one night of extra dark period

OK so im supposed to be going somewhere tonight and theres gonna be sombody at my house, so i dont wanna turn my lights on until i get back,,if i let the dark period extend for an extra 3 hours juss tonight will it effect anything?

Most likely no. Just dont make a habbit of it or u will cause hermies and other problems. 3hrs one time shouldnt do any harm.

just one time it should be fine however continuall breaking of its routine and your yeild will suffer your plant will stress and many will turn hermie.

thanks for the replies ...thats good to know
