i have a question, while my lights are off i sometimes have to go into the room, there are no other lights that are shining into the room and outside of the room (hallway) is pretty dark, but not pitch black, a little light seeps through the bottom of the doors of the other room and lights up the grow room just slightly, i try to close the door ASAP and only use my cell phone for light and do not point it at the plants. Is this okay? or should i not go in there AT ALL? Also what kind of light can i use to go in there? I heard a green light? but what kind of green light?
