    This is one of the best hydroponic garden I saw, full of smart and simple features that make this system great to maintain and control. I'm trying to build my first one, of course much smaller than yours to start, I'm a web developer and I love your control box! Of course I will take all your tips and ideas to buld mine. Thanks a lot for sharing.

    The little grommet that you are using for the outgoing water against the 4" pipe, what is that? How did you make that connection without leaks?
