Typical watering cycle for ebb n flow?

i was wondering what a good watering cycle would be if they were in 12/12... how many times should the container flood in daytime and for how long each flood? any advice is extremely appreciated...

ive been searching titles on this forum and i cant find a good answer. thanks all!!!!

It depends what medium you are using and how big the plants are.
Generally speaking when I used RW, I only watered once a day.
Using hydroton I tend to water 4 times a day, just long enough to fill up my tray and only when the lights are on.
