The Self-Watering Fabric Pot Base by AC Infinity is a set of four wick-fed trays that water your fabric pots for you — no pumps, no timers, no daily rounds with the watering can. Fill the reservoir, and high-absorption wick lines draw water up into the pot as the medium dries, keeping roots evenly moist between top-ups. A built-in gauge shows the water level at a glance and the strainer spout makes refills a ten-second job. Available in Standard for pots up to 5 gallons and XL for pots up to 10 gallons.

Wick-Fed Watering Patented design (US #11877546) draws water up through adjustable wick lines as the medium dries — the plant sets the pace, not a timer.
Water Level Gauge A float gauge shows how much is left in the reservoir at a glance — no lifting pots or guessing when to refill.
Quick-Fill Spout Strainer spout on the end of each tray lets you top up with a jug or hose without moving the pot.
Elevated Reservoir Plate Lifts the fabric pot off the tray floor so it isn't sitting in standing water, and keeps algae and other buildup from spreading.
45kg Load Rating Heavy-duty saucer holds a fully saturated pot up to 45kg (100 lb) when used with the reservoir plate.
Catches Runoff Too Doubles as a drip tray — runoff water and nutrients collect in the reservoir and get wicked back up instead of wasted.

Setup Tips — Get the Wicks Working From Day One
  • Pre-soak the wick lines before first use so they start drawing water immediately.
  • Make sure the wicks make firm contact with the base of the fabric pot — that contact point is the whole system.
  • Water from the top for the first week while roots grow down toward the moisture, then let the reservoir take over.
  • Check the gauge every few days at first to learn how fast your plants drink at their size and stage.

How to Use

1
Fit the reservoir plate into the tray and thread the wick lines up through it, adjusting the length so they'll press against the pot base.
2
Sit your filled fabric pot on the plate, centred over the wicks. Nonwoven fabric lets water soak straight through the base.
3
Fill the reservoir through the strainer spout until the gauge reads full.
4
Watch the gauge and top up when it runs low. Larger plants in warm rooms drink faster — the gauge tells you the pace.
5
Rinse the tray and wicks between grows to clear any salt or nutrient residue.

FAQ

Does this work with any brand of fabric pot?

Yes — it's designed for round pots made of nonwoven, permeable fabric, which covers most fabric pots on the market regardless of brand. It won't work with plastic pots or sealed-base containers, since water needs to soak through the pot base from the wicks.

How often do I need to refill the reservoir?

It depends on plant size, temperature and stage — a small veg plant might go the better part of a week on a full reservoir, while a large plant in flower can empty it much faster. The water gauge takes the guesswork out: check it daily for the first week and you'll quickly learn your plants' pace.

Can I put nutrient solution in the reservoir?

Yes. The reservoir stores runoff water and nutrients by design, and you can fill it with mixed nutrient solution. Rinse the tray and wicks between grows to clear salt residue, and give the system an occasional flush with plain water if you're feeding heavily.

Which size do I need?

Standard suits round fabric pots up to 5 gallons (around 20L) with a 3.78L reservoir. XL suits pots up to 10 gallons (around 42L) with an 8.5L reservoir. If your pots sit in between, size up — a bigger tray under a smaller pot works fine, but not the reverse.

Can I use these outdoors?

Yes. They work anywhere you'd normally put a saucer under a pot — grow tents, grow rooms, greenhouses, balconies and outdoor gardens. Outdoors, keep in mind rain will also collect in the tray, so check levels after wet weather.

Will my pot be sitting in water?

No. The reservoir plate elevates the pot above the water line, so only the wick lines touch the reservoir. Water reaches the roots at the rate the medium draws it up, which is what keeps the moisture even instead of soggy.
