The AC Infinity Heavy Duty Fabric Pot, 3 gallon is a reusable grow bag that air-prunes roots for a denser, healthier root system. This 5-pack is made from thick 500G nonwoven fabric with reinforced double stitching and nylon handles, holds a true 12.9 L (3.4 gal) when filled to the stitch line, and has steel rings around the rim for twist-tie plant training. Quick Bloom Lights is the official Australian importer: stocked in Sydney, shipped domestically.
Air-pruning for stronger roots
In a hard plastic pot, roots reach the wall and circle, and the plant ends up root-bound. In fabric, root tips that reach the wall meet air and stop growing, so the plant branches out with new feeder roots instead. That gives a dense, fibrous root mass that fills the whole pot and takes up water and nutrients evenly. The fabric also drains and breathes on every side, which makes it very hard to overwater and keeps the root zone from overheating.
Built heavy duty, made to reuse
The 500G fabric is thicker than typical grow bags, so a full, wet 3 gallon pot keeps its shape and can be carried by its nylon handles without tearing. Reinforced double stitching holds up season after season, and the pots are machine washable, then fold flat for storage. The fabric is BPA-free. Steel rings around the rim let you run twist ties straight through for low-stress training, no modifications needed.
Pair it with a self-watering base
Sit the pot on the standard self-watering base and it feeds water up into the root zone through wick lines, keeping the medium evenly moist between top-ups. Add the Auto-Fill Upgrade Valve Kit and every base refills from one reservoir by gravity. Fill it with AC Infinity coco coir: one brick makes 11.36 L of ready-to-use medium.

FAQ
Is the 3 gallon the right size for me?
Match the pot to your space and how long the plant will stay in it. At 25.4 cm across, it sets how many pots fit on your tent floor, so measure first. The range also comes in 5 gallon, 7 gallon, 10 gallon; see the full size table in our fabric pots collection.
What does "true capacity" mean?
Fill to the double stitch line and you get the full volume on the label: 12.9 L. Many fabric pots are sized to the brim and hold less in practice.
How do I water a fabric pot?
Water slowly until a little runs out the bottom, then let it dry back before watering again. Fabric drains and breathes much faster than plastic, so expect to water more often, or pair it with a self-watering base to even that out.
Can I reuse them?
Yes. Knock out the old root ball, wash the pots (they are machine washable), let them dry fully and they are ready for the next cycle.
Do I need a saucer underneath?
Yes. Fabric drains through the base and sides, so stand it in a saucer or tray. The standard self-watering base catches runoff and feeds it back to the plant.
