Who This Is For

You are adding automated irrigation to your tent because your current manual schedule requires you to stay home every day to prevent dry-out periods.
You are linking your reservoirs together because your current setup limits how many plants you can water from a single central supply.

What We Found

The float valve is far more responsive than the generic plastic bits you find in most retail garden supply kits.
We recommend keeping a few feet of slack in your tubing lines to allow for easier tray cleaning between harvest cycles.

What Users Say

Users who linked their reservoirs say they finally feel comfortable leaving the garden unattended for weekend trips.
Gardeners who converted to this auto-fill system report they no longer see pH swings caused by letting reservoirs run bone-dry.

AC Infinity Auto-Fill Upgrade Valve Kit for Self-Watering Base, 4-Pack

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 bases to a separate, larger 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 self-watering bases as your grow scales, all fed from the same reservoir with no added complexity.
