I just built a new grow room and my fresh air intake is in the floor. When the lights are off you can tell a faint "wisp" of light entering the room. Is this critical? How do outdoor plants flower when out under the stars and moonlight? Those plants are obviously not in total darkness so can I let a little of that same light into my grow room? It's not enough to read by etc but it's not pitch cave black either...
