Based on the experiment above, I would say if your pot has any bottom holes that allow the pond water (which is supposedly full of nutrients) into your pot, you would have no need to water or do much other maintenance. You can see these ears and Hibiscus acestosella are very happy. They easily reached 3' tall in here within a short time and never blinked. They shot sprouts out beneath and on top of the stryro giving me lots of free plants.
