A friend of mine has an Ebb and Flow system and is going to be starting 10 plants, 5 each in an X formation in about a 1.5'x3' rubbermade thing. The tubs take less than 2 minutes to fill with nothing in them. How often should he run the pump? I know there are a lot of options and you should just pay attention to the plants, but I remember reading something like 15 minutes every 2 hours, an hour before lights on, and nothing during the dark. Is that a good schedule to start with?
