Rigid pots with openings in the walls that let air reach the root tips. Roots stop at the opening and branch instead of circling, which builds a dense, fibrous root system in a pot that still handles like plastic.

How air pruning works
In a solid pot, a root that reaches the wall turns and circles. In a root pruning pot the root tip meets air at the opening, dries back and the plant responds by sending out new feeder roots along its length. More root tips means faster uptake of water and nutrients, and no root bound plants at transplant.
Sizes
GROW1 Prune-Air pots come in 1, 2, 3, 5 and 10 gallon, packed 12 per box. The openings allow airflow throughout the media and a raised base acts as a built in elevator for drainage. A 6 inch round and an 8 inch square root pruning pot suit early stages, and giant injection molded root pruning pots in 75 and 100 gallon suit trees and long season outdoor plants.
Root Pruning Pots FAQ
Root pruning pots or fabric pots?
Both air prune the roots. Root pruning pots are rigid, so they are easier to move, stack and clean. Fabric pots cost less in large sizes and fold flat.
What media works best?
Soil and soilless mixes such as coco and peat blends. Very fine media can wash out of the openings, so blend it with perlite or coco.
Will they dry out faster?
Yes, slightly, because more of the media is exposed to air. Most growers see that as a benefit since it allows more frequent feeding.
