4" minimum or you could risk burning your girls. It would also depend on how cold the air is going over your light, and weather you could keep it cold enough so the glass didn't get hot, I use a cool tube rather than a hood, mainly due to size.

If you can feel a temp difference holding your hand over it.. Back it off or you'll cook your girls. Hang a hydrometer at canopy height.. Problem solved
