Check this out: http://i52.tinypic.com/25s4ot3.jpg All they are are reusable shopping bags from the dollar store. A 5 gallon smart pot is $6, a 5 gallon bucket is about three - these are only $1!!! They are made really good - don't seem like they are going to rip, handles stay on even after filled with wet dirt, and they have a little insert that helps them hold their shape. I just can't get over how damn good they are - only downside is that I think they only come in the 5 gallon size. You could try to fill them less full, but they'd be short and fat, not tall and skinny. Thinking maybe a bag, part way up the base would keep them from dripping everywhere?
