Someone left the light near the pc box on for a couple hours in to the 12 12 cycle. 2 weeks in to flowering, will it hermie?
If that's the only light-related incident you should be fine. Your growbox should be light-tight so that leaving a light on near the box isn't a problem in the first place...
Make your box light tight. Use duct tape its cheap. 2 dollars per roll at Walmart. Or through a sheet over it while the lights off.
