Hi all little confused on this new system I've just got. I've done a test run couple of leaks here and there. So the tank is supposed to be 42 litres but its about 35. So when I run it the top tray starts to fill but before it reaches the overflow water runs out in the tank so my Question is
Is the overflow for later on when the plants roots take up the room in the top tray or should it be like a continuous cycle because in the early stages the full res is going to empty into the top tray so that means the young plants will sit in water for a long period. Or will it return back through the supply pipe? Please advise.
