Description
Smart Pot in a 45-gallon / 170-litre format for production-scale growing, large outdoor plants, trees and any application where substrate volume needs to be substantial enough to support the plant through a full season without root-bound symptoms limiting canopy development or yield.
Breathable fabric walls air-prune roots throughout the cycle, ensuring the dense, lateral root architecture that accesses the full 170-litre volume rather than developing as a restricted mat at the pot perimeter. Drainage and passive root zone cooling through fabric evaporation. Washable and reusable.
170 litres sits in the range most commonly chosen for large outdoor tomatoes, chillies grown as short-lived perennials, and mid-to-large trees and shrubs in their first several years before ground planting or stepping up further. Compared with the 65-gallon format above it in the range, 170 litres is still practical to move by hand when empty or lightly filled, making it a realistic size for growers who need to reposition containers seasonally rather than leave them permanently sited. As with all Smart Pot sizes, the fabric wall works because air, not a physical barrier, stops root growth at the container edge — roots that reach the wall are exposed to air and stop elongating rather than circling the pot as they would in a solid-sided container, which is what produces the dense, branching root system that makes the most of the available substrate volume. Water and feed slightly more frequently than you would a solid pot of the same volume, since evaporation happens across the whole fabric surface rather than only at the top. Reusable across multiple seasons if rinsed out and left to dry fully between crops — check for any root residue caught in the fabric weave before reuse, as decomposing root matter can harbour pathogens into the next cycle.
Pair with a saucer or drip tray sized to the base diameter if growing on a surface sensitive to run-off staining, and check the fabric periodically for wear at the base seam if the pot spends extended periods outdoors in direct weather.
