Well, my Pipe Siphon has been operating non-stop now for over 6 months. No cleaning, tweaking or adjustments, I even change to a small pump, added vertical towers and change my plumbing when I added my Whirlpool Filter. I planted my radishes right on top of where I buried the Pipe Siphon...because they have a short root system.

On my potato plant it sprouted up 2 days ago, looks like it should do will in the GB. It would be nice just to reach down into the media a pick your potatoes with out killing the plant.
