I'm sorry. I didn't clearly understand the context of your question.

There is a style of "hydroponic system" that originates in Europe (sold under the trade names Leni and Luwassa, among others) that consists of a 3-piece pot - a decorative outer pot that serves as the reservoir, a mesh, net, or slatted inner "culture pot" that contains the LECA and plant, and a gauge, so you don't overfill it. The space between the inner- and outer pots is minimal, so that limits the evaporation.

In my original modification, I just removed the gauge and replaced it with the watering globe.
