630w

Is it possible to use 3100k & 4100k bulb simultaneously in a 630w (315w x 2) unit? I understand 4100k is for veg and 3100k for flower. I figure broader spectrum with both bulbs in use. Anyone doing this or are most of you cmh users running 2 3100k in yours? Thank you for your inputs! Apologies...
