For predators, I'm finding Orius and Aphidius to be a great combination indoors, if you don't have any hot lights around to kill them.
Aphidius parasitize the larger, more mature aphids.. Orius hunt the flowers and crotches, targeting smaller aphids, thrips, and whatever bothers them. I've also got a mix of other stuff, but those two seem to make the best team I've found for long term control.
Neither have required more than a little misting of designated areas 2x daily.. And having something in flower. Unlike Ladybugs, neither needs any assistance to find infestations.
