ROOT NURSE 17.5 LITRE SQUARE

Description

Root Nurse 17.5 Litre Square is a fabric air-pruning pot that uses breathable, textile fabric walls to stimulate the formation of a dense, fibrous root structure through the natural air pruning mechanism — delivering the root development benefits of air pruning in a generous 17.5-litre square format ideal for full-cycle growing of medium to large plants. We have been recommending fabric air-pruning pots to UK growers since 2017 as one of the most meaningful container upgrades a grower can make — the root architecture produced in a fabric pot consistently outperforms that of a rigid plastic container of equivalent volume.

Why Fabric Air Pruning Pots Create Better Root Systems

In a rigid plastic pot, roots that reach the container wall begin to circle the interior, growing parallel to the wall and forming a dense, matted, inefficient root structure. The circling roots have a lower ratio of active root tips to total root mass than a naturally branching root system, reducing the plant’s capacity for nutrient and water uptake. Root Nurse fabric pots solve this problem through air pruning — the breathable fabric walls allow air to reach root tips as they approach the pot surface, desiccating and pruning them naturally. This pruning stimulates lateral branching behind the pruned tip, generating multiple new active root tips from each pruned end. Over a full grow cycle, the result is a densely branched, fibrous root system with far more active root surface area than a plastic pot equivalent — translating directly into more vigorous growth, better nutrient uptake, and higher yields. The 17.5-litre square format maximises root volume in a space-efficient footprint, fitting neatly into standard grow trays and tent layouts.

How to Use Root Nurse 17.5 Litre Square Pots

Fill with your preferred growing medium — coco coir, soil, or perlite blend. Transplant your plant into the filled pot. Water normally, ensuring adequate drainage. The fabric walls allow oxygen to reach the root zone from all sides, which also benefits root zone health beyond the air pruning effect alone. Root Nurse pots can be reused — rinse thoroughly and allow to dry fully between grows. Inspect the fabric for tears or degradation that could compromise structural integrity before each new use.

Root Nurse fabric pots work excellently with AutoPot systems, quality coco or soil substrates, and any nutrient programme. Browse our full range of growing containers, fabric pots, and drainage trays for the complete growing infrastructure setup.
