I grow them close to multiple cool-white fluorescent lights, 20 hour photoperiod, and always in trays of water --- 24/7/365. They go in and out of their different leaf phases, seemingly on their own schedule, but usually almost in sync with each other and most of the other tropical pings.
Since they originate nearer to the equator than where I am, I can't see how their seasonal light/photoperiod would change as much as most of ours does here, above or beneath the equator, either in the Northern or Southern hemispheres.
