Will reflective surfaces in a grow space enhance plant growth?

Any light that does not reach your garden is wasted.

Reflectors vary widely in the light pattern they create. Usually, areas directly under the light get the greatest intensity. The light is less intense to the sides. Some of the light is sent to areas outside the garden. To increase plant growth, this light should be reflected back so the plants can use it.

Some good reflectors are sheets of Styrofoam, white paint, white plastic mylar and aluminum foil (use the dull side).
