I might do something like that. The roots are going to have a lot of room to grow and it will probably stretch a bit. Appreciate the idea. Thanks!A three ring tomato trellis upside down rests perfectly on a 5 gallon bucket. A few large clamp paper clips should hold it solid enough to the lip and you bend the legs to what whatever shape you want your canopy. You could also attach a couple of nets to the rings/legs for single pot scrogging which gives you the ability to move plants.
