One of the issues you may find, over time, is the buildup of minerals on the outside of the pot.

In such a setup, essentially all of the evaporation is on the outer surface of the pot, swampstick, etc. As that happens, any dissolved minerals, whether they be fertilizer or stuff already in the water, will precipitate onto the surface.

The only ways to truly control that is to use pure water inside the pot, and feed via a spray from the outside, then flushing the surface well.

If you just flush it regularly washing the roots and the vase off it doesn't seem that buildup would be any more of an issue than with regular hydroponic setups.

Neat idea, I've never seen anything quite like this. And successful too! Thanks for sharing.
