This is my first year using the smart pots and I'm still on the fence. I think they do require more water than other containers and if you're just looking for a pot to grow something in, the plastic nursery pots are a lot cheaper. However, the earth-friendly smart pot won't add to the landfill problems. I really can't tell any difference in the way plants grow or produce in the smart pots. Unless you get the really large ones, there are no handles to move them around. One of the 'pros' is that if they're emptied in the fall, they'll fold or roll up for storage. Yes, drainage is good, but the plastic nursery pots I have drain well too. The Ace Hardware in my area carries the plastic pots and are very reasonable ... less than $1 for the smaller sizes (1 and 2 gallon), then slightly more for the larger sizes (up to 7 gallon). I've seen them (the Smart Pots) in some hydroponics stores, so you might check in your area if you want to see them before you buy. Worm's Way also carries them, but I realize Bloomington is quite a haul from Hobart for you.
I'll be interested in other people's take on these as well. Maybe I'm missing something, but right now I have no plans to purchase any more of them.
