The Areo Pot can only be created with diamond (at least as far I know so far). Diamond says that it increases the decor +100% (doubles it). When you place any plant in it the value displayed in all forms is the same as in a regular planter (value of the plant). Even in the decor overlay it is only the base decor of the plant.
Steps to Reproduce
build areopot with diamond, plant a plant in it, look at decor values in all ways (select aero pot, plant, decor overlay)
