what happens if you use a hps to veg?

you'll be fine..just make sure to watch the plants carefully for light burn.....
 
you may find that the plants stretch a bit more in veg with the hps
 
It works just fine but IMO adding some white light makes it better. I use 25% white 6300K and 75% HPS in terms of watts. Mixed spectrum for all stages.

I did not.

I did too. But, bigger overall, not as dense (as compared to MH).
 
Mine stretched and burned easy when young. I use t5 and MH now.
 
18/6 & 24/7

seem to stretch alot more on 18/6 though MH much better light to use in veg,for me anyway
