I cannot do that as it would stick too far out from the house and the rain would hit the pings in the winter.
I discovered today that the problem is mainly with the very last ping hole. As in there are 5 that are almost the same wetness and there is one which is much wetter. I will just have to water according to the needs of the five and hope the 6th one lives OK. Either that or make the media well draining there.
P. gigantae can handle a wet growing environment, right?
So not much of a problem, I guess. Auto watering is working very well. I just have to keep adding more water to the reservior because it is so small!
