A light leak is when a grow room is giving outward signs that its there when the lights on aka around a door. Foam weatherstripping is pretty cheap way to fix light leaks.
During the flowering stage it is not good to let any light into where the plant is during the off period of the light. Letting "light leak" into where the plant is causes stress and may turn your girl into a hermaphrodite. The plant must remain completely in the dark during the flowering stage.
