Rick,
I've been thinking about how to add some sort of reservoir to the 1020 tray to make the pots self-watering. My current thought is to use a "sham-wow" which really absorbs water, draped over both ends of a 1" thick block of styrofoam sized to fit the tray. The plastic pots and soil would float on top, water would wick up the ends, and as water was absorbed the styrofoam would drop. Still a thought experiment at the moment, but don't see why it wouldn't work.
