Howdy, Frank! Nice to hear you are getting settled in to your new place.
I remember some of his pics, woofie. His pots were right next to each other (for the most part), touching. I imagine a small amount of water would dribble onto his deck but mostly it would seep down the inside rim into the soil.
You could do the same set-up, a bit more expensive but a one-time expense, using a feeder hose and either drip emitters or mini-hose that taps into the main feeder hose. (I should probably go back up and re-read this thread; perhaps that has already been mentioned.)
