They fill themselves. There is a reservior of fertilizer you dont see in the picture that the tube is inserted into.
When the dial spins the syringe sucks and blows....at 2am it sucks and at 12pm it blows. Welll sorta just to give you an idea...im sure it sucks all night and then blows all day. But you get the idea...right?
Sorry if it not my place to answer this question.
