Developed in 1984, the Smart Pot is a fabric aeration container that causes root enhancement, or root pruning. When a root tip reaches the side, it does not circle, instead it locks into the fabric. This immediately causes a branching, or pruning, of the root creating a healthy, fibrous root branch. BPA free and lead free, the Smart Pots are hand crafted in the USA and are the original fabric aeration container. Increase your plants yield today by purchasing Smart Pots!
