It wasn't until a few years ago I was made aware of a certain type of growing container that air prunes the roots of the plant. I think it was called air pots, simple and effective concept and execution. I believe @Vance Wood has a patented pot design utilizing the same principles with the sides of the pot exposed and contained with a mesh. A few months ago I found there are vendors out there who are printing 3D printed pots utilizing the same concept but not made to look like a training pot. Definitely something more refined, I really like how it looks my concern is, these are made of plastic and so are colanders and they deteriorate with time. Is this something viable long term? What are your thoughts?
