Lighting Question

[corper]

In a MH light setup, is it necessary to have VHO or compact lighting worked into the setup (not including actinic lighting, I know why to use that). I was just reading that I should because of the shimmering created by the MH lights. Apparently the flourscent light helps give a more constant light source or some crap like that. Anyone know what I'm talking about or care to comment on the subject? The reason I am asking is I have a 48" T5 fixture and I'm wondering if I should work it into the MH light setup in my hood?
