at that size watering once a day might be enough , try this "water once when the light comes on, then keep eye on them thru the day,if they dont wilt before the light goes out,keep this schedule. if they do wilt before the light goes out water at lights on and again 6 hours later. total of twice a day.as they grow you may need to increase this a lil but even at that 3 times might be your max.the important thing is no more than whats necissary ^^
