i have seen Mh bulbs up to 12,000k, and that is a very very blue light, anyone every try and grow with one? would it work alone? how would it work with a 6400k? was just wondering

I have a transition bulb I use 3200k for veg n transition lol. Love the thing n would have to say it out performs my 5600k mh by far.
Really hard to say IMO how well it would work alone n I'm noticing more n more t5's n vegging bulbs are introducing more colors into them.
Hope this helps some
