Hi.
Installed 5/16" i.d. tubes in the planters as in post #14 instead of those 1/8" narrow green ones. At the beginning got blocked by dirt above their level. After clearing repeatedly, seem to drain fine. No flooding.
Some contraption idea needs to be implemented to ensure the drain tubes will stay unclogged and the phreatic level does not rise, to obtain both the 'draining soil' so often sought-after in gardening and a lasting wet reserve below. In other words, the 'draining soil' to drain into a ~4" depth below. I think
Perhaps reversing wicking ? A wick reaching above the surface inside the drain tubes for draining. Slower, but the tubes would not clog. Hey! Much larger drain tubes diameter with wick inside...
