Do you have seperate rooms for vegetating and flowering VV?

If i were to use T5-8 fixtures in 2 seperate rooms, would it be better to use red spectrum in one room, and blue in the other? - i would have thought if you want to keep your mothers from flowering, you can not give them any red light. also, i thought that baby clones would be better with blue light. aslo, the flowering room would grow better in red light?? i was thinking of using 2 rooms for a faster yeild.

I do apologise if you already answered this question in your last post..
