{"product_id":"smartgro-fabric-pots-air-pruning-grow-pots","title":"Smartgro Fabric Pots | Air Pruning Hydroponic Grow Containers (11.6L to 41L)","description":"\u003cp\u003eRoots in a standard plastic pot hit the wall and circle. They keep growing in the same direction because there's nowhere else to go, wrapping around the inside of the container until they're competing with themselves for space, oxygen, and nutrients. Air pruning stops this. When a root tip reaches the breathable fabric wall of a Smartgro pot, the exposure to air naturally desiccates the tip, triggering the plant to branch laterally and produce a dense, fibrous root mass instead of a single circling root system.\u003c\/p\u003e\u003cp\u003eThe result is more root surface area, better nutrient and water uptake, and stronger plant performance from the same container volume. Smartgro Fabric Pots are available in 11.6L, 15.1L, 19.3L, and 41L sizes, with a square profile designed to fit Wilma and Origin hydroponic drip systems, flood and drain trays, and standard grow tent setups. Four built-in side stake slots allow plant support structures to be added without disturbing the root zone. Washable and reusable across multiple grow cycles, they're a cost-effective upgrade from single-use plastic pots.\u003c\/p\u003e\u003ch2\u003eHow Air Pruning Works\u003c\/h2\u003e\u003cp\u003eAs roots grow outward through the growing medium and reach the fabric wall, the breathable material allows air to contact the root tip directly. This air exposure causes the tip to dry out and stop growing, a process called air pruning. The plant responds by producing multiple new lateral roots from behind the pruned tip, branching outward and filling the container with a dense, fibrous root network. This increased root mass improves the plant's ability to absorb water and nutrients efficiently, supporting faster growth and higher yields compared to root-bound plants in solid containers.\u003c\/p\u003e\u003ch2\u003eKey Benefits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir pruning fabric technology for stronger root systems.\u003c\/strong\u003e Breathable walls naturally prune root tips on contact, triggering lateral branching and producing a dense fibrous root mass that maximises nutrient uptake.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable in four sizes from 11.6L to 41L.\u003c\/strong\u003e Covers seedling through to large fruiting plant requirements, with a size suited to every stage of the grow cycle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare profile fits hydroponic tray systems.\u003c\/strong\u003e Designed to sit flush in Wilma and Origin drip systems, flood and drain trays, and standard grow tent floor layouts without wasted space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour built-in side stake slots.\u003c\/strong\u003e Allows plant support stakes and trellis structures to be added directly to the pot without disturbing the root zone or growing medium.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature regulating fabric construction.\u003c\/strong\u003e Breathable material naturally insulates the root zone, reducing overheating in warm grow environments and improving growing medium stability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReusable and washable across multiple cycles.\u003c\/strong\u003e Clean between grows and reuse, reducing long-term container costs compared to single-use plastic pots.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible with coco coir, soil, and hydroponic media.\u003c\/strong\u003e Works with all common growing media used in indoor cultivation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eAvailable Sizes\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e11.6L.\u003c\/strong\u003e Suited to smaller plants, herbs, leafy greens, and early-stage vegetative growth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e15.1L.\u003c\/strong\u003e Mid-size option for vegetative plants and medium-yield fruiting crops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e19.3L.\u003c\/strong\u003e Popular size for high-yield fruiting plants in recirculating drip and flood and drain systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e41L.\u003c\/strong\u003e Large format for maximum root volume, suited to long-cycle crops and commercial production.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial.\u003c\/strong\u003e Breathable horticultural fabric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape.\u003c\/strong\u003e Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes.\u003c\/strong\u003e 11.6L \/ 15.1L \/ 19.3L \/ 41L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStake Slots.\u003c\/strong\u003e 4 x side slots for plant support\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReusability.\u003c\/strong\u003e Yes, washable and reusable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication.\u003c\/strong\u003e Hydroponics, soil, coco coir systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility.\u003c\/strong\u003e Wilma systems, Origin systems, flood trays\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximate Weight.\u003c\/strong\u003e 11.6L approx. 0.1 to 0.2 kg, 15.1L approx. 0.15 to 0.25 kg, 19.3L approx. 0.2 to 0.3 kg, 41L approx. 0.4 to 0.6 kg\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently Bought Together\u003c\/h2\u003e\u003cp\u003eSmartgro Fabric Pots are designed to drop directly into the \u003ca href=\"\/products\/origin-hydroponic-system-recirculating-drip-australia\"\u003eOrigin Hydroponic Recirculating Drip System\u003c\/a\u003e, which provides timed nutrient delivery to each pot via top-feed drippers.
