I am pretty sure someone had already thought of this but here goes.
So what I did is bury a pot in the planters on the top balcony. This way i can slide in a pot of the same size with a plant inside, and have it grow there. I resorted to this attempt because i wanted to make use of the planters (horrible clay soil, when i dug the holes and put water so the soil sediments,it took 6 minutes to drain). Also this makes weeding and moving plants easier.
