I have been using 10Qt and 5Qt pots. On my second set of girls... but mine have never filled out like those in ur pic. Mine are NL /BB auto. But I LST. My other 2 I think I will let nature form them till harvest. LST on auto can go good or bad, depends. Ur girls look great! All I have is Indica ... I would like to try some Sativa seed if ever get around to finding them.
