I left a light on above my flowering tent last night. It was just a single 20 watt cfl but I'm still a little freaked. There may be a few places light can get in. I'm keeping my fingers crossed.
If they did revert back to veg, how long before they start budding again?
I don't think they will revert back to veg after just one day but some people think they can go hermi if you mess up the light schedule. I've never seen it but you never know.
If they are over 1-2 weeks in flowering it won't revert them to veg.
If your genetics have a hermi tendency and your plants were stressed as is it might trigger the hermi trait.
Just keep an eye for the next 2 weeks for nanners.
