The Smart Pot® is a fabric aeration container made of a porous, breathable fabric which is made specifically for growing trees and plants. The Smart Pot® drains excess water and making it difficult to overwater allowing the home gardener to use a wider variety of mixes. It releases heat, university studies have shown that the Smart Pot can be up to 20 degrees cooler than a traditional hard sided container leading to better growth in hotter months. Roots growing in a Smart Pot® come in contact with air which automatically prunes them leading to a better root structure and a better yield.
