What Major said....adding that Smart Pots are one of 1st/older fabric pot brands. No hem on top so can be kind of floppy. I like Geopots outdoors...have hem & thicker so better if you have to tote/move them around outside. But best reason to use fabric pots if for air pruning of roots thus more root laterals instead of root swirling in hard pots. End result is better root system. The Root Pouches I mentioned earlier are a super value & have been perfect for me indoors.
