You can keep a couple bonsai mothers in there with the space you have, but sometimes it's best just to have a place away from soil (=possibility of mold spores etc) for the cuttings.
I got a couple Ott Lights from home dePOT but my buddy who manages the lighting dept says they were discontinued so I have no clue where to get them. lol! Oh well. The point is that they are VERY blue and vegging plants adore them.
You can be even closer with your bulb, but then you would want a pretty small bulb. Cuttings need some, but not much, light. It's not exact. They will find a way to tell you if they are unhappy hahaha!
