AutoPot Tray2Grow Slim Watering System

AutoPot Tray2Grow Slim — Happy Hydro Automate your watering for under $100, no power required The "Slim" in the name refers to the accessory package, not the tray. This is the exact same full-size Tray2Grow (43.9" x 16.1", 3.7 sq ft of growing area) with the same AQUAvalve5 gravity-fed valve, just without the reservoir, seed trays, capillary spikes, and microgreen accessories that come with the Standard Kit. If you already own a reservoir or want to buy one separately, the Slim gives you the core system for under $100. Place fabric pots, perforated pots, or seed trays on the capillary mat and let it bottom-feed each container exactly what it needs. No pumps, no timers, no electricity. Free shipping on orders over $49 30-day returns on all orders Serving growers since 2006 See it in action How the Tray2Grow system works Side by side Hand watering pots vs. the Tray2Grow Slim Hand watering Water every pot individually, once or twice per day Uneven moisture between pots, some dry while others overwater Leave for a weekend and risk wilted or stressed plants Runoff collects in saucers, creating salt buildup and root rot risk Top watering compacts soil over time, reducing oxygen at the root zone Requires timers, pumps, or drip lines to automate Tray2Grow Slim AQUAvalve5 fills the tray automatically when it dries, feeds all pots at once Capillary mat delivers even moisture to every container on the tray Fill your reservoir and leave for days or weeks at a time Bottom-fed irrigation pulls water up through the root zone, no standing runoff Soil structure stays intact, roots get consistent oxygen exchange Zero electricity, zero pumps. Gravity and capillary action do everything What makes it different The essentials, nothing extra AQUAvalve5: plant-driven irrigation 0 watts The valve opens when the tray dries out and closes when it refills. Your plants control the cycle, not a timer. No electricity, no pump, no programming. Capillary mat + root control sheet The mat wicks water up from the tray into each pot evenly. The root control sheet sits on top to prevent roots from growing down into the mat and clogging it. Works with fabric pots, plastic pots, seed trays, and microgreen trays Any container with drainage holes or permeable walls works on this tray. Fabric pots, air pots, standard nursery pots, 1020 seed trays, and AutoPot microgreen trays all fit. 3.7 sq ft of growing area, fits a 4x2 tent or a wide windowsill Tray dimensions are 43.9" long x 16.1" wide x 3.8" deep. Three guide holes per side accept garden canes for trellising. Three embedded spirit levels for fast, accurate setup The AQUAvalve5 needs a level surface to function correctly. Three built-in bubble levels let you verify alignment without a separate tool. Slim Kit = tray only, no reservoir included Under $100 Already own a FlexiTank, hard-sided tank, or other reservoir? The Slim Kit gives you the tray and valve without paying for a tank you don't need. Specs Technical details Tray Dimensions 43.9" L x 16.1" W x 3.8" D Growing Area 532 sq in (3.7 sq ft) Valve AQUAvalve5 (gravity-fed) Power Required None (0 watts) Pipe Size 3/8" OD (3.3 ft included) Spirit Levels 3 (embedded in tray) Materials BPA-free, food-safe plastic Trellis Holes 3 per side (6 total) How the Tray2Grow Slim works 1 Level the tray and connect your reservoir Place the tray on a flat surface and use the three embedded spirit levels to verify it's even. Run the included 3/8" pipe from your reservoir (sold separately) to the tray's inlet grommet. 2 Lay the capillary mat and root control sheet Place the capillary sheet flat in the tray, then lay the root control sheet on top. The mat wicks water up, and the root sheet prevents roots from growing into it. 3 Set your pots on the tray Place any pots with drainage holes directly on the root control sheet. Fabric pots, air pots, nursery pots, and seed trays all work. The system handles up to the full 3.7 sq ft of tray space. 4 Fill the reservoir and walk away The AQUAvalve5 fills the tray when it dries and stops when water reaches the valve's shutoff point. Refill your reservoir as needed. That's the only maintenance.

If you're starting from scratch and want everything in one box, the Standard Kit with FlexiTank is the easier path. Call us: 716-217-0353 / help@happyhydro.com Questions Frequently asked questions What's the actual difference between the Slim Kit and the Standard Kit? Same tray, same AQUAvalve5, same capillary mat and root control sheet. The Standard Kit adds a FlexiTank reservoir with filter, capillary spikes for grow bags, seed trays, and copper slug tape. The Slim Kit is just the tray and the plumbing to connect it to a reservoir you already own. Can I use any reservoir, or does it have to be an AutoPot FlexiTank? Any gravity-fed reservoir works as long as it sits above the tray and connects via 3/8" tubing. The FlexiTank is purpose-built for AutoPot systems and includes the right filter, but a hard-sided tank or even a bucket with a bulkhead fitting and inline filter will work. The key requirement is that the reservoir must be higher than the tray so gravity can push water to the AQUAvalve. How level does the tray need to be? It needs to be level enough that all three spirit levels read centered. If the tray is uneven, the AQUAvalve5 won't shut off correctly and you'll get pooling on one side and dry spots on the other. Shims under the tray legs or a flat board underneath usually fix this in a few minutes. What size pots fit on the tray? The usable area is about 43.9" x 16.1", so you can fit several 1-gallon pots, a few 3-gallon pots, or two 5-gallon fabric pots side by side. For seedlings, four standard 1020 seed trays fit on the capillary mat. The only constraint is physical tray space and that all containers must have drainage holes or permeable walls so the capillary action works. Can I run nutrients through the system, or is it water only? You can run nutrients. Mix your nutrient solution in the reservoir and the AQUAvalve will deliver it the same as plain water. Keep your solution mild and stir the reservoir periodically to prevent settling. Growers run everything from mineral salts to organic teas through these systems successfully. Can I connect multiple Tray2Grow units to one reservoir? Yes. The system is modular. Use a tee connector (not included with the Slim, but available separately) to split the line from one reservoir to multiple trays. Each tray has its own AQUAvalve5, so they operate independently even on a shared reservoir. Just size your tank to match total demand. What if my Tray2Grow arrives damaged or defective?
