    I can post some in a few weeks. Away for the month... That's actually the primary reason for automating the watering :)Here's one pre-automation. I added another long planter to that.

    Ah, and for anyone thinking of using a diaphragm pump directly into soaker hose, I highly recommend some sort of expansion vessel. Even a 1.5l pop bottle half full of air will do.Running the pump directly into soaker hose, is a recipe for busted pipes/pumps, found that out the hard way :)Also tried a gravity feed, where the water was pumped up, about 2M above the planters, and fed back down, but there wasn't enough pressure to make it efficient.Now I have an expansion vessel, and just blip the pump for 2 seconds, leaving the valve on the planter open for 15. The air in the expansion vessel is compressed by the pump, and then forces the water through the soaker hose for the period the valve is open. Works well, and the pump doesn't seem to mind the short duty cycles.
