I have attached the herbs traffic light in front of a window on the ceiling. The supplied iron chain keeps loose the weight of the damp earth. Unfortunately I could not quite evenly distribute the weight so that the pyramid depends a little crooked. For me it fulfills the full purpose, however, the bottom shell is not quite done, so you should take out the top hole, through which passes the chain itself (through a cut plastic pot or the like), so that no soil can fall through once one turns to the pyramid. Unmistakable is the material from which the traffic lights - plastic. Planted but it looks less sober and delights me every time I see them. ;)
