If you guys REALLY want DIY smart pots, I have two words for you..."geotextile underlayment" sold at lowes and homedepot as pond underlayment or anywhere else on the internet. I get 5ft by 100 ft for around 65$. With a good sewing skill, and a bit of reverse engineering on an original smart pot, youre in the money !
