Hi, I'm deciding on which 400w mh bulb to get for vegetation and am not certain the difference between the various temperature grades that they are sold in. I'm guessing that I'm looking for something in the 6500k range for ultimate blue output but I've seen others past 10000k. What's the difference? Thanks!

Ps. Would welcome any recommendations on specific brand.

I use an UltraSun Blue Enhanced 10000k 400 MH for veg. $40 bulb and it packs a punch! I was wary at first since it was so cheap but i was definitely impressed with the results
