The AC Infinity Self-Watering Fabric Pot Base waters your pots from a built-in reservoir, but you still have to top that reservoir up by hand. The Auto-Fill Upgrade Valve Kit replaces the jug with a float valve fed from a bigger tank: gravity pushes water in as the base drops, the float shuts it off at level, and there is no pump, no timer and no power point involved. You get four valves (one per base), 4.57m of tube, four splitters to chain the bases together and four nozzles. It suits anyone running the AC Infinity bases who wants to go away for a week or stop doing the daily rounds. Two things to know up front: it fits the AC Infinity bases only (Standard and XL), and the reservoir has to sit above the bases, because gravity is the pump.
Specifications
Grower's Tip
- The tank must sit higher than the bases. A milk crate, a low shelf or a stand beside the tent is the usual answer, and the higher it is the more confidently the valves fill.
- Keep the tank lidded and out of the light. A clear tank in a lit room grows algae, and algae ends up in the floats.
- Watch the first fill with the pots off. Let every base fill until its float shuts, then check each joint for drips before you walk away from it.
- Cut tube square with a sharp blade. A ragged or angled cut will not seat properly in a push-fit nozzle and will weep.
- Rinse the valves and flush the line between crops so the floats move freely, especially if you run nutrient solution through the tank.
- For a sense of scale, AC Infinity's own self-watering system pairs four bases with a 49L reservoir.

Frequently Asked Questions
Does it need a pump or electricity?
No. The valves are gravity-fed floats. Water flows from a reservoir sitting above the bases, and the float shuts the valve when the base is full. Nothing is plugged in, so a power outage changes nothing.
Will it fit other brands of self-watering base?
No. It is made for the AC Infinity Self-Watering Fabric Pot Base, in both the Standard and XL sizes. Each base takes one valve and the kit has four.
Does it come with a reservoir?
No. You supply the tank. Any lidded reservoir with an outlet that takes 3/8in OD tube will do, as long as it sits higher than the bases.
Does it work with the XL base?
Yes. AC Infinity lists the kit as compatible with both the Standard (AC-SPA5-4) and XL (AC-SPA9-4) Self-Watering Fabric Pot Base.
How high does the reservoir need to be?
AC Infinity does not publish a minimum. The system is gravity-fed, so the water surface in the tank has to be above the water level in the bases for anything to flow, and more height gives more push. A tank on a milk crate or shelf beside the tent is how most people run it.
Can I run more than four bases from one tank?
Yes. AC Infinity describes the design as expandable to any number of bases. One kit covers four; a second kit and its splitters carry the same line on to four more.
Is the tube the same as Australian 4mm irrigation line?
No. The kit uses imperial 1/4in ID, 3/8in OD tube (roughly 6.4mm inside, 9.5mm outside), which is the standard size in hydroponic reservoirs and fittings. Use the supplied tube and fittings rather than metric micro-irrigation line.
Do the valves need cleaning?
Yes. Rinse the valves and flush the tube between crops so the floats move freely. If you run nutrient solution through the tank, keep the tank lidded and clean, because salts and algae are what gum a float up.
