Self-watering bases lose their hands-off advantage the moment you're stuck manually topping off water — the whole point of automating hydration is not having to check reservoirs constantly. The AC Infinity Auto-Fill Upgrade Valve Kit for Self-Watering Base, 4-Pack fixes that by connecting your self-watering bases to a separate, larger AC Infinity 13 Gallon Water Reservoir for true automatic refilling.
Each of the 4 gravity-fed valves uses an oversized float and secure-seal construction to maintain a steady water level without leaks or electricity, so hydration stays consistent even through a power outage. Standard 3/8" OD tubing and tool-free installation mean the kit drops into most hydroponic setups and water storage tanks without modification.
The expandable design also means you're not limited to a fixed pot count — link additional units as your grow scales, all fed from the same reservoir with no added complexity. This kit allows you to expand or replicate the automation found in the AC Infinity 4-Pot Self-Watering Kit.
Link multiple self-watering bases together for scalable, multi-pot growing setups.
No electricity required, so performance stays steady even through power outages.
Secure-seal construction and an oversized float valve prevent leaks and ensure consistent operation.
Standard 3/8" OD tubing integrates with a wide range of hydroponic tanks and equipment.
