It depends on the size of the seedling but around 3 to four days.If it drys out too much the pland will start to wilt. Feel the dirt. If it feels real wet dont water but if just where a pinch wont stick together easy then its time to water. If its a small plant in a big pot it will go several days. Hope that helps Slim
thanks... there in a small pot like the ones u get when u buy a small plant from walmart like a tomata plant.I just started them today so i gave them a good soaking to wake them up
