I'd use 1 inch foil coated foam core insulation from someplace like Home DePot..
You can cut it to fit, and it will reflect almost as well as white walls.
Be careful not to restrict air flow to your plants. It's more important than a little more reflected light.
Eventually you won't need anything. Those 5 plants should fill a 4x6 space nicely, with a bit of room for good light penetration.
Keep the lights as close as possible (like less than 6 inches) to the top of the plants.
