Power out HELP plz

I'd say you are lucky that the power went out now instead of a more critical phase of growth. I'd let the plants go until you think they are ready for harvest. Since you have them inside I assume freezing isn't a problem so while it may be cool the plants should be OK.

What is the room temperature and how long left untill the planned harvest day ? one of my friends accidentaly left unset timer and plants were in dark for 3 days and nights during late flowering stage :) nothing hapened but they could possibly tur into hermies pollinate themselves due to the stress...
