How much is a good deep soak, and then how often? I'm going to keep it simple: splitter to timer to hose to soaker. I don't have any experience with soakers, though. How long would it take with a soaker to get a good deep water?

Also, here's what I have: rhubarb (existing), tomatoes, jalapeños, and one basil. Should I just set the soaker up with all of it? I don't know what rhubarb is supposed to take, but I've never done anything with it before. Will watering it that way be too much for it?
