this is why i watch carefully, when they show the slightest sign of drooping, at all, i check the soil, if its dry up to 1.5 inches down, its time for water. and no if you let it dry out too much and droop tooooo much its bad. but it has to dry somewhat, the roots need oxygen as much as the plant needs co2. the plant will droop streasingly if it has too much of one and not enough of the other alot. dont dry out your soil till its compleatly dry... your plant would die first anyway... thats not what i said to do...but its not good letting them droop everytime. stresses the roots. going from completely dry to completely wet every time
