I got a room in a flower and across the room by the window there a little little bit of light peaking through. Like a little glow. The room and plant are still in darkness. Just wondering if light needs to touch the plant to take effect or will the plants seek that little little bit of light ?
Its hard to picture exactly what you are describing. To me it sounds like you have a tent or closet in a room and maybe the widow in that room is blacked out. If that widow has a tiny light leak it may not effect the plants but its hard to say without seeing it. They dont have to be in 100% underground cave like darkness, but direct light is a no no. Maybe a pic of the problem would give us a better idea of the situation.
Just make sure the tent is light proof the room it’s in doesn’t matter
Ask yourself, is the light in here any more intense than that of a full moon. If yes, I’d be careful. If not, wouldn’t sweat it. But the plants definitely don’t need a level of pitch black that causes you trip your way through the grow room .
Fix it and forget it, know what I mean? Blackout curtains work.
