With a regular indica I would do 2 or 3 plants with no more than a month veg time, or 1 sativa dominant plant with no more than 6 weeks veg & maybe some LST. Since I only have 3.5' roughly of height to work with I have to plan accordingly: indicas can grow 2x+ the size of when they are put into flower & sativas more like 3x+. You can always try LST to keep them short, or normal (single cola) to keep them confined horizontally but either way I'd say 1-2.5 sq feet footprint per plant. In a box your size, I think SOG would be your best bet.
