AutoPot XXL Self Watering Systems, 1-100 Pots

Grow in 9 or 13 gallon pots with zero daily watering The AutoPot XXL is a gravity-fed, self-watering system built for large fabric pots. Each module uses an AQUAvalve5 to deliver water and nutrients only when the plant draws them down, so root zones cycle naturally between wet and dry without timers, pumps, or electricity. Systems scale from 1 to 100 pots off a single reservoir, and every tray accepts either 9-gallon or 13-gallon GeoPot G Lite fabric pots. Zero electricity BPA-free pots  Plant driven watering Free shipping on orders over $49 30-day returns on all orders Serving growers since 2006 Gallery Top 10 tips for running AutoPot systems Side by side Hand watering big pots vs. AutoPot XXL Hand watering large pots Large pots dry out fast and need heavy, frequent hand watering Overwatering or underwatering is constant guesswork Runoff collects in saucers, creating mess and salt buildup Leaving town for a weekend means finding a plant-sitter Scaling past 4 or 5 pots turns watering into a full-time job Requires pumps, timers, or drip emitters that need regular maintenance AutoPot XXL AQUAvalve5 delivers water on demand, only your job is to refill the tank Plant-controlled wet/dry cycle prevents both overwatering and drought Zero runoff, zero waste. Every drop goes to the plant Fill a 25-gallon FlexiTank and leave for days without worry Link 1 to 100 pots from one reservoir. Add modules any time No moving parts. The only maintenance is rinsing the filter when you refill Key features What the XXL system actually does AQUAvalve5 plant-controlled watering 50% less water The valve opens when the tray is dry and closes when it fills to about 1 inch of depth. Each pot gets its own valve, so individual plants draw at their own pace without recirculation or waste. 9-gallon and 13-gallon fabric pots Each XXL tray accepts either a 9-gal or 13-gal GeoPot G Lite fabric pot. Both pot sizes share the same diameter, so they fit the same tray with no adapter needed. Air-pruning fabric pots for stronger roots Porous sidewalls stop root circling. Instead of spiraling around the pot edge, roots branch outward and create a denser feeding network than you would get in a solid plastic container of the same size. Zero electricity, zero pumps The entire system runs on gravity. Raise the reservoir at least 6 inches above the highest AQUAvalve5, and water pressure does the rest. No power cords, no moving parts to maintain or replace. Scales from 1 pot to 100 pots Start with a 1-pot system and add XXL expansion modules whenever you need more capacity. Every module connects to your existing reservoir line with 3/8-inch or 1/2-inch pipe and cross connectors. Works with mineral or organic nutrients The AQUAvalve5 has a 66% larger inlet than the previous generation, reducing clogs with thicker nutrient solutions. For organics, AutoPot recommends running a small pump in the reservoir for 15 minutes every 2 hours to keep the solution mixed. Specs Technical details Pot sizes 9 gal or 13 gal GeoPot G Lite fabric Valve AQUAvalve5 (5mm inlet, 66% larger than v4) System sizes 1, 2, 4, 6, 8, 9, 12, 16, 24, 36, 48, 60, 80, 100 pots Pipe sizes 3/8" (small systems) and 1/2" (6+ pots) Power required None. Gravity-fed, no electricity Reservoir options 12.4 gal, 13 gal, 25 gal FlexiTank, or No Tank Pot material BPA-free, lead-free fabric (GeoPot G Lite) Compatible media Soil, coco, perlite, clay pebbles, or blends How the system works 1 Connect the reservoir Place your FlexiTank or hard tank at least 6 inches above the highest tray. Attach the inline filter to the tank outlet, then run 3/8-inch or 1/2-inch pipe to your tray line. 2 Set up the trays and pots Place each XXL tray on a level surface. Drop in the PotSock, then set the 9-gal or 13-gal fabric pot on top. The PotSock keeps roots from reaching the AQUAvalve5. 3 Plant and hand-water for 7 to 10 days Pot up your plants and water them by hand from the top for the first week to 10 days. This lets roots establish before the bottom-fed system takes over. 4 Turn on the system and walk away Open the inline taps and fill the reservoir with water and nutrients. From here, the AQUAvalve5 handles everything. Refill the tank when it gets to about one-third full.

Most growers in a 4x4 tent run 4 pots in 13-gallon. If you already have a reservoir, choose "No Tank" and save. Call or email us: 716-217-0353 / help@happyhydro.com Questions Frequently asked questions Is the XXL hard to set up if I've never used AutoPot before? No. The whole system is push-fit pipe and gravity. You place the tray, drop the pot and PotSock in, run one pipe from the reservoir to the tray, and open the tap. The AQUAvalve5 snaps into the tray with no tools. AutoPot includes full printed instructions with every kit. Can I use living soil or organic nutrients with this system? Yes. The AQUAvalve5's larger inlet handles thicker organic solutions better than older AutoPot valves. Many growers run water-only living soil in the XXL fabric pots and only add plain water to the reservoir. If you are running liquid organics through the line, keep the reservoir stirred and clean the filter when you refill. Mineral salt-based nutrients work with no extra steps. Should I pick the 9-gallon or 13-gallon pots? The 13-gallon is the default for most indoor growers who want big root zones and longer periods between tank refills. The 9-gallon fits in tighter spaces and still provides more root volume than a standard 5-gallon pot. Both sizes share the same diameter and fit the XXL tray directly, so you can mix and match within a single system. How often do I need to refill the reservoir? That depends on pot count, plant size, and environment. Large plants in full production drink significantly more than seedlings or young veg plants. AutoPot recommends never letting the reservoir run completely empty. Refill when it gets to about one-third full to maintain consistent gravity pressure to the valves. Can I add more pots to my system later? Yes. AutoPot sells individual XXL expansion modules that include a tray, valve, pot, PotSock, and a cross connector. You splice the new module into your existing pipe run, and it starts working immediately. You can expand from 1 pot to 100 pots with no changes to the reservoir setup other than upsizing the tank if needed. Do I need a reservoir, or can I use one I already own? You can select "No Tank" when ordering and use your own reservoir. The only requirement is that the tank outlet sits at least 6 inches above the highest AQUAvalve5, and that you use an AutoPot inline filter to prevent debris from reaching the valve. AutoPot's FlexiTanks and hard tanks are purpose-built for this, but any food-safe reservoir with a bulkhead fitting will work. What if my order arrives damaged or defective?
