Smart pots as in felt pots? Well.. True.. You shouldnt move them so much. but how often do you have to lift your plant high off the ground? Just testing the weight of the pot for watering purposes shouldnt cause the rootball to break if the pot is well made, and full of soil. Not with a 3gal at least.
Anyway... the felt pots also filter any runoff water that drains out of the pot, so you won't have bits of dirt everywhere on the floor of your tents and such. Makes cleaning easier, and less frequent. Also, a benefit that I just discovered of the felt pots, is that if they are on the floor of your tent, they suck up the water that drained out of them which is good because it cleans that up, and it also, lets them take back some from the bottom of the pot if it is too dry...
Just some thoughts.
