I have one Smart Pot that I just stumbled across this year !
Testing it out, but pretty awesome....

Plan to buy more root pots (brown ones) at megagarden.

For those that see winter, what do you guys do with your pots during the cold winter months.

If/when I plan to use more of these pots, I don't forsee myself scooping/dumping out all the soil onto the garden beds and repotting them every season. Besides, it will make a huge mound and I won't have a place to throw the snow
