Automatic strains can stand any light schedule you want some most of the growing give 18/6 but any light schedule is proved to be the best yet.
About change for a bigger pot i will advise you do as soon as possible cause i see your roots coming out from your pots already. If you don't want to stress you plant do it fast.
Passing to a green house if fine but your lower temperature can not be less than 12'celsius be awere of than.
Hoppe it helps on your duties.
Happy growings
