I found last night that the timer for my lights got stuck on for close to 8 hours past when it should have been in dark period. I immediately turned them off and put it on dark for 12 hours. What do else do I need to do or look out for? Is re veg a high possibility?
If you are well into flower, no worries.
Same goes for a prolonged dark period. They can withstand most one-time incidents, once they get out seedling stage, and
are healthy.
