.

    You'll need to keep adjusting until you can see how close you can get without burning them, but don't test it on the sprouts :smoking:
