The Mystery Planter, then. The upper part of a water bottle a new substrate to test (crushed-clay-pebbles-with-fancy-name) , four or five different seeds, and a wick.

Which, as it turns out, is made of the wrong material: a piece of coco mat whose ability to wick up water is zip. Lesson learned, felt’s next.

But at least the larger seeds I put in don’t seem to mind much, and because my WF is hanging in a brighter and warmer spot now, evaporation – something the coco is capable of supporting apparently – currently supplies enough moisture to keep them going. It remains to be seen whether their roots will reach far enough before they run out of puff.

(started as an update of mine, may deserve a full post)

How about this:
Use regular clay pots for the plants, tie moss/succulents/whateveryoulike to their outside, and do the rest by the book.
The moisture seeping through will feed the ”living pots”, any excess would simply drop below.
Should look nice.

I’m not certain that the clay will let much nutrients seep through.
(But feel free to try. Would probably look nice if it did work.)

No worries there – just look at the calcification on older pots.

Can’t say that I have that many clay pots… A couple of glazed ones(and we know that nothing seeps through on those),

but mostly it’s plastic ’self-watering’ pots… (Only way that I can keep plants alive, it seems… )

If you hung the pots up in net bags, you’d get free trellisses – the handles.

You should be able to drill through clay pots of your careful enough. Quick google search is giving how to results.

One small hole should be enough to allow nutrients through, and the plants could sit in the clay pot with hydroton

Or one could use felt around them, with a thick piece hanging down and acting as a wick to guide the water down to the next pot.

Which would eliminate the need for any tubing which might get clogged, and at the same time ensure the moisture supply.

Here’s something made of felt:
