I'm not sure I understand what you mean by "using plastic grill (for weight support) under foam for growbed media?" Are you referring to same aeroponic system your planing for potatoes, or another type of system and or plants? Anything that comes in contact with the water/nutrients should be some type of plastic. If it doesn't come in contact with the water/nutrients, then you can use just about any material to support the system with.
Imagine something like that:

With better spacing and hole dimensions, to fit the spacing required for the foliage growth as well as to accommodate the growbed. The whole thing would be light isolated with foam and foil (non-toxic) and the tubers would grow in the air in a plastic container.

Do you have any predictions for root maximum length? I guess it won't be a good idea to let the roots reach the bottom of the container as there would always be a pool of water and they would rot?
