7000k bulb

what are the pro's and con's as to using a blue mh bulb with a 7000k color temp for veg ??

Ok this is an awesome color spectrum for seedling and veg growth for sure. The pros are; The plant produces excellent leaf and stem growth. Cons; Its not a spectrum to use for flowering, you need to change to HPS 2200k when that time comes. But no for the first three to five weeks thats the spectrum bulb you want for those first three to five weeks, Then when you flower you are going to have a heavier set plant with enriched leaves and fat stems. But when the buds start popping up then you should deffinitely change to the red orange spectrum 2200k, with a HPS bulb, cuz that will make the buds grow dense, plentiful, and much larger, + the Crystal production just explodes with that set up. But as a product of using MH and HPS is that you get a much better yeild.

sweet thanks.
