My plants got an extra 12 hours of darkness, will they recover?

Hi
I had a disaster today. I currently have 6 white widow female plants in veg mode (18/6, soil). The plants are 4 weeks old. I had a power cut to-day and my plants received an extra 12 hours of darkness. I re-adjusted the timers and put them back onto their normal cycle of 18/6.
Do you think the plants have suffered in any way, will they recover? Iâ??m switching them to 12/12 this weekend, under a 400hps.

Thanks in advance

They will be fine. You could probably get away with doing the switch as planned but consider giving them a full week to ten days back at 18/6 before you switch to 12/12 just to be sure they are back on cycle.

Darkness is entirely fine for plants. They just think it's a cloudy day or something obscured their view of the sun. Now if you had 12 extra hours of light when the plant was thinking it was night time, hard for the plant to explain that in its natural environment.

No harm done, just put them back on their regular schedule and treat this one as a cloudy day.

Darkness in a tent/room is much different than a cloudy day for sure. The sun still has certain rays that penetrate through cloud cover. Also if something obstructs the view of the sun to the plant there is still reflected light from all around. Being in a dark tent/room for a day is much worse than being outside on a cloudy day...


Your plants will be fine. Added darkness changes the hormone levels in the plants... Takes time to do so. As long as you dont keep messing with the light schedules you will be good.

Some people actually give their plants extra dark hours when they switch to 12/12 to promote hormone buildup to start the flowering process early. Why not just change to 12/12 now?
