The platform is simply sized to the pot(s). I might have a dozen or more, 4" pots on a single platform or a single, huge 28" diameter pot (like my 25+ year old fiddle leaf ficus is in) on a 24" x 24" platform. The platform can be as small or as large as you wish. Someone handy with a skill saw can even make the platform round to fit the base of a particular pot. Why don't you think this concept would not work with large pots?
