Air size in Smart Pots
As roots grow in containers, they eventually reach the sides. With rigid-walled pots, as the roots reach the sides of the pot, they begin to circle and continue to circulate in search of a more favorable environment. These root systems have very few branches, are often tangled up in themselves and, depending on the type of plant, have produced a taproot. These characteristics can hamper the plant's rate of growth and, in some cases, its chances of survival when transplanted.
Smart Pots are manufactured in a single, non-woven, polypropylene pot. Roots grow sideways, developing rootlets. They don't run in circles in search of oxygen. The fabric lets air pass through. The root mass occupies all available space in the pot, producing rootlets instead of circling in search of pockets of oxygen.
Smart pots enable plants to absorb water and nutrients from the soil or substrate.
