Anyone use actinic supplementation with 400W MHs?

i was wondering the same thing, i want to go with the 400 watt-XM bulb at 14K but i'm starting to think that the intensity from the bulb will just cover the actinics, so at the moment i think i'll just go with 20K, alot of people have just told me to refrain from actinics if i get a good 14K bulb, but with my past few experiences with 14K's they have'nt been blue enough
