I've done the same thing live heading Notify Ground Crew! Planet Claire and The Levitating Ananuki are two other registered nocturnals I grow, but the blooms don't seem to begin opening as early in the evening as NGC making it easier to not mistake tomorrows opening blooms from the ones ending today.
I really like the nocturnal bloomers. The ones I've grown open well, even when the mornings are cold (CMO - Cold Morning Opener), and remain open into the evening.
